That’s the value our own VPN is bringing to organisations like NATO, a diverse member organisation with a variety of post-quantum algorithms in use. We are entering a period where different countries are now recommending different encryption algorithms, so engineering our communications infrastructure to be interoperable and backward compatible is absolutely crucial. NIST’s new algorithms are only useful if we have agreed standards for their use and mature products that can accommodate them.”Īndersen Cheng, Executive Chairman, Post-Quantum added: “CJ and his collaborators have completed important work that makes it possible for tech companies to build quantum-safe VPNs that communicate to one another. The easiest way to prevent Harvest Now Decrypt Later attacks is to deploy a PQ VPN based on the new IETF standard. Much of the focus has been on NIST’s new post quantum encryption algorithms themselves, but this is insufficient unless you have a protocol that defines how the connectivity is done. Post-Quantum’s own Hybrid PQ VPN uses the new IETF standard and is already in use by NATO to secure its communications from quantum attack, supporting interoperable communications between NATO members.ĬJ Tjhai, CTO, Post-Quantum and original author of the new IETF standard said: “I’d like to thank all the technologists that collaborated with us on this IETF standard. The new IETF standard was proposed and designed by Post-Quantum, a British cyber security company that’s built a portfolio of market-ready quantum-safe cyber security products. This new IETF standard is the glue that allows parties using different public key encryption algorithms to talk with one another. This is a particularly important milestone for internet connectivity and security as we are transitioning from an era where the world relied upon just one or two algorithms (RSA and Elliptic Curve), to a situation where different nation states are deploying a wide variety of different post-quantum algorithms. Combining both old and new encryption is essential to ensure no disruption to the functioning of existing IT systems, and to protect data from attack by both classical and quantum computers. The novel approach prioritises interoperability by making it possible for multiple post-quantum and classical encryption algorithms to be incorporated into VPNs. The new IETF standard specifies how VPNs can exchange communications securely in the quantum age. Deploying a VPN based on new post quantum cryptography is the easiest way to protect data-in-transit from such attacks. The new US Quantum Computing Cybersecurity Preparedness Act states that the HNDL risk presents the highest threat to humankind and stipulates that quantum migration must start now. These attacks see hostile actors steal encrypted data now which can be decrypted once a sufficiently mature quantum computer comes online. ‘Harvest Now Decrypt Later’ (HNDL) attacks currently represent the greatest quantum cybersecurity threat. The new protocol has already been used by Banque de France and Deutsche Bundesbank to secure payments messages, paving the way for full adoption by the Bank for International Settlements to secure communications between the world’s central banks. LONDON-( BUSINESS WIRE)-The world’s efforts to secure digital communications from the threat posed by quantum computers took a significant leap forward today as a new standard for quantum-safe Virtual Private Networks (VPN) was ratified by the Internet Engineering Task Force (IETF).
