Abstract
In today’s interconnected world, Virtual Private Networks (VPNs) are essential for
secure communication and data protection. However, with the rise of quantum
computing, the security landscape is rapidly changing, necessitating advanced measures
to secure VPN infrastructures. By integrating post-quantum hybrid cryptography into
VPNs, organizations can fortify their security measures and safeguard sensitive
information against the threats posed by quantum computing. For that we propose a
hybrid cryptography approach to integrate post-quantum security into Virtual Private
Network protocols. Our approach utilizes the Kyber key encapsulation mechanism
(KEM) in combination with the WireGuard VPN protocol to encrypt the public key
before exchanging it with the server. We conducted a security analysis of our proposed
approach and compared it to classical VPN protocols like OpenVPN and WireGuard
without post-quantum security. Our findings demonstrate that the proposed hybrid
approach provides a higher level of security against attacks by quantum computers. the
performance evaluation of our approach demonstrates that it performs comparably to
the original WireGuard protocol in terms of computational overhead and latency while
outperforming OpenVPN in terms of key generation and encryption speed
