Fascinating article, will crypto ever be hack free?

One of the four encryption algorithms America's National Institute of Standards and Technology (NIST) recommended as likely to resist decryption by quantum computers has had holes kicked in it by researchers using a single core of a regular 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 a $50,000 bounty for anyone who could crack it.

Belgian boffins Wouter Castryck and Thomas Decru claim to have done just that, using some good ol' non-quantum x86 silicon.
