Vodafone and SandboxAQ Collaborate to Develop Quantum-Safe VPN for Enhanced Business Security

Vodafone has partnered with SandboxAQ, a spin-off from Alphabet, to address potential threats posed by quantum computers to future business smartphones and connections. In a press release, Vodafone highlighted the theoretical capability of quantum computers to break through current encryption methods, potentially allowing hackers to access sensitive data such as identity and payment information.

Vodafone believes that hackers are likely already stealing and storing encrypted data in anticipation of the “quantum revolution,” which would enable them to quickly decrypt and read the stolen information. Government-held data is reported to be among the targets of these hackers.

To ensure businesses are protected against these threats, Vodafone and SandboxAQ conducted a proof-of-concept test for a quantum-safe Virtual Private Network (VPN). VPN networks are widely used in corporate security to securely connect employees to company systems. The test involved adapting the VPN using cryptography algorithms from The National Institute of Standards and Technology (NIST), which has been working on developing cryptography algorithms suitable for quantum computers.

The test evaluated the impact of post-quantum cryptography on various activities such as web browsing, social media and chat applications, video and audio streaming, and mobile gaming using PQC-enabled mobile handsets. The selected post-quantum cryptography algorithms, chosen by NIST for standardization, were found to perform well with minimal impact on the quality of service in the telecommunications setting.

Based on the results, the researchers concluded that the use of hybrid classical/post-quantum algorithms for security processes involving cryptographic key exchange could be a promising approach. NIST is also considering a second group of post-quantum cryptography algorithms for digital signatures. Vodafone and SandboxAQ believe that combining traditional signature algorithms with hybrid key exchange can enhance security in business environments.
