Crypto-Agility in the LMS Private Key

Here at wolfSSL, we have enhanced our Leighton-Micali Signature (LMS) implementation with a new optional state serialization feature that significantly improves key reload performance for applications requiring frequent signing operations. The LMS post-quantum signature scheme is stateful by nature, meaning each signature operation updates the internal state of the private key, and this state must […]
