A Security Registration Based on IPSec for Mobile IPv6 Fast Handoff

At present, many studies focus on the efficiency of handoff among different networks, while research on how to maintain the safety during registration process of handoff is not enough. Unfortunately, mobile node is vulnerable to various security threats and attacks when handover for being lack of protection. A security scheme based on the IPSec protocol which was combined with fast handoff signaling was given in this paper. The mutual handover authentication between mobile nodes and access routers was obtained through improved handoff signaling, and IPSec security association was used to protect the handoff process without lowering its efficiency.
