Abstract : Mobile Internet Protocol version 6 (MIPv6) maintains convergence for communication of mobile technologies with the ability to change their IP address. In MIPv6, a mobile device transmits location update messages which informs the current care-of address to its home agent indirectly, or to correspondent node directly, is termed as binding update. Security issues in MIPv6 are of vital significance, and the binding update messages must be secured against any malicious attacks that might attempt to get unauthorized access from the participating entities. This paper improves binding update scheme using optimal asymmetric encryption, which enhances security without relying on a third party. The proposed scheme achieves mutual authentication between the communicants and significant reduction in computational cost. The scheme is simulated and validated using the security tool AVISPA. Also, mitigation for various malicious attacks, such as replay attack, man-in-the-middle attack, and false binding update attack, have been addressed.
