One of the aspects on which IBM the spotlight on the unveiling of the new z16 mainframes was compatibility with attack-resistant encryption by quantum computers. The company has now said it will be possible to take advantage of the four new NIST-standardized ciphers with an adapter update Crypto Express 8S.

Post-quantum encryption arrives on IBM z16 mainframes

IBM was directly involved in the creation of three of the four new encryption algorithms being standardized by NIST and it is not surprising, therefore, that it is ready to integrate them into its products.

Specifically, the z16 mainframes are already designed to take advantage of algorithms CRYSTALS-Kyberintended for key exchange using public key cryptography, e CRYSTALS-Dilithiumdeveloped for digital signatures.

The ciphers are already usable, but their current inclusion is more aimed not so much at their immediate use, but at giving companies the possibility of experiment and update their software for future compatibility. In fact, it will take a long time for all systems to be updated to the new algorithms, but this work must start now to be ready in the future. How writes Anne Dames, distinguished engineer in the division of cryptographic technologies at IBM, “[i mainframe] IBM z16 empowers you to start using cryptography quantum safe along with the classic one, as you start modernizing existing applications and building new ones. “

“Legal documents such as mortgages and loans that will need to be protected for 20 years or more, for example, need new algorithms quantum safe today”, continues Dames. And this is precisely the crux of the matter: you have to be prepared for the arrival of quantum computers, even if this happens in 20 years.
