Verizon Says Its New VPN Can Resist Quantum Computer Attacks
Verizon is testing a new "quantum secure" VPN, which it hopes will be strong enough to withstand attack from quantum computers, which could neutralize current cryptography with their immense computing prowess. As quantum computers move ever closer to reality, researchers around the world are designing post-quantum algorithms and hardware that they hope will be able to support the seemingly limitless computing performance that the new technology promises. Verizon has now jumped on the bandwagon by testing a tool that it hopes will one day challenge the potential of the quantum computer to break today's public key encryption ciphers.

“This technology uses session key exchange or cryptographic cipher security mechanisms that can provide a higher level of protection. Essentially, it is a solution that improves current encryption methodologies to make them even more difficult to hack tomorrow,” says Verizon.

Post-quantum computing

Verizon's Quantum Secure VPN is based on encryption keys generated using post-quantum cryptographic methods. In the test, Verizon used its quantum-secure VPN between one of its labs in London and a US-based hub in Ashburn, Virginia. While VPNs have always been popular for their privacy-enhancing features, lately they have become a staple of the computing stack of the increasingly remote workforce that depends on them to securely access resources. remote corporate. As Verizon explains, the VPN relies on cryptography protocols that, while very secure, can be cracked with incredible amounts of computation. While the process is currently unfeasible, it won't be much of a challenge for a quantum computer. "Many secure communications are based on algorithms that have been very successful in providing strong cryptographic keys for decades. But there is enough research to indicate that these can be broken when a quantum computer is available at a certain capacity," Venkata Josyula, CTO at Verizon he told ZDNet. Josyula adds that the company is hopeful that its quantum-secure VPN can eventually guarantee connection integrity, even in the post-quantum era. via ZDNet
