Utilization of Quantum Random Numbers in Crystal-Kyber based Post Quantum Virtual Private Network for Vehicular Communication

Virtual Private Networks (VPN) have greatly contributed towards enhancing the data security of users over the Internet. Even extension of office environment and remote access is possible due to VPNs. However, the current VPN technologies pose a threat from Quantum-Powered Adversaries as these systems can break the Public Key Encryption Schemes used by VPN to share session keys. Moreover, these systems are also capable to guess random numbers generated using Pseudo-random generators. In this paper, we propose a True Random Number based Crystal Kyber Post Quantum Virtual Private Network (PQVPN) and analyse its strength with respect to classical and quantum adversaries. We also present our comparison against other PQVPN solutions and discuss its viability in Vehicular Network.
