Google has introduced the primary quantum resilient FIDO2 safety key implementation as a part of its OpenSK safety keys initiative. The implementation makes use of a hybrid signature schema that mixes the safety of ECC towards normal assaults with Dilithium’s resilience towards quantum assaults. OpenSK is an open-source implementation for safety keys that helps each FIDO U2F and FIDO2 requirements. Google’s transfer to quantum-resistant encryption algorithms is a part of its broader efforts to change to cryptographic algorithms that may stand up to quantum assaults sooner or later.
The proposed FIDO2 safety key implementation is a mixture of ECDSA and the just lately standardized quantum resistant signature algorithm, Dilithium. Developed in partnership with ETH Zürich, the hybrid signature schema is a Rust-based memory-optimized implementation that solely requires 20 KB of reminiscence, making it appropriate for safety keys’ constrained {hardware}. Google hopes that this implementation, or a variant of it, can be standardized as a part of the FIDO2 key specification and supported by main internet browsers.
By incorporating quantum-resistant applied sciences early on, Google goals to guard customers’ credentials towards quantum assaults. The firm plans so as to add assist for quantum-resistant encryption algorithms in Chrome 116 to arrange symmetric keys in TLS connections. With the current standardization of public key quantum resilient cryptography, such because the Dilithium algorithm, Google sees a transparent path to safe safety keys towards quantum assaults. Google’s announcement is a vital step in enhancing password safety and encryption within the face of evolving cybersecurity threats.
