Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a method for verifying a digital certificate according to an embodiment of the present invention. The present embodiment is applicable to a case where authenticity and timeliness of a digital certificate of a party to be authenticated for transmitting information are authenticated at the time of information transmission. The method for verifying the digital certificate provided by the embodiment of the invention can be implemented by a device for verifying the digital certificate provided by the embodiment of the invention, and the device can be implemented in a software and/or hardware mode and is integrated in an electronic device for implementing the method, wherein the electronic device is provided with a pre-developed mutually trusted platform, and at least two certificate centers (namely CA institutions) are registered in the home type platform.
Specifically, referring to fig. 1, the method specifically includes the following steps:
s110, determining a certificate center to be mutually trusted in response to a verification request of a digital certificate of a party to be verified by a requester.
Specifically, in order to realize mutual trust between different certificate centers, so as to support that a certain certificate center can accurately verify authenticity and timeliness of a digital certificate issued by a sender when another certificate center is used for information transmission, the embodiment can develop a mutual trust platform in advance, a large number of certificate centers are registered in the mutual trust platform, and meanwhile mutual trust between different certificate centers is realized by adopting a cross-certification mode.
In this embodiment, when transmitting information to another terminal or a server during information transmission, in order to avoid that the transmitted information is tampered in the middle, the sender may be used as the party to be verified in this embodiment, and then a digital certificate of the party to be verified is used to sign the transmitted information, so as to ensure the confidentiality and integrity of data in the transmission process of the wireless device. Specifically, when the other terminal or the server receives the information transmitted by the party to be verified, the digital certificate of the party to be verified can be analyzed, and whether the received information is tampered or not is judged by verifying whether the digital certificate of the party to be verified is true or not. Therefore, the embodiment can take the other party of information transmission (such as another terminal or a server end for receiving the information transmitted by the party to be verified) as a request party, initiate a verification request of the digital certificate of the party to be verified to a pre-opened mutually trusted platform, and verify the authenticity and validity of the digital certificate of the party to be verified by the mutually trusted platform so as to judge whether the digital certificate of the party to be verified is trusted or not.
Because the mutually trusted platform registers a plurality of certificate centers, the certificate center for issuing the digital certificate for the party to be authenticated and the certificate center responsible for the party to be authenticated may not be the same certificate center, so that the certificate center corresponding to the party to be authenticated cannot directly verify whether the digital certificate of the party to be authenticated is trusted, in this embodiment, after receiving the verification request of the digital certificate of the party to be authenticated sent by the party to be authenticated, the mutually trusted platform firstly analyzes the verification request to obtain the digital certificate carried by the party to be authenticated when transmitting information, and the information of the certificate center responsible for the party to be authenticated to verify the certificate, and then analyzes the digital certificate of the party to be authenticated to obtain the certificate center for issuing the digital certificate for the party to be authenticated, thereby determining the certificate center to be mutually trusted. For example, if the mutually trusted platform receives a request of a requesting party for verifying a digital certificate of a party to be verified, the mutually trusted platform directly determines a first certificate center for issuing the digital certificate of the party to be verified and a second certificate center pointed by the requesting party, and then takes the first certificate center and the second certificate center as the certificate centers to be mutually trusted.
It should be noted that, the digital certificate of the party to be verified is issued by the registered certificate center in the mutually trusted platform, and in order to realize the accurate verification of the digital certificate of the party to be verified, the certificate center responsible for the verification of the certificate of the requesting party is also registered in the mutually trusted platform, so in this embodiment, the certificate centers to be mutually trusted are all registered certificate centers in the mutually trusted platform, and the corresponding mutually trusted is realized in a cross authentication manner between different registered certificate centers in the mutually trusted platform, so as to judge whether the digital certificate of the party to be verified is trusted or not by adopting a trust transfer manner.
It should be noted that, in this embodiment, the verification of the digital certificate of the party to be verified by the requester may refer to that the party to be verified actively sends a request to the requester to verify whether the digital certificate of the party to be verified is trusted, or may refer to that the requester logs in the mutually trusted platform in this embodiment on a local device (such as a mobile terminal or a computer terminal), and then actively verifies whether the digital certificate of the party to be verified is trusted. The specific verification scenario of the digital certificate of the party to be verified is not limited in this embodiment.
S120, constructing a corresponding mutual trust logic tree according to trust chain data formed by a certificate center to be mutually trusted after the mutual trust platform is registered.
Optionally, when each certificate center is registered in the mutual trust platform, corresponding cross authentication is established between each registered certificate center and the registered certificate center so as to realize trust transfer between different certificate centers, that is, a certain or a plurality of specific certificate centers are screened out from all registered certificate centers, then a private key of the specific certificate center is utilized to issue a corresponding digital certificate for the registered certificate center, so that equipment trusting the specific certificate center can trust the registered certificate center, at this time, through analyzing a trust transfer process of a certificate when each registered certificate center is registered, corresponding trust chain data is recorded, the trust chain data is used for indicating that after any certificate center is registered in the mutual trust platform, the trust transfer process of the certificate center is performed between different centers in a cross authentication mode, for example, certificate centers A, B, C and D are registered on the mutual trust platform, A is used as a certificate center which is registered first to the mutual trust platform, corresponding digital certificates are issued for B and C, and C is signed for D, at this time, and D is a trust chain is indicated as long as D is analyzed, and trust data can be obtained by D, namely, as long as D is a trust chain is B, C.
Taking a new certificate center registration by the mutual trust platform as an example, the mutual trust platform firstly receives a registration request of the new certificate center, responds to the registration request of the new certificate center, establishes cross authentication between the new certificate center and the registered certificate center, and generates trust chain data of the new certificate center. That is, for a new certificate center, a certain specific certificate center or several specific certificate centers are selected from registered certificate centers, and the specific certificate centers are used for issuing corresponding digital certificates for the new certificate centers so as to establish cross authentication between the new certificate centers and each specific certificate center, thereby realizing trust transfer from the registered certificate centers to the new certificate centers, and further adding the new certificate centers to trust chain data of each specific certificate center for issuing digital certificates for the new certificate centers, thereby generating trust chain data of the new certificate centers.
It should be noted that, when registering a new certificate center, the mutually trusted platform in this embodiment may randomly screen a specific certificate center for issuing a digital certificate for the new certificate center, or may issue a corresponding digital certificate for the new certificate center through the newly registered certificate center in the registered certificate centers according to the registration order, which is not limited in the trust transfer order between the registered certificate centers.
In this embodiment, after determining the certificate center to be mutually trusted, the self certificate issue condition of the certificate center to be mutually trusted may be analyzed and checked, and the trust chain data generated after the certificate centers to be mutually trusted are registered on the mutually trusted platform may be found, for example, the certificate centers A, B, C and D are registered on the mutually trusted platform, a is used as the first certificate center registered on the mutually trusted platform, and issues corresponding digital certificates for B and C, which represent a trust B and C, then C is used as D to issue corresponding digital certificates, represents C trust D, and if B is responsible for certificate management of the requesting party, D is used as the digital certificate corresponding to the to-be-authenticated party, then the trust chain data of B is used as B and D, and the trust chain data of D is used as a-C-D-to-be-authenticated party. Then, by analyzing the certificate centers and the trust transfer process contained in the trust chain data of each certificate center to be mutually trusted, a corresponding mutually trusted logic tree can be constructed, and at this time, each node of the mutually trusted logic tree can be the identification of the certificate center or the mobile terminal contained in the trust chain data of the certificate center to be mutually trusted, so that whether the digital certificate of the party to be verified is trusted can be judged according to the trust transfer process between the certificate centers to be mutually trusted represented in the mutually trusted logic tree.
S130, verifying whether the digital certificate of the party to be verified is trusted according to the mutual trust logic tree.
Specifically, the mutual trust logic tree represents a trust transfer process between certificate centers to be mutually trusted, so that whether the party to be authenticated is trusted can be firstly verified, when the party to be authenticated is trusted, whether the certificate center issuing the digital certificate for the party to be authenticated is trusted is continuously verified, if so, whether another certificate center issuing the digital certificate for the certificate center is trusted is continuously verified, and the process is sequentially circulated until whether the certificate center responsible for certificate management of a requester is trusted is verified, if the certificate center responsible for certificate management of the requester is determined to be trusted, the digital certificate of the party to be authenticated can be determined to be trusted for the requester, thereby realizing accurate verification of the digital certificate, and further ensuring the security of information transmission by accurately verifying the digital certificate.
It should be noted that, in this embodiment, the digital certificate of the party to be authenticated may be a mobile terminal certificate, and in this embodiment, the authentication mode of the mobile terminal certificate is mainly described.
According to the technical scheme provided by the embodiment, the certificate center to be mutually trusted is determined according to the verification request of the digital certificate of the party to be verified by the requesting party, then the trust chain data formed by the certificate center to be mutually trusted after the registration of the mutually trusted platform is utilized to construct a corresponding mutually trusted logic tree, each node of the mutually trusted logic tree can be the identifier of the certificate center or the mobile terminal contained in the trust chain data, and further the mutually trusted logic tree is adopted to verify whether the digital certificate of the party to be verified is trusted, so that accurate mutually trusted among different certificate centers to be mutually trusted is realized, the trust transfer condition of the different certificate centers is visually represented by the mutually trusted logic tree, the trust chains among the different certificate centers to be mutually trusted are not required to be checked continuously, and the convenience and the accuracy of digital certificate verification are improved; at this time, the digital certificate is accurately verified, so that the safety of information transmission is further ensured.
Example two
Fig. 2A is a flowchart of a method for verifying a digital certificate according to a second embodiment of the present invention. The embodiment of the invention is optimized based on the embodiment. Optionally, the digital certificate of the party to be authenticated may be a mobile terminal certificate, and this embodiment mainly explains a specific process of issuing the digital certificate for the mobile terminal adopted by the party to be authenticated and a specific authentication process of the digital certificate of the party to be authenticated in detail.
Specifically, referring to fig. 2A, the method of this embodiment may specifically include:
S210, determining a target certificate center which is selected by the party to be verified and is used for synchronously issuing the digital certificate in response to an application instruction of the digital certificate of the party to be verified.
Optionally, when the party to be verified applies for the digital certificate to the mutually trusted platform, the mutually trusted platform sends a corresponding application instruction, and at this time, the mutually trusted platform supports the party to be verified to apply for the corresponding digital certificate to the registered plurality of certificate centers respectively, that is, the mutually trusted platform is provided with a function of synchronously applying for the digital certificate issued by the plurality of certificate centers by one key. In this embodiment, the mutually trusted platform responds to an application instruction of a digital certificate of a party to be verified, and first analyzes the application instruction, so as to determine each target certificate center selected by the party to be verified and used for synchronously issuing the digital certificate for the party to be verified, so that corresponding digital certificates are respectively issued for the party to be verified by using trust chain data of each target certificate center after the mutually trusted platform is registered.
S220, synchronously issuing corresponding digital certificates for the party to be verified by utilizing trust chain data formed by each target certificate center after the registration of the mutually trusted platform and the equipment identification code of the mobile terminal where the party to be verified is located.
Optionally, after determining each target certificate center selected by the party to be verified and used for synchronously issuing the digital certificate for the party to be verified, trust chain data generated by each target certificate center after registering on a mutually trusted platform can be directly searched, and by analyzing hardware equipment information of a mobile terminal where the party to be verified is located, an equipment identification code of the party to be verified is determined, wherein the equipment identification code is used for indicating the equipment uniqueness of the party to be verified adopting the mobile terminal. Then, the trust chain data of each target certificate center can be utilized to synchronously issue corresponding digital certificates for the equipment identification codes of the to-be-verified parties, so that synchronous certificate issue for a plurality of certificate centers is realized.
It should be noted that, considering that the mobile terminal adopted by the party to be verified may be imitated, so that the device identification codes of different parties to be verified are repeated, so that the certificate center cannot distinguish the objects of certificate issue, and the problem that the mobile terminal applicable to the party to be verified represented by the digital certificate is not unique is caused.
That is, first, 64bit bits representing the device identification code of the party to be authenticated are divided into a plurality of parts in a manner of dividing the namespace as follows:
the 1 st bit occupies 1bit, and the value is always 0, and can be used as a symbol bit.
Bits 2 to 42 occupy 41 bits, which can be used as time stamp bits, and at this time, 41 bits can represent 2≡41 number, and represent millisecond, and then the available time period is (1L < < 41)/(1000L 360024 x 365) =69 years.
The 10bit occupied from the 43 rd bit to the 52 th bit can represent machine bits, namely 2+—10=1024 machines, wherein the first 4 bits in the 10bit can represent machine identification mapping, and the last 6 bits can represent working domains of the machines, so as to segment mobile terminals of different machine types and regions, and reduce the probability of equipment identification code repetition of the mobile terminals.
The last 12 bits can be used as the sequence number of the mobile terminal, and can represent 2≡12=4096 numbers.
Then, judging the timestamp, the machine number and the working region of the party to be verified by reading the hardware information of the mobile terminal used by the party to be verified, thereby setting the timestamp bit and the machine bit in each bit divided in the equipment identification code of the party to be verified; moreover, considering that the number of the mobile terminals is large, in this embodiment, a random algorithm may be used to generate the divided serial numbers in the device identifier codes of the party to be verified, instead of the serial numbers in the increment mode, so that corresponding device identifier codes are generated for multiple mobile terminals concurrently, and the generating efficiency of the device identifier codes is improved.
S230, determining a certificate center to be mutually trusted in response to a digital certificate verification request of a party to be verified by a requesting party.
S240, constructing a corresponding mutual trust logic tree according to trust chain data formed by a certificate center to be mutually trusted after the mutual trust platform is registered.
S250, determining public certificate centers of the requesting party and the party to be verified based on the mutual trust logic tree.
Optionally, in order to improve the efficiency of digital certificate verification, after the corresponding mutually trusted logic tree is constructed, the embodiment can intuitively find out the public certificate center which establishes the trust transfer relationship with the certificate centers corresponding to the requesting party and the party to be verified. For example, the mutually trusted platform has registered thereon the certificate centers A, B, C and D, a as the first certificate center registered to the mutually trusted platform, and issues corresponding digital certificates for B and C, indicating that a trusts B and C, and then C issues corresponding digital certificates for D, indicating that C trusts D, and if B is responsible for the certificate management of the requester, D issues corresponding digital certificates for the party to be authenticated, a mutually trusted logic tree as shown in fig. 2B may be constructed, and at this time, it may be determined that the public certificate centers of the requester and the party to be authenticated are a.
S260, verifying whether the public certificate center is trusted or not, and taking the trusted result of the public certificate center as the trusted result of the digital certificate of the party to be verified.
Optionally, because the certificate center responsible for the certificate management of the requesting party and the public certificate center have established a corresponding trust transfer relationship through the cross authentication mode between different certificate centers, that is to say, the certificate center responsible for the certificate management of the requesting party trusts the public certificate center, in order to improve the verification efficiency of the digital certificate, the embodiment can start from the party to be verified, firstly verify whether the party to be verified is trusted, continuously verify whether the certificate center issuing the digital certificate for the party to be verified is trusted when the party to be verified is trusted, continuously verify whether another certificate center issuing the digital certificate for the certificate center is trusted if the certificate center is trusted, and sequentially circulate until the certificate center is verified whether the public certificate center is trusted. Because the requesting party trusts the public certificate center, if the public certificate center is determined to be trusted, the digital certificate of the party to be verified can be directly determined to be trusted for the requesting party, so that accurate verification of the digital certificate is realized. In the cyclic verification process, if any certificate center is not trusted, the digital certificate of the party to be verified can be determined to be not trusted.
According to the technical scheme provided by the embodiment, the certificate center to be mutually trusted is determined according to the verification request of the digital certificate of the party to be verified by the requesting party, then the trust chain data formed by the certificate center to be mutually trusted after the registration of the mutually trusted platform is utilized to construct a corresponding mutually trusted logic tree, each node of the mutually trusted logic tree can be the identifier of the certificate center or the mobile terminal contained in the trust chain data, and further the mutually trusted logic tree is adopted to verify whether the digital certificate of the party to be verified is trusted, so that accurate mutually trusted among different certificate centers to be mutually trusted is realized, the mutually trusted logic tree visually represents the trust transfer condition of the different certificate centers, the trust chains among the different certificate centers to be mutually trusted do not need to be continuously checked, and the convenience and the accuracy of the verification of the mobile terminal certificate are improved; at this time, the security of the mobile terminal information transmission is further ensured by accurately verifying the mobile terminal certificate.
