Virtual Private Network (VPN) with Post-Quantum Cryptography (PQC)

This paper introduces qTrustNet VPN, a next-generation Virtual Private Network (VPN) designed to enhance security in the quantum era. With the rapid advancement of quantum computing, traditional encryption methods face obsolescence, necessitating more robust security solutions. qTrustNet VPN addresses this need by integrating the WireGuard protocol, known for its simplicity and high performance, with Post-Quantum Cryptography (PQC) algorithms developed by the National Institute of Standards and Technology (NIST). These PQC algorithms are designed to withstand the decryption capabilities of quantum computers, providing long-term security.
