Abstract： In order to solve the problems of cumbersome user authentication process, insecure identity information, and vulnerability of authentication system in traditional identity authentication, a distributed identity authentication method based on alliance chain is proposed, which uses the decentralization of blockchain and is not easy to tamper with. Features and asymmetric encryption methods are used to improve the security and stability of the user identity authentication system. On this basis, a distributed authentication scheme was designed, including identity registration and authentication processes, and the core consensus algorithm PBFT was optimized to improve authentication efficiency. The experimental results show that the blockchain-based authentication mechanism and optimized PBFT algorithm improve the reliability of the authentication system and ensure its efficiency.
