Guidance on Post-Quantum Cryptography in FIDO2

[devi1207]

I’m currently exploring the integration of post-quantum cryptography into the FIDO2 framework . I was hoping to get some guidance or references to sources that would help in understanding the challenges and solutions related to implementing post-quantum cryptographic algorithms with FIDO2.

Any insights or resources you can share would be greatly appreciated.

The main challenges are in the cryptography module. Pico Keys use MbedTLS, so PQ should be supported by MbedTLS.
After this, we should revisit the specs and adjust them to support PQ keypairs and operations with them.
