A new "quantum proof" encryption standard is broken by a low-end PC

A new award-winning encryption standard is crackable by a PC with a single-core processor in under an hour. Naturally, the cryptographers who invented it were shocked!

Gizmodo:

Last month, The National Institute of Standards and Technology, or NIST, announced the winners of a years-long competition to develop new encryption standards, the likes of which have been designed to protect against a hypothetical (for now) threat that hasn't been invented yet: quantum computers. — Read the rest
