Hi Deidre and the X-Wing Team,

I am happy to help with any effort to get X-Wing published as an RFC. X-Wing is already the de facto standard for practical use of ML-KEM in TLS, DTLS, and QUIC. I hope it will be MTI as soon as possible. I think it is essential to document X-Wing in an RFC. I think NIST should refer to X-Wing as a good example of a hybrid KEM in SP 800-227. Chosing a fast secure Montgomery curve and using SHA-3 as KDF are the optimal choices. I am against CFRG combining ML-KEM with anything else.

The only problem with X-Wing is that it is not generic, but X-Wing should be everybody's first hand choice if they want do deploy ML-KEM.

Cheers,
John

FYI the chairs have declined again to have an adoption call for X-Wing. The authors are now in discussion with the Independent Stream Editor to pursue review and publication there.

If you wish to volunteer document and cryptographic reviews for X-Wing we can take those to the ISE.

Thanks for all the interest and support!

Cheers,
Deirdre, on behalf of the X-Wing Team
