摘要

A quantum safe vehicular communication system is essential for maintaining smooth traffic flow and preventing accidents in low visibility highway conditions. Although vehicular networks enable rapid information exchange, powerful adversaries threaten confidentiality and integrity through outsider attacks such as interception, intercept resend, man-in-the-middle, coherent, and Trojan horse attacks, and insider threats like forgery and collusion. To address this, we propose a Quantum Safe Vehicular Communication protocol using Quantum Secret Sharing and Controlled Alternate Quantum Walk-based hashing. Clustered vehicles and head nodes distribute quantum secured secret shares with a computation cost of \(\mathcal {O}(1)\) O ( 1 ) , ensuring efficient and reliable V2V and V2I communication.
