PQ-WireGuard: we did it again

June 8, 2021

Presenters

Mathilde Raynal - Kudelski Security/EPFL

Description

Virtual Private Networks (VPN) offer security and privacy properties for internet users such as authentication, confidentiality, or identity-hiding. In 2017, Jason Donenfeld introduced WireGuard, a fast and secure open-source VPN based on “modern” cryptography that aims to replace more complex solutions such as OpenVPN. With the arrival of quantum computers, the security of these VPN solutions is threatened. A fork of OpenVPN using post-quantum alternatives was proposed by Microsoft’s team, and concurrently, Hülsing and his team formally introduced quantum security in the WireGuard protocol. In the quantum adversarial scenario, the PQ-WireGuard software keeps its leading role in terms of computation and communication cost over PQ-OpenVPN.
