Abstract : Mobile IP is a protocol, developed by the Mobile IP Internet Engineering Task Force (IETF) working group that allows the delivery of the packets to mobile nodes when they moves to a new network based on its old IP address. Due to the increase of fraudulent activities in the current world, wanted level for the security feature is increased. But usage of security must be provided without compromising the efficiency. In this paper a secure and efficient registration protocol is proposed for IP Mobility, as the security feature adopted is directly proportional to the registration delay time. This protocol provides security between the mobility agents using AES and HMAC algorithm with reduction in registration time. It also secures messages between a mobile node and agents, and analyses the various protocols in the Mobile IP environment with this approach, based on different features. Based on the numerical results, the proposed protocol outfits the existing protocol based on the security issues and registration competency. Here, an attempt has been made to simulate the Mobile IP scenario for the proposed protocol with the use of NS-2 [5] network simulator. Copyright 2012 ACM.
