    abstract =  {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. using IP multicast. In particular, the described approach defines how OSCORE should be used in a group communication setting to provide source authentication for CoAP group requests, sent by a client to multiple servers, and the corresponding CoAP responses.},
