Abstract

With the development of vehicle communication technologies, vehicular ad hoc networks (VANETs) achieve communication through short distance communication technology. However, the privacy of vehicles and messages are vulnerable attacked by adversary due to the dynamic network topology. To enhance the security of VANETs, a privacy protection mechanism is designed based on secrete sharing. The mechanism allows vehicles to use pseudonym to protect its privacy, and the exchange entropy is as a measure to evaluate the exchange conditions of the pseudonym to avoid the continuous tracking by the attackers; the message security can be protected by secret sharing. The security and performance analysis are carried out to demonstrate that our scheme can reduce the risk of message leakage and better protect the VANETs’ privacy.
