多服务器体系结构中基于动态身份的认证协议的弱点

Weaknesses of a dynamic identity based authentication protocol for multi-server architecture

Weiwei Han

摘要:

最近,Li等人提出了一种适用于多服务器体系结构的基于动态身份的认证协议。他们声称他们的协议是安全的,可以抵御各种攻击。但我们在协议中发现了一些安全漏洞。因此,目前的文件表明,李等。的协议容易受到重放攻击、密码猜测攻击和伪装攻击。

英文摘要:

Recently, Li et al. proposed a dynamic identity based authentication protocol for multi-server architecture. They claimed their protocol is secure and can withstand various attacks. But we found some security loopholes in the protocol. Accordingly, the current paper demonstrates that Li et al.'s protocol is vulnerable to the replay attack, the password guessing attack and the masquerade attack.
