Mobile IPv6 Security

Mobile IPv6 provides global mobility and location management support for the IPv6 network layer protocol. The design of Mobile IPv6 incorporates security features that differ significantly from its predecessor, Mobile IPv4. Some of the new security features are intended to counter new threats raised by route optimization, while others align Mobile IPv6 security more closely with basic IPv6 security mechanisms. In this paper, we outline the security threats to Mobile IPv6 and describe how the security features of the Mobile IPv6 protocol mitigate them.
