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...

Side-Channel Attack against CRYSTALS-Kyber

CRYSTALS-Kyber is one of the public-key algorithms currently recommended by NIST as part of its post-quantum cryptography standardization process. Researchers have just published a side-channel attack--using power consumption--against an implementation of the algorithm that was supposed to be...

KEMs and Post-Quantum age

Theyre here! NIST selected a first batch of post-quantum cryptographic key exchange and signature algorithms. The report is a nice read that explains a lot of the goals, candidates, selections, and rationales. I recommend Sections 2, 3.3, and 4.1. For key exchange, NIST selected only...

NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

The U.S. Department of Commerce's National Institute of Standards and Technology NIST has chosen the first set of quantum-resistant encryption algorithms that are designed to "withstand the assault of a future quantum computer." The post-quantum cryptography PQC technologies include the...

The NSA Says that There are No Known Flaws in NIST’s Quantum-Resistant Algorithms

Rob Joyce, the director of cybersecurity at the NSA, said so in an interview: The NSA already has classified quantum-resistant algorithms of its own that it developed over many years, said Joyce. But it didnt enter any of its own in the contest. The agencys mathematicians, however, worked with NI...
