Quantum-Resistant Tunnels Now Available on iOS!
1. Open the app on your iOS device. 2. Navigate to Settings → VPN settings → Quantum-resistant tunnel. 3. Ensure the setting is switched to On.
Once the VPN connection is established, you’ll notice a “QUANTUM SECURE CONNECTION” status in green text on the main view of the app, confirming your connection.
The encryption used by WireGuard has no known vulnerabilities. However, the current establishment of a shared secret to use for the encryption is known to be crackable with a strong enough quantum computer. Although strong enough quantum computers have yet to be demonstrated, having post-quantum secure tunnels today protects against attackers that record encrypted traffic with the hope of decrypting it with a future quantum computer.
A WireGuard tunnel is established, and is used to share a secret in such a way that a quantum computer can’t figure out the secret even if it had access to the network traffic. We then disconnect and start a new WireGuard tunnel specifying the new shared secret with WireGuard’s pre-shared key option.
