An optimized and secure BUTE – binding update using twofold encryption for next generation IP mobility

Abstract

The mobile Internet Protocol (IP) is a mobility based communication protocol that provides guidelines for the routing of mobile nodes in a network. The mobile IP manipulates IP addresses as a natural identifier for each mobile communicant. Here, each mobile device recognizes itself via two IP addresses: a home-of address and a care-of address. Owing to the mobility nature of the these devices, the location update of their current care-of address plays a vital role in receiving continuous services without interference. Many investigations have been explored on the location update of mobile devices along with the security and computation issues. However, the efforts on the security services have not received much attention in these investigations. Consequently, there is an increasing need for optimized binding update that balances security and efficiency. In this paper, a new Binding Update using Twofold Encryption (BUTE) is proposed, for balancing both security and efficiency of binding update for IPv6 mobility. It exhibits the alleviation of the attacks such as rerun, man-in-the-middle, false binding update and denial-of-service. The proposed BUTE is simulated using network simulator-2 and the experimental results are analyzed. Also, it is validated for security attributes using Automated Validation of Internet Security Protocols and Applications (AVISPA) – a security tool. Finally, the numerical results reveal that the proposed BUTE provides a significant reduction in communication cost and binding update delays.
