L-VAKMC: Lightweight Authentication and Dynamic Key Agreement for VANET Multi-Entity Communications
- Published
- Record updated
Summary
This paper proposes a lightweight, scalable authentication protocol for VANET communications spanning six modes, including Vehicle-to-EdgeRSU, Vehicle-to-Vehicle and User-to-Distributed Server. It combines elliptic-curve cryptography, hash-based commitments and ephemeral key exchange to provide mutual authentication and end-to-end confidentiality. The authors report formal and informal security assessments and performance benchmarking, claiming strong resistance to prevalent threats and efficiency for real-time vehicular deployment.
