Improving Security and Efficiency in Mobile IP Networks
The emergence of mobile devices or mobile nodes allows the users to access the network when they are on the move. As users move frequently from one network to another network a new IP address is assigned to the mobile node every time when it visits a new network. The change in IP address is informed to other nodes is dealt by Mobile IP. The ID based protocol minimizes the registration delay through a minimal usage of the IDentity (ID)-based signature scheme that eliminates expensive pairing operations. The proposed protocol takes, advantages of self-certified key for PKI(Public Key Infrastructure). To provide explicit authentication for self-certified key, the authors propose to use a concept of self-certificate.
