Ticket Based Pre-authentication Method for Trusted Nodes in Proxy Mobile IPv6 Domain

摘要

Inter-working among heterogeneous mobile broadband net-works requires secure handover. In this paper, we propose a ticket-based pre-authentication scheme for trust nodes in the proxy mobile ipv6 domain, where security materials are reused for fast authentication dur-ing handover among wireless access networks. The security of the scheme is verified by the formal logic of SVO. It is also proved to outperform tra-ditional authentication method in reducing the handover authentication latency and authentication cost.
