Post-Quantum Encryption Algorithm KyberSlash Patched After Side-Channel Attack Discovered
jd (Slashdot reader #1,658) shared this story from BleepingComputer. The article notes that "Multiple implementations of the Kyber key encapsulation mechanism for quantum-safe encryption, are vulnerable to a set of flaws collectively referred to as KyberSlash, which could allow the recovery of secr...
jd explains that Crystals-Kyber "was chosen to be the U.S. government's post-quantum cryptography system of choice last year, but a side-channel attack has been identified. From the article: CRYSTALS-Kyber is the official implementation of the Kyber key encapsulation mechanism (KEM) for quantum-safe algorithm (QSA) and part of the CRYSTALS(Cryptographic Suite for Algebraic Lattices) suite of algorithms. In a KyberSlash1 demo on a Raspberry Pi system, the researchers recovered Kyber's secret key from decryption timings in two out of three attempts...
