Secure and Efficient Protocol for Vehicular Ad Hoc Network with Privacy Preservation

Security is a fundamental issue for promising applications in a VANET. Designing a secure protocol for a VANET that accommodates efficiency, privacy, and traceability is difficult because of the contradictions between these qualities. In this paper, we present a secure yet efficient protocol for a VANET that satisfies these security requirements. Although much research has attempted to address similar issues, we contend that our proposed protocol outperforms other proposals that have been advanced. This claim is based on observations that show that the proposed protocol has such strengths as light computational load, efficient storage management, and dependability.
