摘要
通过对签名者不可抵赖性缺陷的分析和研究,将公钥密码体制和对称密码体制相结合,提出了一个基于冗余函数、收发双发都不能否认的具有消息恢复功能的盲签名方案,并对该方案的正确性、可靠性和安全性进行了分析.该方案保证了通信的公平公正性,保密性好,特别适合于商业领域的信息交互.
By defect analysis and research on signer＇s non-repudiation,combining with the public-key cryptosystem and symmetric cryptosystem,an improved blind signature scheme based on redundancy function with message recovery is proposed.Furthermore,the correctness,reliability and security of the scheme are analyzed.The results show that the scheme can guarantee the fairness and security in the communication,and is suitable for the information interaction in commercial areas especially.
