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
