Dear ACE, With this update, we have aimed to make progress in the to-do presented in the interim. More specifically: - Clarified Client workflow and describe KDC discovery as close as possible to core pub-sub. - AIF-PUBSUB-GROUPCOMM Scope - added support for admin role for future-proofing; added delete role - Clarified Cose_key returned in Join Response and AEAD nonce construction based on a sender ID provided by the KDC (Partial IV is the message sequence number, Base IV provided by the KDC). - Checked off most Finalise Groupcomm Required and Optional List with the exception of the group rekeying further to be clarified.
