Google announces new algorithm that makes FIDO encryption safe from quantum computers

New approach combines ECDSA with post-quantum algorithm called Dilithium.

The PQC algorithm used in the implementation of FIDO2 security keys takes a more cautious approach. It combines the elliptic curve digital signature algorithm—believed to be unbreakable by classical computing but easily broken with quantum computing—with a PQC algorithm known as Crystals-Dilithium. Crystals-Dilithium is now one of three PQC algorithms selected by NIST for use with digital signatures.

Cryptography

From Greek κρύπτω krýpto "hidden" and the verb γράφω gráfo "to write" or λέγειν legein "to speak". Cryptography is the practice of establishing a secure connection between two parties in the presence of a third party whom you don't want to be able to read your messages. Cryptographers design algorithms and protocols, which do exactly this (and many other things). They also use a lot of time looking for security holes in existing protocols to make sure they can still be trusted. This is called cryptanalysis.
