Abstract:
   This document defines the security protocol 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 protocol
   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.
   Group OSCORE can be used between endpoints communicating with CoAP or
   CoAP-mappable HTTP.
