Abstract: Nowadays, vehicular ad hoc networks (VANETs) have become a more interesting research area. A high number of safety, traffic management and even comfort applications have been developed to secure driving and make travellers satisfied. This evolution opens up a vast area of research in several fields. Specifically in the security domain, huge researches are proposed to give new approaches and mechanisms of security. VANETs as wireless and mobile networks require the implementation of secure and lightweight algorithms dealing with its critical characteristics to face different attacks. In this paper, we propose a novel approach of security to face some known attacks. We design a model of communication that combines digital signature, message authentication mechanisms, to securely generate the secret key, and thereby, achieve integrity, confidentiality, session key security and non-repudiation. In the end, we prove the security of our model by analysing different cases of attacks.
