Quantum privacy‐preserving service for secure lane change in vehicular networks

Secure Multiparty Computation (SMC) enables multiple parties to cooperate securely without compromising their privacy. SMC has the potential offer solutions for privacy obstacles in vehicular networks. However, classical implementations suffer from efficiency and security challenges. To address this problem, two quantum communication technologies, Quantum Key Distribution (QKD) Oblivious were utilised. These technologies supply symmetric oblivious keys respectively, allowing fast secure inter-vehicular communications. are integrated with Faster Malicious Arithmetic Transfer (MASCOT) protocol form a (QSMC) platform. A lane change service is implemented which vehicles broadcast private information about intention exit highway. The proposed QSMC approach provides unconditional even against computer attacks. Moreover, cost of use case decreased by 97% when compared implementation. computation increased 42%. For open space scenarios, reduction especially important, because it conserves bandwidth free-space radio channel, outweighing increase cost.
