Executive Summary

On the basis of comprehensive study of trusted computing technology and the threats to 3G network, the architecture of trusted mobile platform based on mobile trusted module is proposed, and a DAA-based key management and a trusted computing based access mechanism for 3G network are designed. Furthermore, a predicate logic based formal analysis method is also proposed. With DAA mechanism, user privacy is protected and the bottleneck problem of centralized CA is avoided. The proposed MTM-based trusted access mechanism focuses on not only the authentication of mobile user, but also the healthy status of the mobile user.
