Enhanced dual authentication and key management scheme for data authentication in vehicular ad hoc network

Abstract

Vehicular Ad hoc Network has vehicles communicating with processing units. The end devices need to be secured for transmitting data in authenticated mode. However there are challenges including intrusion, routing overhead and delayed communication. Since vehicles are exposed to attacks, security mechanisms are to be deployed. In this article, a mechanism for enhancing security in communication using elliptical curve cryptography (ECC) and Diffie–Hellman key exchange protocol with Bilinear map mechanism is employed. The proposed enhanced dual authentication (EDA) with key management scheme has been compared with dual authentication and results have been presented. The performance parameters evaluated are delay, drop count, dropping ratio, jitter, normalized routing overhead, packet delivery ratio, and throughput. From results, it can be inferred that EDA model increases the amount of trust in terms of integrity and authentication.
