Trust Model Based on TPM for Network Mobility

Under mobile environment, the third part trusted may not be reached at any time. Moreover, there exist attacks on overall performance and availability of mobile networks caused by deceit of legal users and compromised platforms. In this paper, trust model composed of identity authentication, platform integrity attestation and user behavior evaluation is raised for network mobility (NEMO). Where, identity authentication guarantees the authenticity of IP address, user and platform. Security analysis shows that the trust model blocks most of existing threats to NEMO by rejecting illegal users and problem terminals, and as well reduces negative impacts of legal users´ malicious acts on NEMO performance and availability by behavior evaluation and access router selection.
