摘　　要：提出了基于Diff-Hellman的改进Yang-Shieh智能卡认证协议(DHYS),并采用串空间理论形式化证明了DHYS的安全性.DHYS在增强Yang-Shieh认证协议安全性的同时,无任何附加限制,保留了原Yang-Shieh协议的全部优点.Yang-Shieh authentication scheme is vulnerable to malicious attacks.In this paper,the authors proposed a DH-based improvement on Yang-Shieh authentication scheme.At first,the authors formally analyzed YangeShieh s password authentication scheme on the basis of authentication tests to disclose the insecurity of the scheme.Then it was proposed their improvement on YangShieh s authentication scheme based on Diff-Hellman,which can withstand existing attacks.Finally,the authors also formally analyzed the improve...
