VANET (Vehicular Ad hoc NETwork) is a self-organized network formed by connecting vehicles. It can be used in several cases such as internet connection to obtain real time news, traffic, and weather reports, etc. However, the main applications of VANET are oriented to safety issues (e.g., traffic services, alarm and warning messaging). In such context, a security problem can have disastrous consequences. In fact, an attacker can be tempted to redirect all vehicles to a given location for malicious reasons. Hence, it is necessary to make sure that exchanged packets are not inserted or modified by the attacker. The main contribution of this paper is then, the proposition of a secure communication scheme for safety message exchange in VANET.
