   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 defines how OSCORE is used in a group communication
   setting, while fulfilling the same security requirements for group
   requests and responses.  Source authentication of all messages
   exchanged within the group is provided by means of digital signatures
   produced by the sender and embedded in the protected CoAP messages.
