Abstract: Focused on the mobile Web Services’ security issues, this paper proposes the application layer’s security assurance by using XML encryption and signature. This method affectes the system’s efficiency. It achieves an optimized implementation by using WAP’s optimized encoding and proprietary transmission protocol. Experiments considering the aspects of dealing time and spending show that, the efficiency is greatly improved and the security is not affected.
