ExpressVPN, the leading VPN service provider, has announced an upgrade to their encryption protocols in response to the increasing threat of quantum computing. The new post-quantum protections will be available across all platforms, including Android, iOS, Linux, Mac, and Windows.

With the rise of quantum computers, traditional end-to-end encryption is at risk of being compromised. Quantum computers can process complex calculations much faster than classical computers, potentially allowing them to break into encrypted data. While widespread quantum computing is still a decade away, “harvest now, decrypt later” attacks are already a concern.

ExpressVPN aims to stay ahead of the curve and protect user data before quantum computing becomes an immediate threat. Pete Membrey, the Chief Engineering Officer at ExpressVPN, emphasized the importance of being proactive in the VPN industry’s transition to a quantum-safe future.

The provider’s approach to post-quantum protection involves integrating advanced encryption methods into their existing protocols. The team incorporated the open-source WolfSSL cryptography library, known for its speed, into their ExpressVPN Lightway protocol. The transition to the new encryption was accompanied by extensive testing and collaboration with WolfSSL to ensure security and reliability.

ExpressVPN’s post-quantum protections utilize algorithms from the National Institute of Standards and Technology (NIST), specifically the Kyber algorithm. The Kyber algorithm was chosen as a candidate for general post-quantum encryption. The protocol also takes a hybrid approach, combining both new and old encryption keys to provide comprehensive security.

ExpressVPN is not the only company focusing on post-quantum encryption. Other security software providers, including Tutanota, Proton, Signal, and PureVPN, have also taken steps towards implementing quantum-safe encryption.

Despite the competition, Membrey believes that ExpressVPN has an advantage due to the flexibility of their Lightway protocol. While other VPN protocols require significant changes to support post-quantum encryption, Lightway allows for seamless integration of new security features.

As the race for post-quantum encryption continues, ExpressVPN remains committed to staying at the forefront of technological advancements. By collaborating with the open-source community and continuously evolving their solutions, ExpressVPN aims to ensure the security and privacy of their users in an increasingly quantum-focused world.
