Dear MbedTLS,

Can you please help to provide some references for LMS stateful signatures schemes support in MbedTLS,

May be something like documentation and github repo link?

Unfortunately I am not able to find it online?

Thanks,
Raunak

Hi Raunak,

Mbed TLS today supports LMS stateful hash-based signature scheme. While supporting other PQC algorithms is in the Mbed TLS project roadmap, the team isn’t actively working on it. The focus for the team now is preparing for Mbed TLS 4.0.

Feel free to ask any further technical questions in the Mbed TLS public mailing list - mbed-tls@lists.trustedfirmware.org (https://lists.trustedfirmware.org/mailman3/lists/mbed-tls.lists.trustedfirmware.org/)

Regards,

Shebu

Dear Trusted Firmware Team,

I hope this message finds you well. My name is Raunak, and I am a Security Engineer at Micron Technology.

I would like to inquire whether the embedTLS library has been updated to include Post-Quantum Cryptography (PQC) algorithms such as LMS, HSS, and XMSS.

Additionally, is the embedTLS team actively working on integrating these PQC algorithms?

Thank you for your assistance.

Best regards,
Raunak
