“As quantum computing advances, the traditional encryption methods used by most current VPN protocols will eventually become vulnerable. By integrating PQE into our infrastructure, we are taking a key step to ensure the confidentiality and resilience of our users’ data, both now and in a post-quantum future ,” says Marijus Briedis, CTO of NordVPN.
In September 2024, NordVPN released an update for its Linux application that included the first enhancement to the NordLynx protocol with post-quantum encryption. NordLynx is a high-performance protocol, based on WireGuard, known for its speed and security. This updated version met the latest standards from the National Institute of Standards and Technology (NIST) for post-quantum encryption. In addition to protecting Linux users from quantum decryption, it allowed for the collection of key performance data, such as the impact on connection speed and latency.
“This data was crucial in taking the next step and incorporating quantum-resistant encryption across our other platforms,” Briedis adds. “Our experience with Linux showed that we could maintain the highest level of connection quality and speed. That’s why we decided to extend this protection to our other applications and strengthen data security for the long term.”.
Post-quantum encryption can be enabled in the app settings, under "Connections". When the switch is turned on, the feature is automatically activated every time a connection is established using the NordLynx protocol
