Abstract
Recently, security and privacy have been one of the main concerns that impedes the development of vehicular ad hoc networks (VANETs). In this paper, we put forward an access control with authentication scheme for disseminated messages in VANETs. In the scheme, we integrate pseudonym with identity based signature (IBS) which could not only authenticate the messages in vehicular communication, but also protect the privacy of message generators. When vehicles receive numerous messages that need to be authenticated in a short time, we also apply batch verification to improve the efficiency of message disseminating. Then we adopt ciphertext policy attribute based encryption (CP-ABE), which provides access control service to set expressive and flexible access structure for the specified vehicles in VANETs communication. The experimental results show that the proposed scheme is efficient in message authentication and access control for vehicular communication in VANETs.
