两个前向安全代理盲签名方案的分析与改进
Analysis and Improvement of Two Forward Secure Proxy Blind Signature Schemes
摘要
Abstract
Through the security analysis of two forward secure proxy blind signature schemes proposed by Zhou Ping et .al ,it is pointed out that the two schemes don't resist the original signer's forgery attack ,and they have not the character‐istic of forward security at all .To solve the above problems ,two improved schemes are presented .The analysis results show that they have the features of resisting forging attack and true forward security ,especially ,the improved signature 2 has the property of backward security ,which is a strong forward secure signature .关键词
