Is PQC Broken Already? Implications of the Successful Break of a NIST Finalist

Written by Jim Gable, Shannon Gray, and Denis Mandich of the CSA Quantum-Safe Security Working Group. Reviewed by Mehak Kalsi and Bruno Huttner. The cybersecurity industry was shocked recently by a paper from a Swedish team that broke one of the four NIST algorithms for Post-Quantum Cryptography (PQC). Three researchers in Stockholm published a paper that described a side-channel attack coupled with recursive machine learning (ML) code to break CRYSTALS-Kyber, the key exchange algorithm appro...
