I have now uploaded a (very rough) first draft describing how to extend the SIV mode of operation to non-AES ciphers and MACs, as previously discussed on this list.

The I-D is available here: https://datatracker.ietf.org/doc/draft-madden-generalised-siv/
The source is on Github here: https://github.com/NeilMadden/draft-madden-generalised-siv

Feedback welcome. Hopefully I’ve managed to wrestle xml2rfc to produce the right output.

Kind regards,

Neil Madden
