摘要： 强不可伪造性和对安全信道依赖性的分析是对LKK代理签名方案安全性分析的重要内容之一。对文献[6-8]中的改进的LKK代理签名方案进行安全性分析,指出文献[6,7]中的方案仍存在缺陷并给出攻击方法,指出文献[8]中方案是一个具有强不可伪造性的不需要安全信道的方案。
Abstract: The analysis of the property of the strong unforgeability and the necessity of a secure channel is one of the important content for the security analysis of the LKK proxy signature scheme.In this paper,we present a security analysis of some improved LKK proxy signature schemes,proposed in[6-8].We point out the schemes,proposed in[6,7],still have weakness and present the attack methods to them.And we point out the scheme,proposed in [8],can keep the property of the strong unforgeability and does not need the secure channel.
