An Improved and Privacy-Preserving Mutual Authentication Scheme with Forward Secrecy in VANETs

Vehicular ad hoc network (VANETs) plays a major part in intelligent transportation to enhance traffic efficiency and safety. Security privacy are the essential matters needed be tackled due open communication channel. Most of existing schemes only provide message authentication without identity authentication, especially inability support forward secrecy which is security goal schemes. In this article, we propose privacy-preserving mutual scheme with batch verification for VANETs both authentication. More importantly, proposed achieves secrecy, means exposure shared key will not compromise previous interaction. The proof shows that our can withstand various known attacks, such as impersonation attack forgery attack. experiment analysis results based on computation cost demonstrate more efficient compared related
