Google has announced the first open-source quantum resilient FIDO2 security key implementation, which uses a unique ECC/Dilithium hybrid signature schema co-created with ETH Zurich.
FIDO2 is the second major version of the Fast IDentity Online authentication standard, and FIDO2 keys are used for passwordless authentication and as a multi-factor authentication element.
Google explains that a quantum-resistant FIDO2 security key implementation is a crucial step towards ensuring safety and security as the advent of quantum computing approaches and developments in the field follow an accelerating trajectory.
"As progress toward practical quantum computers is accelerating, preparing for their advent is becoming a more pressing issue as time passes," explains Google.
"In particular, standard public key cryptography, which was designed to protect against traditional computers, will not be able to withstand quantum attacks."
This new hybrid implementation is now part of the OpenSK, Google's open-source security keys implementation that supports the FIDO U2F and FIDO2 standards.
