The wireless router can be regarded as a repeater, and forwards broadband network signals connected to the home wall to nearby notebook computers, mobile phones, flat boards supporting WLAN and all devices with WLAN functions through an antenna, so that the wireless router can generally support devices within 20 to be used online at the same time. It also has some other network management functions such as the functions of the dhcp service, firewall, mac address filtering, dynamic domain name, etc.
The wireless router SSID (Service Set Identifier) is a short for "service group identifier", which is an identifier of a wireless network, for identifying the identity of a wireless device found on a particular wireless network, also referred to as a WLAN name. All workstations and access points must use the same SSID to communicate with each other. The SSID value is case-specific and may be a favorite character such as a physical location identification of the wireless local area network, a name of a store, a company name, or a company name and division, a preferred tagline, etc.
In a well-established wireless lan system, encryption and authentication are security factors to be considered. The IEEE802.11 standard adopts WEP (Wired Equivalent Privacy: wired peer-to-peer encryption) protocol to set a special security mechanism for encryption of traffic and authentication of nodes. The method is mainly used for encrypting the link layer information data in the wireless local area network. WEP employs a symmetric encryption mechanism, and the encryption and decryption of data employ the same key and encryption algorithm. WEP encrypts the data portion of each data packet exchanged over the 802.11 network using a key. After encryption is enabled, two 802.11 devices must be enabled and have the same encryption key to communicate. The encryption key of the wireless network is also called WLAN password.

As shown in fig. 1 to 7, the router capable of automatically changing a wireless password according to the present invention is provided with a local area network communication program, an automatic key changing program, and an encryption key display program, and is externally provided with a display screen module.
Specifically, the local area network communication program: adopting an IEEE wireless local area network communication standard, encrypting/decrypting the service flow and authenticating the equipment node by using a WEP (web-defined protocol) wired equivalent encryption protocol; the WEP wired equivalent encryption protocol adopts a symmetric encryption key mechanism, and performs bidirectional encryption and decryption on interaction data through the same encryption key; wherein, both sides of the interactive data need to hold the same encryption key to start the WEP wired equivalent encryption protocol.
Specifically, the automatic key change program: the method comprises the steps of automatically changing an encryption key of a router according to a preset change configuration file, wherein the automatic key change comprises a random key generation program, a key change setting program and a key change configuration program; the random key generation program is used for generating a random key sequence, and the key change setting program is used for executing a key change step related to key change; the key change configuration program is used for setting a change configuration file related to key change.
Specifically, the encryption key display program: the method comprises the steps that an encryption key of a router is displayed through a display screen module according to a preset display configuration file; the key display device comprises a key reading program, a display data setting program and a key display configuration program; the key reading program is used for circularly reading the encryption key currently used and caching for standby; the display data setting program is used for executing a key display step; the key display configuration program is used for setting a key display related display configuration file.
It should be noted that: the existing wireless router wireless name (SSID) and wireless password (encryption key) are generally configured in a system (such as an embedded Linux system) file of a router CPU chip, and a Web server program is run in the system, so that a user configures the wireless name (SSID) and the wireless password through a Web page of a client. When the router is configured, a computer is required to be connected with a LAN port of the router through a network cable, then a webpage of the router is accessed, and settings such as wireless passwords of the router are changed in a webpage interface; after the setting is completed, the user needs to memorize the set wireless password, and other devices need to input the password when accessing the wireless network. However, this password setting flow also brings about the following problems:
1. existing wireless router users need to record the password themselves and enter the password when other devices connect to the network. For the case of not connecting to the network for a long time or frequently changing the password, the user's account may forget the password and need to reset, which is very inconvenient.
2. The wireless password of the existing router is not automatically changed after being set. When the password is required to be changed, other equipment (such as a computer) is connected with the router, and the router is manually set by a user, which is troublesome.
3. For the situation that a guest needs to access a wireless network (such as a wireless network in a restaurant) often, the host needs to change the wireless password frequently and print the wireless name and the wireless password on paper and paste the wireless name and the wireless password on a wall, but the host needs to reprint or change after changing the wireless password, which is very inconvenient and intuitive.
Based on the above-mentioned drawbacks, as shown in fig. 2 (WLAN name and wireless name SSID are equivalent, WLAN password and wireless password encryption key are equivalent), the body of the wireless router device provided in this embodiment is provided with a display screen, and the display screen can display the wireless name and wireless password of the wireless router. When the router is used, the wireless password setting of the router can be intuitively seen, and the condition that the wireless password is forgotten is avoided. For the situation that the network is used by frequent visitors, the router is hung on a conspicuous place on the wall, so that the connection of the visitors to the wireless network can be facilitated.
The wireless router of this embodiment has an embedded system (generally a Linux system) running in a CPU chip, and automatically runs a control program when the embedded system is started. The control program can run continuously when the device is in a starting state. After the control program is started, the current time is firstly read from the system, and then whether the user starts the function of automatically changing the wireless password is judged. If the function of automatically changing the password is started, the control program reads the time of changing the password last time and determines whether to change the password; if the password needs to be changed, the control program randomly generates a new password, and then configures the new password and validates the new password. If the password is not required to be changed or the automatic password changing function is not started, the control program reads the current wireless name and wireless password information from the system, and then the display screen for transmitting the wireless signal information of the wireless router is displayed by the display screen according to the setting of the user.
The wireless password of the wireless router of the invention can be changed by the program timing in the router. The router changes the wireless cipher at regular intervals set by the user, and a new wireless cipher value is randomly generated by a program in the router. The new password generated by the wireless router can be displayed on a display screen of the router, so that a user can conveniently re-access the wireless network according to the new password. The function solves the problem that a user needs to manually change the wireless password and needs to record a new password by himself.
As a further solution, the router performs wireless network coverage on the peripheral area, if the device node in the coverage area needs to establish network connection with the router, the device node needs to adopt the same IEEE wireless local area network communication standard as the router, and starts the WEP wired equivalent encryption protocol to encrypt the interactive data.
As a further solution, when the wireless local area network is established, the local area network communication program sets the SSID corresponding to the current line local area network, and reads the encryption key set by the current automatic change key program; the equipment nodes in the coverage area can scan to obtain the SSID corresponding to the local area network, and input the encryption key matched with the SSID, so that the current wireless local area network is accessed.
Specifically, after the current encryption key is read by the encryption key display program, the current encryption key is displayed in real time through the display screen module; the installer places the display screen module in the appointed area, so that the user can check the SSID and the encryption key of the current local area network through the display screen module in the appointed area, and after the user inputs the SSID and the encryption key through the equipment node, the user establishes network connection with the corresponding wireless local area network.
