All the Things PQ – End-to-End PQ-Secure FIDO2 Protocol (Q21c)
Due to its widespread usage, the FIDO2 protocol urgently needs to be migrated to be post-quantum secure. This presentation will explain the steps taken over the last two years towards achieving a PQ secure FIDO2 protocol. It will delve into the analysis of the protocol’s quantum readiness, the replacement of quantum-vulnerable asymmetric cryptography algorithms, and the presentation of the first end-to-end post-quantum secure implementation of the FIDO2 protocol, recently open-sourced. Attendees will gain insights into potential roadblocks and solutions for implementing post-quantum cryptography in FIDO2 authentication.
