   This document describes a mode for protecting group communication
   over the Constrained Application Protocol (CoAP).  The proposed mode
   relies on Object Security for Constrained RESTful Environments
   (OSCORE) and the CBOR Object Signing and Encryption (COSE) format.
   In particular, it is defined how OSCORE should be used in a group
   communication setting, while fulfilling the same security
   requirements for request messages and related response messages.
   Source authentication of all messages exchanged within the group is
   ensured, by means of digital signatures produced through private keys
   of sender endpoints and embedded in the protected CoAP messages.
