Improvement of Authentication Test in Application
认证测试方法在应用中出现的问题及改进

In application,when multiple form transformations of key atomic value occur,there should be multiple au- thentication tests.With the conception of Key Component,a new method called Multiple Authentication Test is pres- ented.Then the Woo-Lam protocol is redesigned and improved by this method.Through two"challenge-response"runs,the role asymmetry and identity authentication of participants are ensured,not only avoiding the flaw in the pro- tocol improved by Authentication Test,but also avoiding two replay attacks in the protocol improved by informal prin- ciples and BSW logic.
