摘要

基于传统公钥密码系统的签名方案存在复杂的公钥证书管理问题,而基于身份密码系统的签名方案存在密钥托管的问题,针对此类问题,结合前向安全性提出一种基于无证书公钥密码系统的代理盲签名方案。经分析,新方案正确解决了证书管理问题和密钥托管问题,具有前向安全性、不可伪造性、盲性、不可追踪性,代理授权安全且具有不可否认性。
        The signature scheme based on traditional public key cryptosystem has complex public key certificate management problem,and the signature scheme based on identity cryptosystem has the problem of key escrow. For the above problems,a proxy blind signature scheme based on certificateless public key cryptosystem is proposed. The analysis results show that the new scheme is correct,can solve the problems of certificate management and key escrow,and has the advantages of forward security,unforgeability,blindness,non-traceability,safe proxy authorization and non-repudiation.
