Google introduces FIDO2 security key

by nativetechdoctor

Google has implemented a FIDO2 security key capable of implementing quantum-resistant cryptography as part of the OpenSK security key initiative.

According to The Hacker News, this implementation of an optimized solution for open-source hardware is used by Google using the new ECC/Dilithium hybrid signature scheme, which benefits from ECC’s security against standard attacks and Dilithium’s resilience to quantum attacks

The concept of quantum attack was developed from quantum computers, which increase the processing speed many times over conventional computers. As a result, tasks like password cracking, which were once thought to take a few hundred to several thousand years, are now much shorter with quantum computers. Therefore, quantum attacks are being considered as an upcoming trend, perhaps even more dangerous than AI (artificial intelligence). In particular, standard public-key cryptography, which is designed to protect against traditional computers, will not be able to resist quantum attacks.

OpenSK is an open-source implementation of security keys written in Rust, supporting both the FIDO U2F and FIDO2 standards. The development comes less than a week after Google said it plans to add support for quantum-resistant encryption algorithms in Chrome 116 to establish symmetric keys in TLS connections. It is also part of a move to cryptographic algorithms that can resist future quantum attacks, which requires early incorporation of such technologies to facilitate gradual deployment
