Identity authentication serves as the primary line of defense for safeguarding user data,providing crucial assurance for the security of user information.Existing identity authentication methods rely on authoritative centers such as Credential Service Providers(CSP),trusting their self-control and security capabilities.However,authoritative centers possess absolute control over identity,and any failure in these centers may pose security risks to information.Considering this,we propose an identity generation and authentication mechanism based on multi-PUF modules,introducing PUF hardware fingerprints into the authentication process and designing a decentralized identity authentication mechanism.Physical Unclonable Function(PUF)describes a physically unique and tamper-resistant function widely applied in the field of identity authentication.However,PUFs are susceptible to environmental influences,leading to potential failures.Existing PUF-based identity authentication methods have not provided tolerance solutions for PUF chip failures.We propose a solution to enhance the usability of identity authentication mechanisms by utilizing a correlated approach with multiple PUF modules.Finally,we discuss and demonstrate the proposed mechanism in terms of security,feasibility,and reliability.
