Exemplary methods and systems for acquiring network credentials for network access are described. The exemplary method comprises receiving network configuration information from a network device on a communication network, generating a credential request, transmitting the credential request to a credential server over a standard protocol of the network device, receiving the credential request response, and providing a network credential from the credential request response to the network device to access the communication network.

Description

  The present invention relates generally to accessing a communication network. More specifically, the present invention relates to automatic access to wireless communication networks.

  With the increasing access to information using the network, the reliance on network communications has become even greater for various activities. With such dependencies, the expectation that network access will be everywhere increases. Network access for mobile users has been especially enhanced by improvements in wireless technology. Various cellular (eg, GSM, CDMA, etc.), Wi-Fi (ie, IEEE 802.11), WiMAX (ie, IEEE 802.16), and other technologies enable potential networking A wide range of access options has become possible for users. Many wireless access points or “hot spots” are accessible only to the local geographic area (sometimes as fine as a specific work address or other address). In addition, effectively located hotspots can provide public or private network access to various groups of people.

  The hotspot owner or administrator requires a password or the like in order to be able to access the user. As a result, users at multiple hotspots must manage a large number of passwords by storing or remembering. Many users can store their passwords on the laptop computer used to access the hotspot. However, not all devices that can access the hotspot are laptop computers. That is, mobile phones, personal digital assistants (PDAs), and many other devices now support wireless access. Unfortunately, users often cannot easily enter a password into the device or store a password in the device. For example, some devices that support wireless access may not have a keyboard. Even when the device includes a keyboard, the keyboard is often small, and keyboard functionality may be limited, especially for users with poor fingertip dexterity.

  When a user stores his password on the laptop computer, the user must first access the laptop computer and store the correct password in the laptop computer. When the password changes, the user must update the password stored on the laptop computer. In addition, storing a username and password on a device can pose a security problem if the device is lost or stolen.

  In addition, the user generally has to enter a password, a username, and walk through the web site to gain network access. Such a process is time consuming and the user may be forced to enter incorrect information and re-enter the data.

  When users enter passwords manually, they do not try to remember difficult passwords. As a result, access with simple passwords is subject to hacking and may therefore compromise the user's network access, hotspots, and / or the user's personal information. Furthermore, if a user's simple password is hacked or easily guessed, the user's network access may be stolen.

  Exemplary methods and systems for providing network credentials for network access are described. The exemplary method receives a credential request from a digital device via a network device and identifies a network record based on at least some information in the credential request. Obtaining a network credential from a plurality of network credentials based on the network record, and receiving a credential request response including the network credentials obtained from the plurality of network credentials. Sending to the digital device.

  The method may further include decrypting the credential request (plain culture), authenticating the credential request, and encrypting the credential request response. The method may further include obtaining an encryption key based on the digital device. The credential request is received with the network device standard protocol. This standard protocol is DNS.

  The credential request may include a location identifier. The method may further include receiving a confirmation access response from the digital device.

  An exemplary system for providing network credentials may include a credential request module and a credential request response module. The credential request module is configured to receive a credential request from a digital device via a network device. The credential request response module identifies a network record based on at least some information in the credential request and, based on the network record, from one network credential to one network credential. It is configured to obtain a certificate and send a credential request response including the network credential to the digital device.

  A program may be stored in a computer-readable medium. The program can execute on the processor a method of providing network credentials. The method includes receiving a credential request from a digital device via a network device, identifying a network record based on at least some information in the credential request, the network Obtaining one network credential from a plurality of network credentials based on the record, and a credential request response including the network credential obtained from the plurality of network credentials, Sending to the digital device.

FIG. 3 is a block diagram of an exemplary credential server.

  Embodiments of the present invention provide systems and methods for providing network credentials. In the exemplary embodiment, the credential server receives a request for network credentials from a digital device at the hotspot. This request can be formatted as a standard protocol relayed from the hotspot to the credential server. The credential server identifies a network record based on at least some information contained in the request and sends a network credential associated with the network record to the digital device. The digital device receives the network credentials and provides those network credentials to the network device to gain network access.

  FIG. 1 shows a schematic diagram of an environment 100 in which embodiments of the present invention may be implemented. In the exemplary embodiment, the user enters a hotspot using digital device 102. The digital device 102 automatically sends the credential request as a standard protocol via the network device 104. This credential request is forwarded to the credential server 116. The credential server 116 sends a credential request response back to the digital device 102 based on the information in the credential request. The credential request response includes a network credential, which is used by the digital device 102 to gain access to the communication network 114, the network device 104, the authentication server 108, or the access It can be provided to the controller 112.

  In various embodiments, the hotspot includes a network device 104, an authentication server 108, a DNS server 110, and an access controller 112, which are coupled to a local area network 106 (eg, “Walled Garden”). The Network device 104 can include an access point that enables digital device 102 to communicate with authentication server 108, DNS server 110, and access controller 112 via local area network 106. Digital device 102 may include a laptop, mobile phone, camera, personal digital assistant (PDA), or any other computing device. The authentication server 108 is a server that requests network credentials from the digital device 102 before the digital device 102 accesses the communication network 114. The DNS server 110 provides a DNS service via the local area network 106. DNS server 110 can relay requests across communication network 114 to other DNS servers (not shown). Access controller 112 is an access device such as a router or bridge that allows a device operably coupled to network device 104 to communicate with a device coupled to communication network 114.

  Although the hotspots in FIG. 1 illustrate separate servers coupled to the local area network 106, those skilled in the art will recognize devices coupled to the local area network 106 (eg, servers, digital It will be appreciated that there can be any number of devices, access controllers, network devices). In some implementations, the local area network 106 is optional. In one example, authentication server 108, DNS server 110, and access controller 112 are coupled directly to network device 104. In various embodiments, the authentication server 108, DNS server 110, and access controller 112 are combined in one or more servers or in one or more digital devices. In addition, although FIG. 1 shows wireless access, the digital device 102 may be coupled to the network device 104 via wireless or wired (such as ten base tee (10baseT)).

  To access the communications network 114, the authentication server 108 may ask the digital device 102 to provide one or more network credentials for accessing the hotspot. This network credential includes, for example, a username and password for an account associated with this hotspot. In alternative embodiments, network credentials other than username and password may be utilized.

  In accordance with an exemplary implementation, digital device 102 can dynamically obtain network credentials from credential server 116. The digital device 102 identifies the identity of the digital device 102 (or the user of the digital device 102) and details about the network device 104 (eg, the name of the network device 104 or the Wi-Fi service provider). A credential request including the above is sent to the credential server 116.

  In one example, when the digital device 102 enters a hotspot, the network device 104 may provide an IP address to which a DNS query is submitted, for example, via DHCP (Dynamic Host Configuration Protocol). This credential request is formatted as a standard protocol. In one example, the credential request can be formatted as a DNS request. This credential request is a text record request (eg, TXT) that includes a standard record type so that it is not blocked (blocked) by the network infrastructure (eg, access controller 112). A more detailed description of the process for obtaining network credentials is now in co-pending termed “System and Method for Acquiring Network Credentials” filed September 6, 2007. U.S. Patent Application No. ____, which is incorporated herein by reference.

  In some implementations, a credential request is received at the DNS server 110. DNS server 110 may forward this credential request to credential server 116 to obtain network credentials. In the exemplary embodiment, credential server 116 performs a lookup to determine the proper network credential (s) and passes the network credential to DNS server 110. Can be sent back. The DNS server 110 forwards the network credentials back to the requesting digital device 102. In various embodiments, the proper network credential (s) is sent from the credential server 116 to the digital device 102 via the same path as the transmission of the credential request.

  Although only one DNS server 110 is shown in FIG. 1, the credential request includes a DNS server before it is received at the credential server 116 (but is not limited to a DNS server). It can be transferred through any number of servers. In other embodiments, the credential request is forwarded directly from the network device 104 to the credential server 116.

  In some implementations, the credential request response from the credential server 116 includes a username, password, and / or login procedure information. This login procedure information includes, for example, an HTML form element name, a submission URL, or a submission protocol. In some implementations, the network credential response is encrypted by the credential server 116 using an encryption key associated with the digital device 102 before being sent back to the digital device 102.

  When the digital device 102 receives the network credential response, the digital device 102 submits (presents) the network credential (obtained from the network credential response) to the network device 104 in the authentication response. To do. In the exemplary implementation, the authentication response is forwarded to authentication server 108 and verified. In some implementations, the authentication server 108 includes an AAA server or a RADIUS server. A more detailed description of the process of gaining network access is a co-pending US patent entitled “System and Method for Obtaining Network Access” filed September 6, 2007. Application No. _____, which is incorporated herein by reference.

  It should be noted that FIG. 1 is exemplary. Alternative embodiments may include more, fewer, or functionally equivalent components, but still fall within the scope of this embodiment. For example, as previously described, the functions of various servers (eg, DNS server 110, credential server 116, authentication server 108) can be combined into one or two servers. That is, for example, the authentication server 108 and the DNS server 110 may include the same server, or the functions of the authentication server 108, the DNS server 110, and the access controller 112 may be combined into a single device.

  FIG. 2 is a block diagram of an exemplary credential server 116. The credential server 116 includes an authentication module 200, a network module 202, a credential request module 204, a credential request response module 206, an encryption / decryption module 208, a network record storage device 210, and an encryption key storage device. 212 is included. Modules include software, hardware, firmware, or circuitry, either individually or in combination.

  The authentication module 200 is configured to authenticate the credential request and provide security to the credential request response. In various implementations, the digital device 102 encrypts the credential request with an encryption key (eg, a shared encryption key, or an encryption key that is part of a key pair), or a credential. The request can be digitally signed. The authentication module 200 authenticates the credential request by encrypting the credential request using an appropriate encryption key acquired from the encryption key storage device 212. In one example, the digital device 102 generates a hash of the credential request and stores this hash in the encrypted portion of the credential request. The authentication module 200 decrypts the credential request (plain culture), generates a hash of the credential request response, and uses the generated hash as a hash contained in the credential request. Authentication is performed by comparison.

  In other implementations, the digital device 102 can generate a nonce (ie, a random value) and store the nonce in a portion of the digitally signed credential request. The authentication module 200 decrypts the digital signature to authenticate the credential request and obtain a nonce. In various implementations, the authentication module 200 incorporates a nonce into the credential request response when the credential request response module 206 generates a credential request response (described below). Next, the authentication module 200 or the encryption / decryption module 208 encrypts the credential request response. When the digital device 102 decrypts the credential request response, the digital device 102 obtains a nonce from the credential request response and sends the nonce into the credential request. Further authentication is performed by comparing with the given nonce.

  The network module 202 is configured to receive a credential request and send a credential request response over the communication network 114.

  The credential request module 204 receives a credential request from the network module 202. This credential request is a standard protocol. In one example, the credential request is a UDP protocol (eg, DNS).

  In the exemplary implementation, credential request module 204 obtains the DDID and SSID from the credential request. The DDID identifies (identifies) the digital device 102, the user of the digital device 102, and / or the user associated with the network record. The SSID identifies a hotspot or hotspot service provider (ie, operator).

  The credential request module 204 or the credential request response module 206 identifies a network record based on the DDID and SSID. A network record is a record (directly or indirectly (eg, a relational database)) associated with a DDID and SSID. In one example, the network record includes the network credentials necessary to provide network access to the digital device 102 associated with the DDID at a hotspot associated with the SSID. The network record is stored in the network record storage device 210.

  The credential request response module 206 can generate a credential request response. In various implementations, the credential request response module 206 receives network credentials associated with the DDID and SSID from the network record. In some implementations, this network credential includes a credit card number. In one example, the digital device 102 receives network credentials, obtains a credit card number, and provides this credit card number to the authentication server 108. Next, in some examples, the authentication server 108 charges the credit card associated with this credit card number or uses this information to verify the user's identifier before allowing network access. To do.

  Further, in various embodiments, the network credentials include login procedure information. In one example, these network credentials include a username and password that are to be provided in a form (eg, an authentication form) obtained by the digital device 102 from the authentication server 108. In some implementations, the login procedure information instructs the digital device 102 to place the network credentials in the identification field in the form before submitting the completed form to the authentication server 108. One skilled in the art will appreciate that there are many ways to provide credentials to the authentication server 108. The process of providing credentials to an authentication server is further described in a co-pending United States application entitled “System and Method for Observing Network Credentials” filed September 6, 2007. It is described in patent application ____.

  The credential request response module 206 or the encryption / decryption module 208 encrypts the credential request response using the encryption key associated with the DDID or credential request. In one example, the credential server 116 stores one or more shared encryption keys. Each shared encryption key is shared by at least one digital device 102. The credential request response module 206 encrypts the credential request response using the shared encryption key associated with the digital device 102 (eg, this shared encryption key is associated with the DDID). The credential request response module 206 or encryption / decryption module 208 may also encrypt the credential request with an encryption key that is part of the key pair. There are many ways for the encryption / decryption module 208 to encrypt the credential request.

  The encryption / decryption module 208 decrypts the credential request and encrypts the credential request response. As previously described, the encryption / decryption module 208 decrypts the digital signature on the credential request. In one example, the encryption / decryption module 208 decrypts the digital signature based on the encryption key associated with the DDID contained in the credential request. The encryption / decryption module 208 may also encrypt the credential request response. In one example, the encryption / decryption module 208 encrypts the credential request response based on an encryption key associated with the DDID (eg, a shared encryption key or an encryption key that is part of a key pair).

  In various implementations, the encryption / decryption module 208 can encrypt the network record contained in the network record storage device 210 and manage the encryption key storage device 212. The encryption / decryption module 208 may also establish secure communication (eg, via SSL or HTTPS) with the digital device while storing network credentials. Such a process is further described in FIG. According to some implementations, the encryption / decryption module 208 may be omitted.

  The network record storage device 210 and the encryption key storage device 212 store the network record and the encryption key, respectively. The network record storage device 210 and the encryption key storage device 212 include one or more databases. In one example, the network record store 210 stores network records. The network record includes DDID, SSID, and network credentials. The network record also provides a username and password for the user to access the network record, modify or update the network record, or store the network record in the credential server 116. Including.

  In various implementations, the network record may allow multiple digital devices 102 to use the same network credentials. In one example, a user owns multiple digital devices 102. Multiple DDIDs, each associated with a different digital device 102, are included in the same network record. In some implementations, multiple devices may be associated with one or more network records, and such one or more network records are associated with a single user. As a result, this user uses any number of digital devices 102 to obtain network credentials for the hotspot. Those skilled in the art store and organize network records and / or information contained in network records (eg, in different data structures, databases, records, organization schemes, and / or techniques). It will be appreciated that there are many ways that can be done.

  FIG. 3 is a flowchart of an exemplary process for providing network access to digital device 102. In step 300, when the digital device 102 first enters the hot spot, the digital device 102 scans the local area network 106 for examination. In step 302, as a result of the scan, the network device 104 provides network configuration information. This network configuration information includes one or more IP addresses for accessing the DNS server 110.

  In step 304, a credential request is generated by the digital device. Next, in step 306, the credential request is sent to the DNS server 110 using one of the IP addresses previously received from the network device 104.

  In step 308, the credential server 116 is identified by the DNS server 110 based on the credential request. In other embodiments, the DNS server 110 forwards the credential request to the credential server 116. When the DNS server 110 cannot resolve the DNS request locally, the credential request is forwarded to another DNS server on the communication network 114 (eg, via port 53). The other DNS server then forwards the credential request to the credential server 116. In step 310, the credential request is forwarded directly or indirectly to the credential server 116 through one or more other DNS servers on the communication network 114.

  In step 312, the credential server 116 identifies the required network credentials based on the credential request. For example, this credential request includes not only an identifier for a hotspot SSID (eg, a service provider such as an operator) but also an identifier for the digital device 102 (ie, DDID). These identifiers are compared with a table of such identifiers (eg, network records) by the credential request module 204 or the credential request response module 206 to determine the proper network credentials. Next, in step 314, a credential request response is generated by the credential request response module 206, and in step 316, the credential request response is relayed back to the DNS server 110. In step 318, DNS server 110 forwards the credential request response back to the digital device.

  Next, in step 320, the digital device 102 obtains network credentials from the credential request response. Next, in step 322, the network device 104 is provided with network credentials. In step 324, after verifying the network credentials, the network device 104 provides network access to the digital device 102.

  Turning now to FIG. 4, an exemplary credential request 400 is shown in further detail. According to an exemplary implementation, credential request module 204 generates credential request 400. In one embodiment, the credential request 400 may be a DNS string having a structure including a location identifier 402, a sequence identifier 404, a signature 406, a DDID 408, a SSID (service set identifier) 410, and a version identifier 412. is there.

  Optional location identifier 402 indicates the physical or geographical location of digital device 102, network device 104, authentication server 108, or access controller 112. In various implementations, the location identifier 402 may be used at the credential server 116 to track hot spot usage, not only the digital device 102 but also the user of the digital device 102.

  The sequence identifier 404 includes any number or any set of numbers used to respond to the next request to the credential server 116 to determine if the login was successful. That is, the sequence identifier 404 provides a correlation mechanism that causes the credential server 116 to verify the login process.

  In the exemplary embodiment, signature 406 includes a cryptographic signature (ie, a digital signature) that is used to prevent spoofing. The signature 406 to the request from the digital device 102 is verified by the credential server 116. If the signature 406 is not valid, the request is rejected by the credential server 116.

  DDID 408 includes an identifier of digital device 102. For example, DDID 408 includes a MAC address or any other identifier of digital device 102.

  The SSID 410 includes an identifier of a network access point or Wi-Fi service provider. For example, the SSID 410 may include the name of a Wi-Fi service provider or the name of the venue that operates the network device 104.

  The version identifier 412 can identify the protocol or format of the credential request 400. For example, the digital device 102 generates a credential request 400 and organizes the data in a number of different formats. Each different format is associated with a different version identifier. In some implementations, the components of the credential request response module 206 may be updated, reconfigured, or gradually changed, which may indicate that the credential request 400 Affects the structure of As a result, the credential server 116 receives a plurality of credential requests 400 that are variously formatted. The credential server 116 accesses the required information from each credential request based on the respective version identifier.

  FIG. 5 is a block diagram of an exemplary credential request response. According to an exemplary implementation, credential request response module 206 can generate credential request response 500. In one implementation, the credential request response 500 includes ciphertext 502. The ciphertext 502 includes an optional nonce 504 and credential information 506. The credential information 506 includes key / value pairs (508-510).

  As previously described, the credential request response may be formatted as a DNS response that includes ciphertext 502. The ciphertext 502 includes network credentials (eg, username, password, login procedure information). Although the credential request response 500 is shown as including encrypted text 502, the text in the credential request response 500 need not be encrypted.

  The ciphertext 502 may include a nonce. The nonce is obtained from the credential request as previously described. When the credential request response 500 is received at the digital device 102, the digital device 102 compares the nonce in the credential request response 500 with the nonce sent in the credential request. Authenticate. In FIG. 5, the nonce is shown as being in the credential request response 500, but the nonce is arbitrary.

  The credential information 506 includes a user name, password, login procedure information, or a combination thereof. The credential information 506 includes key / value pairs (508-510). There may be any number of key / value pairs in the credential information 506. The key / value pair represents the credential information that is received and converted at the digital device 102. The credential information 506 is shown as a key / value pair for exemplary purposes only. The credential information 506 may be in an arbitrary format that is not necessarily limited to key / value pairs.

  FIG. 6 is a flowchart of an exemplary method for providing network credentials. In step 602, the credential server 116 receives a credential request from the digital device 102.

  In various embodiments, the credential server 116 encrypts and authenticates the digital signature using an encryption key. Next, in step 604, the credential server 116 identifies this network record based on the DDID and SSID contained in the network record. In one example, the credential request response module 206 obtains one or more network records associated with the DDID in the credential request. Next, the credential request response module 206 identifies at least one network credential associated with the SSID in the acquired network record (s).

  In step 606, the credential request response module 206 obtains the identified network credential (s) from the selected network record. In one example, the credential request response module 206 identifies a username and password that a user of the digital device 102 must provide to the authentication server 108 to gain network access. In step 608, the credential request response module 206 generates a credential request response including network credentials (eg, username, password) for the digital device 102.

  In some implementations, the credential request response module 206 identifies login procedure information as part of the network credential. The credential request response module 206 obtains the login procedure information from a network record (eg, the same network record that includes a password associated with the SSID). This login procedure information includes a form identifier and instructions (eg, parameters) that the digital device 102 follows to gain network access. In one example, the digital device 102 obtains the form identifier and instructions from the network credentials that are in the credential request response. The digital device 102 identifies the form received from the authentication server 108 and the input data based on these form identifiers and instructions. In another example, the digital device 102 provides information to the authentication server 108 to gain network access based on login procedure information included in the credential request response. The process of providing information to the authentication server 108 is further described in U.S. Patent Application No. ______________________________________________________________________________________, filed Sep. 6, 2007, which is filed on September 6, 2007. Have been described.

  FIG. 7 is another flowchart of an exemplary method for providing network credentials. The digital device 102 searches for and finds available wireless networks via the network device 104. In step 702, the digital device 102 receives network configuration information while connected to the hotspot. The network configuration information includes an identifier for the network device 104 or DNS server 110. In one example, the digital device 102 receives a DNS server IP address (eg, for the DNS server 110) during the connection process.

  In step 704, the digital device 102 generates a credential request. This credential request includes a sequence identifier, DDID, and SSID. In step 706, the digital device 102 optionally generates a nonce and digitally signs the credential request with the encryption key. In step 708, the digital device 102 sends a credential request as a standard protocol. The network device 104 receives the credential request and forwards the credential request to the communication network 114. In various implementations, the network device 104 may provide a credential request to the DNS server 110, and the DNS server 110 forwards the credential request to the credential server 116.

  In the exemplary embodiment, the credential request module 204 of the credential server 116 receives the credential request. The credential request module 204 obtains an encryption key associated with the DDID in the credential server 116 from the encryption key storage device 212. Next, the credential request module 204 performs authentication by decrypting the digital signature to the credential request. Further, the credential request module 204 obtains a nonce and a sequence identifier from the credential request.

  Next, the credential request response module 206 of the credential server 116 can obtain the network record associated with the DDID and SSID from the network record storage device 210. The credential request response module 206 obtains a network credential from this network record and generates a credential request response. This credential request response includes a network credential and a nonce. The encryption / decryption module 208 uses the encryption key associated with the DDID acquired from the encryption key storage device 212 to encrypt the credential request response. In some implementations, this credential request response is formatted as a standard protocol (eg, DNS).

  In step 710, the digital device 102 receives a credential request response. Next, in step 712, the digital device 102 authenticates this credential request response. In one example, the digital device 102 decrypts the credential request response using the same key that is used to digitally sign the credential request. The digital device 102 further obtains the nonce in the credential request response and compares the nonce with the nonce sent in the credential request for further authentication. In step 714, if the credential request response is found to be authentic, the digital device 102 obtains a network credential from the credential request response.

  In step 716, the digital device 102 identifies authentication requirements associated with network access. In various implementations, the digital device 102 determines the proper information and network credentials to provide to the authentication server 108. In one example, the digital device 102 obtains one or more network access pages from the authentication server 108. The digital device 102 accesses the appropriate network access page from the authentication server 108 and makes a selection automatically. In one example, the digital device 102 can automatically make its “selection” (eg, activation of a button in a network access page, check of a select box, selection of a radio button).

  For example, the credential request response module 206 provides instructions to the digital device 102 for automatic selection within the network access page. As described herein, the network access page includes one or more web pages obtained from the authentication server 108, one or more tags, or a combination of both. In one example, the software contained in the digital device 102 automatically checks all select boxes in the network access page. Next, the digital device 102 unchecks the select box based on the login procedure information. One skilled in the art will recognize that there may be many ways to make a selection automatically. In other implementations, the digital device 102 receives an XML tag from the authentication server 108. The digital device 102 provides information based on the XML tag and instructions in the login procedure information to the authentication server 108 to gain network access.

  In step 718, digital device 102 provides network credentials to network device 104 to gain network access to communication network 114. In one example, the credential request response module 206 obtains one or more forms from the authentication server 108, puts one or more network credentials in such a form, and enters these completed forms. This is provided to the authentication server 108. In another example, the credential request response module 206 provides network credentials to the authentication server 108 as needed. Once the network credentials are received at the authentication server 108, the authentication server 108 can enable communication between the digital device 102 and the communication network 114. In one example, the authentication server 108 commands the access controller 112 so that the digital device 102 can access the communication network 114.

  The digital device 102 can then test network connectivity to verify network access. In one example, the digital device 102 sends a request to the credential server 116 to determine if the communication network 114 is available. In some implementations, the query or command includes a sequence identifier that was previously submitted in the credential request. If network access is successful, the credential server 116 may receive the request and obtain a sequence identifier. The credential server 116 then verifies that the network access was successful.

  FIG. 8 is a flowchart of an exemplary method for receiving and storing network credentials. In various implementations, a user can generate a network record and store the network record in the credential server 116. For example, the credential server 116 may provide a credential storage module (illustrated) that provides a graphical user interface (GUI) that allows a user to create, store, update, remove, and modify network records. Not included).

  In step 802, the credential server 116 provides the user with a network credential request form. In one example, the credential server 116 provides the network credential request form to the user as one or more web pages over the Internet. The network credential request form is configured to receive a service provider name (eg, operator name) and / or SSID and network credentials.

  The name of the service provider is the name of the hotspot, one or more components related to the hotspot (eg, network device 104), or the entity that operates the local area network 106 infrastructure. including. In some implementations, the name of the service provider includes the name of an organization that manages one or more hotspots for another service provider. In one example, even if the hotspots have different service providers, both the coffee shop and the bookstore can manage these hotspots using a third-party manager. In some implementations, the network credential request form is configured to receive the name of this third party administrator. In some implementations, the name of the service provider includes the name of the organization (eg, aggregator) that resells access to the hotspot network.

  The network credential request form may also receive an SSID as a network service selection. In one example, the network credential request form includes pull-down menus of different service providers and / or hot spots that the user can select. For example, the user can select “Starbucks” or “San Francisco International Airport” as a hot spot. The user is given further options such as the geographical location of this hot spot. The user also selects a service provider. For example, the user selects “T-Mobile” as the service provider. The network credential request form then allows the user to select from one or more various hotspots associated with the T-Mobile. Such “selection” (s) is then stored as a network record. Alternatively, the network service identifier associated with such “selection” (s) is generated as an SSID.

  Further, the network credential request form receives network credentials from the user. For example, the user inputs a user name, a password, and a passcode as a network credential in the network credential request form. In some implementations, after the network credential request form receives the SSID, the network credential request form determines the type of network credential sought. For example, the network credential request form identifies the information necessary to access the network at the “San Francisco International Airport” hotspot previously selected by the user. The network credential request form then selects fields or selections to allow the user to enter only the information (eg, username, password) necessary to gain network access at this hotspot. Generate.

  The credential server 116 may also ask the user to register before receiving the network credential request form. During registration, the user must agree to the terms of service and enter customer information. The customer information includes a username and password to access the credential server 116 and store the network credentials. Optionally, the customer information includes the user's address, contact information, and payment options for the user to use the services provided by the credential server 116.

  In step 804, the credential server 116 receives the customer information and network service selection via the network credential request form. In step 806, the credential server 116 obtains network credentials. In step 808, the credential server 116 receives customer information. In step 810, the credential server 116 associates the network credential with customer information, network service selection, network credential (s) and generates a network record. Next, in step 812, the network record is stored.

  In some implementations, the user manually accesses the credential server 116 via the Internet. In other embodiments, the user downloads the network credential software and installs the software on the digital device 102. The network credential software identifies the DDID of the digital device 102 and sends the DDID to the credential server 116. In other embodiments, the network credential software is preinstalled on the digital device 102. When the digital device 102 first launches the network credential software, the network credential software identifies the DDID of the digital device 102 and sends the DDID to the credential server 116.

  The user can enter the SSID into the network credential software (eg, identify a service provider or hotspot). The user can also enter network credentials into the network credentials software. After the network credential software obtains the DDID, SSID, and network credential, the network credential software uploads the information to the credential server 116, and the credential server 116 Is stored in the network record. In various implementations, the network credential software may be downloaded from the credential server 116.

  The storage system 904 is an arbitrary storage (storage device) configured to acquire and store data. Some examples of the storage system 904 include flash drives, hard drives, optical drives, and / or magnetic tape. In some implementations, the credential server 116 includes a memory system 902 that takes the form of RAM and a storage system 904 that takes the form of flash data. Both the memory system 902 and the storage system 904 include computer readable media that can store instructions or programs that can be executed by a computer processor including the processor 900.

  An optional input / output (I / O) interface 906 is any device that receives input from a user and outputs data. Optional display interface 910 is any device configured to output graphics and data to a display. In one example, display interface 910 is a graphics adapter. It will be appreciated that not all digital devices 102 include either an I / O interface 906 or a display interface 910.

  A communications network interface (com.network interface) 908 may be coupled to a network (eg, local area network 106 or communications network 114) via a link 912. The communication network interface 908 supports communication via, for example, an Ethernet connection, a serial connection, a parallel connection, or an ATA connection.
