A Secure Hierarchical Identify Authentication Scheme Combining Trust Mechanism in Mobile IPv6 Networks

During the last few years, it has become more and more conpeling in mobile applications, mobile IPv6 technology is convenient, but also produces a series of security compromise. Identify authentication is an important part of the network security. In this paper, we proposed a secure identify authentication scheme combining reputation mechanism, which considers inters domain trust relationship between mobile node home domain and the access domain in the pre-handoff procedure and realizes effective mutual authentication between mobile node(MN) and the access domain. A dynamic reputation maintenance mechanism for inter domain relationship is also designed. Based SMC signature, a hierarchical signature and verification scheme is designed in one round mutual authentication. Theoretical analysis and numerical results show that proposed scheme is more effective in reducing total authentication and handoff delay and the signaling overhead than relative schemes. Security analysis shows, basing on the security of SMC-IBS, the proposed scheme is sufficient for private key privacy, signature unforgeability. Moreover, our scheme first provide public key revocation and key escrow problem in mobile IPv6 networks’ access authentication.
