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 Royal Institute of Technology said in a paper.
CRYSTALS-Kyber is one of four post-quantum algorithms selected by the U.S. National Institute of Standards and Technology (NIST) after a rigorous multi-year effort to identify the next-generation encryption standards that can withstand huge leaps in computing power.
