A Secure Hierarchical Identify Authentication Scheme in Mobile IPv6 Networks

To MIPv6 networks, Identify authentication is an important part of the network security. In this paper, we proposed a secure identify authentication scheme. 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. Based on the combined public key algorithm and double private key, a hierarchical signature and verification scheme is designed in one round mutual authentication. Theoretical analysis and numerical result s show that proposed scheme is more effective in reducing total authentication and handoff delay and the signaling overhead than relative schemes. Security analysis shows, based on the security of CPK algorithm and IBS, the proposed scheme is sufficient for private key privacy, signature unforgeability in mobile IPv6 networks.
