A Lightweight Conditional Privacy-Preservation Protocol for Vehicular Traffic-Monitoring Systems

Vehicular traffic monitoring (VTM) is a promising cyber-physical system, but it faces many security and privacy challenges. Here, a new lightweight conditional privacy preservation (LCPP) protocol utilizes simple hash-chain techniques to secure VTM systems. The protocol not only supports the requirement of conditional privacy preservation, but also achieves efficient local revocation verification on the road.
