A Secure Route Optimization Mechanism for Expressive Internet Architecture (XIA) Mobility.

Motivated by the natural features of ID/location decoupling and self-certifying in Expressive Internet Architecture (XIA), we designs a secure mechanism to protect the binding update message for route optimization in XIA mobility. The proposed mechanism protects the vulnerabilities by combining identity authentication and reachability verification. Meanwhile, in order to reduce the signaling overhead in the following movement of the mobile node, we divide the routing optimization procedure into two phases and replace the public-key cryptography with hashing operation to authenticate the subsequent binding update messages. The analysis shows that our protocol is efficient, especially for nodes that move frequently and the movement can be predicted.
