The wolfSSL team would like to announce support for XMSS (eXtended Merkle Signature Scheme) and XMSS^MT (Multi-Tree XMSS) post-quantum cryptographic signature schemes to wolfCLU. The implementation includes key generation, signing, and verification capabilities.
Note that this feature includes best-effort state management for stateful private keys. We have done our best to implement state management, but without knowing the implementation of the file system, we cannot guarantee secure storage of the state.
This addition provides wolfCLU users with access to quantum-resistant signature schemes, particularly important for long-term security requirements. The implementation follows the stateful signature paradigm required by XMSS/XMSS^MT while maintaining usability through the familiar wolfCLU interface.
If you have questions about any of the above, please contact us at facts@wolfSSL.com or call us at +1 425 245 8247.
