So the structure, principle, security infrastructure, application model and environment of WPKI are described in detail. Then the mobile E-business security model based on WPKI Technology is proposed in this paper. It will analyze and demonstrate how the WPKI technology can provide the security services to mobile E-business with similar security requirements and provide the reader with a high level technical application of the WPKI technology. And a application system provided an excellent example for demonstrating the effectiveness, and the secrecy, identity authentication and non repudiation are studied and analyzed.
