On the Security of a Secure Batch Verification Scheme for VANET
Abstract:
Vehicular ad hoc networks is a special mobile ad hoc networks. Due to the limited bandwidth, high vehicle mobility and density of vehicles, scalability is a major challenge in VANETs. Recently, Sagarika Mohanty et al. proposed a secure RSU-Aided Aggregation and Batch-Verification Scheme for Vehicular Networks by using data aggregation technique. And they had shown that their scheme could provide conditional Privacy Preservation and Identity Traceability. Unfortunately, in this paper, we show that their scheme does not achieve these functions by analyzing the security of the scheme. Any one can distinguish whether the different messages is from the same vehicle. And the scheme is also not to resist replay attack. Finally, the corresponding attacks are given.
