KyberSlash attacks put quantum encryption projects at risk


A group of vulnerabilities known as KyberSlash potentially allow secret keys to be recovered from various implementations of the Kyber key encapsulation method for quantum-safe encryption.

The Kyber key encapsulation mechanism (KEM) for the quantum-safe algorithm (QSA) is officially implemented by CRYSTALS-Kyber, which is a member of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) algorithm family. It is a component of the National Institute of Standards and Technology’s (NIST) collection of algorithms created to resist attacks by quantum computing and is intended for universal encryption.
