Post-quantum crypto cracked in an hour with one core of an ancient Xeon
Post-quantum crypto cracked in an hour with one core of an ancient Xeon Laura Dobberstein – August 3, 2022 20h ago NIST's nifty new algorithm looks like it's in trouble One of the four encryption algorithms the US National Institute of Standards and Technology (NIST) recommended as likely to resist decryption by quantum computers has has holes kicked in it by researchers using a single core of an Intel Xeon CPU, released in 2013.… The Supersingular Isogeny Key Encapsulation (SIKE) algorithm was chosen by NIST just last month as a candidate for standardization, meaning it advanced to an extra round of testing en route to adoption. Within SIKE lies a public key encryption algorithm and a key encapsulated mechanism, each instantiated with four parameter sets: SIKEp434, SIKEp503, SIKEp610 and SIKEp751. Microsoft – whose research team played a role in the algorithm's development along with multiple universities, Amazon, Infosec Global and Texas Instruments – set up
