Privacy-Preserving Vehicular Communication Authentication with H...

Existing secure and privacy-preserving schemes for vehicular communications in vehicular ad hoc networks face some challenges, e.g., reducing the dependence on ideal tamper-proof devices, building efficient member revocation mechanisms and avoiding computation and communication bottlenecks. To cope with those challenges, we propose a highly efficient secure and privacy preserving scheme based on identity-based aggregate signatures. Our scheme enables hierarchical aggregation and batch verificati
