Experts Discover Flaw in U.S. Govt’s Chosen Quantum-Resistant Encryption Algorithm

A group of researchers has revealed what it says is a vulnerability in a specific implementation of CRYSTALS-Kyber, one of the encryption algorithms chosen by the U.S. government as quantum-resistant last year.
The exploit relates to « side-channel attacks on up to the fifth-order masked implementations of CRYSTALS-Kyber in ARM Cortex-M4 CPU, » Elena Dubrova, Kalle Ngo, and Joel Gärtner of KTH
