Virtual Private Networks (VPN)

Verizon Tests Quantum Safe Virtual Private Network (VPN)

Verizon is testing how a Quantum Safe Virtual Private Network (VPN) can enhance protection of data today in order to thwart hackers in the future. As quantum computers become more advanced, they will have the potential to break today’s public key encryption ciphers. Theoretically, hackers could capture data riding on networks today and store it until quantum computers have the power to break the encryption. It’s a little like stealing a bank safe today and holding on to it until someone discovers how to pick the lock. Verizon, and others, believe the key to safeguarding information will be a Quantum Safe VPN. This technology uses session key exchange security mechanisms or cryptographic ciphers that can provide a higher level of protection. Essentially, it’s a solution that enhances encryption methodologies today in order to make them even more difficult to hack tomorrow.

Microsoft, OpenVPN, Post-Quantum Computing

Recently, Microsoft made virtual private networks (VPNs) and post-quantum cryptography (PQC) cryptosystem experimentation available for public study. Making use of the widely acclaimed OpenVPN software, MS combined OpenVPN with a PQC kit. The present iteration only protects data tunneling between the client and the VPN server with purportedly PQC-safe encryption algorithms. As data exits this trusted network onto the internet (public), classical cryptography takes over the encryption, increasing risk to the data’s confidentiality. The MS project complements the Open Quantum Safe project and NIST’s Post-Quantum Cryptography endeavors. Read on for further detail.
