Secure Protocol for VANETs Communication

Vehicular ad hoc Networks (VANETs) are receiving great attention lately from academia and industries as well. So various research is going on covering different aspects of VANETs including security and safety of communication channels. One of the major challenges is preserving the privacy and security of vehicles while communicating with each other. Security becomes challenging when we have to trace the malicious nodes, in the network to punish or revoke malicious nodes, as we have to hide identity of sender during communication. In this article, we propose a secure authentication protocol for communication in VANETs that can achieve desired conditional privacy along with security during transmission of messages.
