摘　　要：为了解决传统身份认证中用户认证流程繁琐、身份信息不安全、认证系统易受攻击等问题,提出了一种基于联盟链的分布式身份认证方法,利用区块链的去中心化、不易篡改的特性和非对称加密等方法,提高用户身份认证系统的安全性和稳定性。在此基础上设计了分布式认证方案,包括身份注册和认证流程,并对其中的核心共识算法PBFT进行了优化,以提高认证效率。实验结果表明,基于区块链的认证机制和优化的PBFT算法提升了认证系统的可靠性并保证了其高效性。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.
