   This document defines Group Object Security for Constrained RESTful
   Environments (Group OSCORE), providing end-to-end security of CoAP
   messages exchanged between members of a group, e.g., sent over IP
   multicast.  In particular, the described approach defines how OSCORE
   is used in a group communication setting to provide source
   authentication for CoAP group requests, sent by a client to multiple
   servers, and for protection of the corresponding CoAP responses.
   Group OSCORE also defines a pairwise mode where each member of the
   group can efficiently derive a symmetric pairwise key with any other
   member of the group for pairwise OSCORE communication.
