Group signatures for secure and privacy preserving vehicular ad hoc networks

The security of Vehicular Ad Hoc Networks (VANETs) plays a key role in protecting against bogus and malicious messages, misusing at roads, eavesdropping etc. Nowadays, common cryptographic solutions guarantee message integrity, authentication, non-repudiation and privacy which is required as a serious requirement in VANETs due to the possibility of tracking of drivers by malicious observers. The related and prior works ensure security and privacy. Nevertheless, the efficiency of these schemes is usually low or there is the possibility of denial of services attacks. The main goal of our paper is to provide initial design of a scheme which ensures privacy, security and efficiency. The proposed scheme can also protect against several Denial of Services Attacks. We compare our proposed solution with related solutions and outline the evaluation of our scheme.
