Mobile IP (MIP) has been paid a lot of attention as a good candidate to provide such global mobility among heterogeneous networks. And, IPv6 incorporates the mobility into its extended function which is referred to as mobile IPv6 (MIPv6). On the other hand, authentication, authorization and accounting (AAA) service now plays an important role in many networks. Considering the future popularity of MIPv6 in many networks, investigating the MIPv6 architecture in a way that the fast handoff is well supported in the presence of AAA is desirable. In this paper, we propose a new authentication procedure for MIPv6based networks where the original procedures of both fast handoff and AAA are still preserved to interoperate with other networks. The proposed temporary authentication allows the roaming user to continue communication activit...
