IBM researchers have announced development of new "quantum safe" encryption techniques that they plan to deploy to the IBM Public Cloud in 2020. The techniques have also been prototyped as part of a quantum safe enterprise class tape system.
According to the announcement, the new encryption algorithms are based on algebraic lattices, a class of mathematical problems that have not yet been shown to be susceptible to quantum computing solutions. The algorithms are implemented in "Cryptographic Suite for Algebraic Lattices" (CRYSTALS), a collection based on two primitives: Kyber, a secure key encapsulation mechanism, and Dilithium, a secure digital signature algorithm.
IBM has donated the quantum safe algorithms to OpenQuantumSafe.org for developing additional open standards and has submitted them to NIST for standardization.
