Abstract

With the application of new technologies such as Internet of Things and big data in smart grid industry, new power systems based on new energy sources have emerged in response to the call of “Peak carbon, carbon neutrality.” The power grid enterprise concentrates the data assets and business access to the data external service, which needs to connect a large number of data sources. Ensuring the authenticity of the data without tampering becomes a big challenge. The power system adopts the identity authentication mechanism to resist the security attack and protect the sensitive data. However, in the process of user authentication, the sending of real identity information will lead to the reduction of system privacy, which is easy to cause the leakage of sensitive data. This paper proposes an anonymous authentication mechanism based on zero-knowledge proof for power system, which authenticates the server without revealing the identity. This mechanism uses zero-knowledge proof algorithm to design an anonymous authentication protocol framework, which consists of three stages: registration, mutual authentication and revocation. In this method, anonymous certificate and elliptic curve encryption technology are used to realize the anonymity and authenticity of users. The mechanism effectively protects the user's real identity information and maintains the sensitive data in the power system.
