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.
