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

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 includes a PUF circuit module, a ChipID generating circuit module, a zero-knowledge proof circuit module and The main control module, the zero-knowledge proof circuit module includes a first execution circuit for generating a publicly available zero-knowledge identification number PID and a second execution circuit for generating a proof code P; An identity authentication method for an order-of-magnitude security chip. This identity authentication method does not require complex interactive protocols. The requester and server only need to perform zero-knowledge proof calculations. Compared with digital signatures and authentication methods based on public key cryptography algorithms, they are simpler. It has the advantages of good versatility, high security, low authentication overhead, and simple authentication process.

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
