Google Introduces First Quantum Resilient FIDO2 Security Key Implementation


As part of its OpenSK security keys project, Google on Tuesday revealed the first quantum robust FIDO2 security key implementation. Elie Bursztein and Fabian Kaczmarczyck stated that “this open-source hardware optimized implementation uses a novel ECC/Dilithium hybrid signature schema that benefits from the security of ECC against standard attacks and Dilithium’s resilience against quantum attacks.”

Rust-based OpenSK is an open-source security key implementation that complies with both FIDO U2F and FIDO2 specifications.x000D The news comes less than a week after the tech giant announced intentions to include support for symmetric key establishment in TLS connections using quantum-resistant encryption methods in Chrome 116.
