It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a schematic structural diagram of an identity authentication system provided in an embodiment of the present application, where the embodiment is applicable to a case of information interaction, and the system may be implemented by software and/or hardware.
As shown in fig. 1, the identity authentication system includes: vehicle system 110 and cloud platform 120;
the vehicle system 110 is configured to send a vehicle system decentralized identity and a template request to the cloud platform 120;
the cloud platform 120 is configured to obtain a public key of the vehicle system according to the decentralized identity of the vehicle system; and send return information to the vehicle system 110, the return information including cloud platform decentralized identity, template framework and random number; wherein the return information is encrypted by a vehicle system public key;
the vehicle system 110 decrypts the returned information by using a vehicle system private key, fills information in the template framework, encrypts the random number and the filled template by using a cloud platform public key, and sends the encrypted random number and the filled template to the cloud platform 120;
the cloud platform 120 decrypts the data using the cloud platform private key, determines an identity authentication result according to the consistency between the random number and the random number stored in the cloud platform, and sends the identity authentication result to the vehicle system 110.
The vehicle system may be a system that manages vehicle information, and may be, for example, a vehicle manufacturer. Before the vehicle system sends the decentralized identity, the public key of the local terminal can be linked up and uploaded to the block chain, and then the decentralized identity can be obtained and sent to the cloud platform. In addition, the vehicle system may send a template request, where the template request may be a request to the cloud platform for a basic information template, a security information template, and the like. The template request may be used to obtain a template in a format corresponding to the request, which may be populated with information by the vehicle system. Thus, the information can be matched to the decentralized identity of the vehicle. After the vehicle system decentralized identity and the template request are sent, the cloud platform can obtain the public key of the vehicle system according to the vehicle system decentralized identity. The public key of the vehicle system may be a key used for interacting with the vehicle, for example, the information sent to the vehicle system is encrypted by the public key of the vehicle system, and the vehicle system itself decrypts the information by using its private key, so that the encrypted transmission of the information can be completed.
And receiving return information of the cloud platform, wherein the return information can comprise a cloud platform decentralized identity, a template framework returned according to the template request and a random number randomly generated by the cloud platform. Wherein the return information may be encrypted by the vehicle system public key. The method has the advantages that the random number can be provided to increase the cracking difficulty of the identity authentication process, the public key of the vehicle system is used for encryption, only one party with the private key of the vehicle system can decrypt the public key, and therefore the safety of the whole authentication process can be improved.
After receiving the return information, the vehicle system can decrypt the return information by using the private key, fill the obtained template framework with the information, encrypt the random number and the content of the filled template through the cloud platform public key, and send the encrypted random number and the content of the filled template to the cloud platform. Wherein, the transmitted information can be used as identity authentication information. After the cloud platform receives the information, the cloud platform private key can be used for decryption, if the decryption is unsuccessful, the result shows that the encryption public key of the opposite side is incorrect, and the authentication fails. If the decryption is successful, the random number in the encrypted random number is further identified, because the random number is generated by one end of the cloud platform and has uniqueness, if the random number is different from the random number stored when the cloud platform is locally generated, the identity authentication fails, which indicates that the opposite party does not take the correct random number, and if the verification is the same, the identity authentication is successful.
After determining the authentication result, the result may be returned to the vehicle system, for example, if the authentication is successful, a result of successful authentication is returned, and if the authentication is failed, a result of failed authentication is returned.
According to the technical scheme provided by the embodiment of the application, the system comprises: a vehicle system and a cloud platform; the vehicle system is used for sending a vehicle system decentralized identity and a template request to the cloud platform; the cloud platform is used for acquiring a public key of the vehicle system according to the decentralized identity of the vehicle system; sending return information to the vehicle system, wherein the return information comprises cloud platform decentralized identity, a template frame and a random number; wherein the return information is encrypted by a vehicle system public key; the vehicle system decrypts the returned information by using a vehicle system private key, fills information in the template framework, encrypts the random number and the filled template by using a cloud platform public key, and sends the encrypted random number and the filled template to a cloud platform; and the cloud platform decrypts by using a cloud platform private key, determines an identity authentication result according to the consistency of the random number and the random number stored by the cloud platform, and sends the identity authentication result to the vehicle system. By adopting the technical scheme provided by the application, the effect of improving the safety of the information can be realized.
On the basis of the technical solutions, optionally, after the random number and the filled template are encrypted by using the cloud platform public key and sent to the cloud platform, the cloud platform stores the vehicle system identity and the information in the template correspondingly after the identity authentication is successful. After the cloud platform is successfully authenticated, the identity of the vehicle system and the information in the template can be correspondingly stored, for example, an association relationship can be set between the identity of the vehicle system and the information in the template, and when other systems need to acquire some information of the vehicle system, the corresponding information in the template of the vehicle system can be provided through the cloud platform. The method has the advantages that the template can be set and bound with the template, and the problems that in the prior art, the information needing to access the vehicle system at each time needs to send a request to the vehicle system independently, and no cloud platform is used as an intermediate carrier, so that the system sending the request cannot be subjected to effective identity authentication are solved.
On the basis of the above technical solutions, optionally, the vehicle system decentralized identity is generated by chaining a public key of the vehicle system. In the technical scheme, the vehicle system can generate the decentralized identity of the vehicle by chaining the public key of the vehicle system. The cloud platform can acquire the public key of the vehicle system on the chain by decentralized identity, and further can perform identity authentication with the vehicle system. The technical scheme has the advantages that the distributed storage and data security effects in the block chain technology can be utilized, and the security guarantee is brought for the subsequent identity authentication and information interaction work.
On the basis of the above technical solutions, optionally, the information in the template includes at least two disclosure levels, where each disclosure level corresponds to one permission requirement. Wherein, the information in the template can be divided into different disclosure levels, for example, three disclosure levels of 1, 2 and 3 are included, wherein, the level 1 is the lowest level, the level 3 is the highest level, and each level has different authority requirements. For example, the insurance system meets the authority requirements of level 1 and level 2, and when the insurance system accesses the template of the vehicle system, the information of the disclosure levels of level 1 and level 2 can be obtained through the access authority. If the vehicle management system meets the authority requirements of all three levels, the display of the disclosure information of all three levels can be obtained through the access authority. According to the technical scheme, the information in the template is displayed according to different disclosure levels, so that the safety of data information can be improved, the requirements of different access parties can be met through one template, and different templates do not need to be created for each access party.
The decentralized identity of the vehicle system can be equivalent to a storage address of a public key on a chain, and the public key stored on the block chain of the vehicle system can be acquired through the decentralized identity.
The random number in the return message may be generated by the cloud platform after receiving the request, and the template framework may be provided according to the template request. In addition, the return information further includes a cloud platform decentralized identity, and the cloud platform decentralized identity may be obtained by chaining the cloud platform public key by the cloud platform.
The returned information can be subjected to inter-encryption through the public key of the vehicle system, so that only the vehicle system can decrypt the returned information through the private key of the vehicle system, and the returned information can be effectively prevented from being intercepted. And after the returned information is decrypted by using the private key of the vehicle system, the vehicle system fills the information in the template frame, encrypts the random number and the filled template by using the public key of the cloud platform and sends the encrypted random number and the filled template to the cloud platform.
The cloud platform can decrypt through the private key, and compares the random number obtained by decryption with the locally stored random number, if the random number is consistent, the identity authentication is successful, and if the random number is inconsistent, the identity authentication is failed. After the identity authentication result is obtained, the identity authentication result can be returned to the vehicle system.
On the basis of the above technical solutions, optionally, after the identity authentication result is determined, if the identity authentication is successful, the vehicle system identity and the information in the template are correspondingly stored. After the identity authentication is successful, the vehicle system identity and the information in the template may be correspondingly stored, for example, stored in an associated manner. Namely, after the vehicle system is located by the access party, the specific content of the information filled in the template by the vehicle system can be obtained according to the incidence relation between the identity of the vehicle system and the information in the template, so that the information access efficiency can be improved.
On the basis of the foregoing technical solutions, optionally, the cloud platform decentralized identity is generated by chaining a public key of the cloud platform. The cloud platform decentralized identity can be obtained through public key chaining of the cloud platform, and then the public key of the cloud platform can be obtained through the decentralized identity. Through the arrangement, the advantages of distributed storage of the block chain and information safety can be utilized, and therefore the safety of information interaction between the cloud platform and the vehicle system is guaranteed.
On the basis of the above technical solutions, optionally, after the vehicle system identity is stored in correspondence with the information in the template, the system further includes: acquiring disclosure levels of information in a template, wherein each disclosure level corresponds to an authority requirement; and if a viewing request of the information in the template is received, determining the disclosure level displayed to the requester according to the matching result of the right item of the requester and the right requirement of the disclosure level.
Wherein after determining the disclosure levels of the information in the template, the entitlement requirements for each level may be determined. When a viewing request is received, whether the authority of the requester has a matching relation with the authority requirement or not is determined, and the requester can specifically have the viewing authority to one or more levels of information, so that the content disclosed by the requester is determined. According to the technical scheme, different information contents can be disclosed for different requesters according to the authority of the requesters, so that the information safety of a vehicle system can be ensured, different information templates do not need to be set for a plurality of requesters, and the operation is simplified.
