Privacy threat is one of crucial issues for the wide deployment of vehicular ad-hoc networks. Due to the open nature of the wireless communications, many kinds of attacks such as eavesdropping and traffic analysis can be launched by various malicious adversaries. Network coding allows intermediate nodes to encode/mix incoming message, thus it can provide a feasible way to thwart effectively eavesdropping and traffic analysis attacks. Inspired by newly developed secure network coding solution, the authors propose a privacy preservation scheme for online service access in VANET.
