Secure Mobile IP Registration Scheme with AAA from Parings to Reduce Registration Delay

摘要

A key problem in the Mobile IP registration with Authentication, Authorization and Accounting (AAA) is how to minimize the registration delay while improve the security. This paper solves this problem by the noninteractive authentication from pairings in the identitybased cryptography. The main idea behind our scheme is to minimize both the on-line pairing operation time and the inter-domain communication round trip time based on the dynamic one-way authentication key and the challenge generated in the foreign network. Analysis shows that the registration delay is reduced from 420.201ms of the basic pairing-based registration scheme to the current 23.766ms while the improved security attributes including mutual tri-partite authentication, local key generation, anti-replay attack and user privacy are provided in our scheme.
