Re: [Suit] SUIT Manifest MTI Algorithms

Hi,

The US NIST SP800-208 Recommendation for Stateful Hash-Based Signature
Schemes (October 2020)
specifies HSS/LMS and references the RFC specs developed by the IRTF Crypto
Forum for these hash
algorithms:

https://csrc.nist.gov/publications/detail/sp/800-208/final

Among followers of IRTF Crypto Forum, there is high visibility of these
hash algorithms.  There has also
been take-up in ISO, ITU-T, and other SDO specs, because these are
Post-Quantum Safe algorithms.

Cheers,
- Ira
