Security chip based on PUF and zero knowledge proof, application method, system and medium

Abstract

The invention discloses a security chip based on PUF and zero knowledge proof, an application method, a system and a medium. The security chip based on PUF and zero knowledge proof comprises a PUF circuit module, a ChipID generation circuit module, a zero knowledge proof circuit module and a main control module. The zero knowledge proof circuit module comprises a first execution circuit used for generating a publicable zero knowledge identification number PID and a second execution circuit used for generating a proof code P. An identity authentication application method comprises the step of realizing the identity authentication method based on the lightweight security chip based on the security chip. The identity authentication method does not need a complex interactive protocol. The request end and the server end only need to execute zero knowledge proof calculation. Compared with a digital signature and authentication method based on a public key cryptographic algorithm, the identity authentication method is simpler and has the advantages of good universality, high security, low authentication overhead, simple authentication process and the like.

Description

technical field [0001] The present invention relates to the technical fields of integrated circuit design and information security, in particular to a security chip based on PUF (Physically Unreproducible Function) and zero-knowledge proof, and an application method, system and medium. Background technique [0002] With the rapid development of information technology and the popularization and application of digital and intelligent information systems, the security issues of information systems have become increasingly prominent. The safe and credible identity authentication of the access client by the server system has become the basis of all information system security. Users and terminals can obtain corresponding services from the server only after confirming the legitimacy of their identities. At present, the identity authentication is mainly the identity authentication of the user and the information equipment operated by the user. With the rapid development of the Inte...

Problems solved by technology

[0005] As mentioned above, the existing authentication methods often require multiple rounds of interaction between the authentication requester and the authentication server to complete the authentication, which not only cannot meet the security authentication requirements of the IoT environment, but also increases security risks due to round-trip interactions. , at the same time authentication takes longer, more power consumption is required to complete the authentication, and the user experience is not good
