Building up Trusted Identity Management in Mobile Heterogeneous Environment

Mobile Internet enables mobile users to access Internet services through mobile networks. Currently, cellular networks are converging with various wireless networks, e.g., WLAN, MANET, which forms a heterogeneous mobile environment. In such environment, it has been a big challenge for mobile operators and mobile service providers to offer seamless roaming and services among the networks. Previous work on solving the problem falls in specific network circumstance, which cannot be easily and widely applied in the heterogeneous environment. In this paper, we foresee the future of mobile networks into mobile cloud environment. Thus, we propose a generic and flexible solution based on cloud computing technology that can achieve various benefits, such as robustness, high availability, and so on. We present the architecture and procedures for building up the trusted identity management to achieve seamless roaming.
