Abstract

The embodiment of the invention discloses an identity authentication method and device. The method comprises the following steps: sending a vehicle system decentralized identity and a template request to a cloud platform; the cloud platform obtaining a vehicle system public key according to the vehicle system decentralized identity; receiving return information of the cloud platform, wherein the return information comprises a decentralized identity of the cloud platform, a template framework and a random number; decrypting the returned information by using a vehicle system private key, filling information in the template framework, encrypting the random number and the filled template by using a cloud platform public key, and sending the encrypted random number and filled template to the cloud platform; decrypting by the cloud platform by using the cloud platform private key, and determining an identity authentication result according to the consistency of the random number and the random number stored in the cloud platform; and receiving an identity authentication result returned by the cloud platform. By implementing the technical scheme provided by the invention, the effect of improving the security of the information can be achieved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to an identity authentication method and device. Background technique [0002] With the rapid development of science and technology, the transmission of information content tends to adopt the form of the Internet more and more. However, information transmission on the Internet often has certain risks. For example, hackers maliciously use false identities to obtain confidential information, which greatly affects the information security of users. The way people currently use is mainly to encrypt the content of the information and interact with the communication counterparty. This will cause a problem, that is, if the encryption and decryption method is cracked, the security of the information cannot be guaranteed. Contents of the invention [0003] Embodiments of the present application provide an identity authentication method and device, which ...
