Abstract:

   This document defines the security protocol Group Object Security for
   Constrained RESTful Environments (Group OSCORE), providing end-to-end
   security of messages exchanged with the Constrained Application
   Protocol (CoAP) 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 each other
   member of the group for pairwise OSCORE communication.  Group OSCORE
   can be used between endpoints communicating with CoAP or CoAP-
   mappable HTTP.
