An identity‐based secure VANET communication system

Abstract Vehicular ad‐hoc networks (VANETs) are mobile networks intended to connect vehicles and provide secure communication. In this direction, many researchers worked on establishing secure communication in VANETs. However, VANETs still face potential security and privacy issues due to network openness. In this paper, we proposed a secure communication system for VANETs with privacy, consisting of an Enhanced privacy‐preserving mutual authentication procedure for safe communication in V2V and deriving a session key using vehicle identities and time stamps the secret values (nonce) shared during the session. Further, we compared the proposed technique with existing techniques, and satisfactory results were obtained in favor of the proposed less computation. Finally, a formal security model is established to secure against unknown key share attacks, replay attacks, and key‐compromised impersonation attacks.
