Secure and Privacy-Preserving, Timed Vehicular Communications

The authors consider the problem of privacy (anonymity) and security in vehicular (V2V) communication, in particular securing routine safety messages. Traditional public key mechanisms are not appropriate for such applications because of the large number of safety messages that have to be transmitted by each vehicle, typically one message every 100???300ms. They first show that a recently proposed V2V communication scheme, the TSVC, based on the Time Efficient Stream Loss-tolerant Authentication (TESLA) scheme, is subject to an impersonation attack in which the adversary can distribute misleading safety information to vehicles, and propose a modification that secures it against such attacks.
