摘　　要：普通的数字签名在有效保护用户隐私方面存在诸多不足,如对签名的抵赖和跟踪时有发生。针对上述问题,提出一种基于SM9算法的部分盲签名方案,部分是指签名消息包含用户的消息和其他有关信息,能够有效抵抗签名抵赖和跟踪,同时引入可信第三方来防止恶意用户对信息的篡改。通过实验结果和理论分析,证明了所提算法的安全性和高效性。Ordinary digital signatures have many deficiencies in effectively protecting users'privacy,and signature repudiation and tracking occur from time to time.In order to solve the above problems,a partial blind signature scheme based on the SM9 algorithm was proposed.Partially means that the signature message contains the user's message and other related information,so it can effectively resist signature repudiation and tracking,and introduce a trusted third party to prevent malicious users from tampering with information.Through experimental results and theoretical analysis,the security and efficiency of the proposed algorithm are proved.
