Efficient Cross-Layer Handover Authentication for Secure Communication in VANETs

This paper addresses the critical need for secure and resilient handover authentication processes in modern vehicular communication systems, characterised by low latency and high reliability. Introducing a cross-layer handover technique, our approach utilises a physical layer handover method leveraging the substantial decorrelation of channel responses between diverse network terminals. Emphasising the lightweight nature of the solution, our method ensures efficient authentication during vehicular handovers. The proposed methodology, validated through experimental analysis, offers a promising solution to the increasing challenges posed by wireless communication vulnerabilities in the context of modern vehicles.
