摘　　要：SM9算法是我国现有商用密码体系中相对安全、高效的密码体制。为充分发挥SM9算法的优势,优化传统身份认证技术方案所存在的负面问题,进一步优化线上交易、企业工作交接等场景的隐私性与安全性。该研究采用理论研究与实践论证的方式,在对SM9算法的概念进行解析后,设定一种基于区块链的去中心化身份认证技术方案,重点分析该方案的身份认证模式及密钥管理方案,并在最后论证该方案的安全性及运行效率。该互联网身份认证技术方案在安全性与效率性方面具备一定的优势,能够满足当前社会环境中绝大部分的线上对接身份认证需求,且区块链数据存在不可篡改的形式,因此,在区块链技术以及SM9算法的双向加持下,该互联网身份认证技术方案的安全性得到进一步优化,具备深入研究与推广的价值。SM9 algorithm is a relatively secure and efficient cryptosystem in the existing commercial cryptosystem in China.In order to give full play to the advantages of SM9 algorithm,optimize the negative problems of traditional identity authentication technology,and further optimize the privacy and security of online transactions,enterprise work handover and other scenarios.This research adopts the way of theoretical research and practical demonstration.After analyzing the concept of SM9 algorithm,this paper sets up a decentralized identity authentication scheme based on block chain,focuses on the identity authentication mode and secret key management scheme of the scheme,and finally demonstrates the security and operation efficiency of the scheme.However,the Internet identity authentication scheme has certain advantages in terms of security and efficiency,and can meet most of the online docking authentication needs in the current social environment,and the block chain data has an untampered form.Therefore,under the two-way support of block chain technology and SM9 algorithm,the security of the Internet identity authentication scheme has been further optimized,with the value of in-depth research and promotion.
