Abstract :

The security of Vehicular Ad hoc Networks (VANETs) is receiving a significant amount of attention in the field of wireless mobile networking because VANETs are vulnerable to malicious attacks. A man-in-the-middle attack is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other. The vehicular nodes communicate with other vehicle nodes and share the messages. By receiving GPS signals, the device can determine its current location and then find the geographically shortest route to a certain destination based on a local map database. A number of secure authentication schemes based on asymmetric cryptography have been proposed to prevent such attacks. Hence, this still calls for an efficient authentication scheme for VANETs.  A new technique of decentralized lightweight authentication scheme called as Trust-Extended Authentication Mechanism (TEAM) for Vehicle-to-Vehicle communication networks. TEAM adopts the concept of transitive trust relationships to improve the performance of the authentication procedure and only needs a few storage spaces. Moreover, TEAM satisfies the following security requirements: anonymity, location privacy, mutual authentication, forgery attack resistance, modification attack resistance, replay attack resistance, no clock synchronization problem, no verification table, fast error detection, perfect forward secrecy, man-in-the-middle attack resistance, and session key agreement.
