Hi Hannes,

Thanks for your reply.

I am also pursuing it in the TLS WG.

Regards,
Jay

Hi Jay,

judging from the content of the document I unfortunately need to tell you that the DICE working group is the wrong place to discuss such a document.

The DICE WG is focused on using DTLS as is (without making extensions and modifications). The TLS group is the right place to discuss your draft.

Ciao
Hannes
