Abstract: This paper puts forward a new web service authentication key agreement protocol in wireless network, which provides privacy password, secure mutual authentication and key secret. The protocol combines techniques of challenge response protocols with SEKE protocols，and uses the Diffie-Hellman protocol in the process of key agreement. At the same time, secure property, computational and communication performance are analyzed.

摘要： 提出了一种新的无线环境下的Web服务身份认证密钥协商协议，可以提供口令私密性、通信双方认证性和私钥的秘密性。该协议是在挑战响应协议和SEKE协议的基础上提出来的，在密钥设计过程中采用了Diffie-Hellman协议原理。最后，对协议的安全属性，协议的计算代价和通信代价等性能属性分别进行了分析。
