LMS and XMSS are stateful hash-based signature schemes (NIST SP 800-208) suited to long-lived firmware and code signing. wolfSSL has added support for both post-quantum cryptographic (PQC) algorithms to wolfHSM. This feature leverages the hardware security module (HSM) to securely and persistently store the “stateful” key and counter for both algorithms, as well as perform signing and verification operations used in secure boot, firmware verification, and data archival.
