Abstract
We present a secure, privacy-preserving car parking assistance application using priority-based vehicular communications. The proposed technique utilizes two modified Elliptic Curve algorithms for vehicular message authentication between parking vehicles and corresponding infrastructure. We address the major challenges associated with VANET security and user privacy. The standard Wireless Access in Vehicular Environment (WAVE) protocol suite has been used to construct our signature mechanism, application data secrecy, and message integrity. Security analysis proves the resilience of the scheme against all known attacks. We also investigate network performances in order to justify the effectiveness of the scheme for practical use.
