分析了现有的以系统时钟基本同步为前提的鉴别协议中存在的安全问题，指出了产生该问题的原因.在此基础上，提出了一种新的无须系统时钟同步的鉴别协议.新协议使用一种简便易行的解决方案，采用第三方时间标记，从而消除了系统时钟不同步所带来的影响，清除了指出的安全漏洞.最后，分析了新协议的优点和不足.

This paper analyzes the weakness of the authentication protocols based on the supposition that the system′s clocks are synchronous, gives the reason resulting in the weakness, and presents a new authentication protocol. A simple method with the third part timestamp to get rid of the effects of system clocks′ asynchronization and to resolve the problem in this authentication is presented. The advantages and disadvantages of the new authentication protocol are also pointed out.
