+Candidate group members acting as ACE Clients and authorized to join a group can interact with the Key Distribution Center (KDC) acting as ACE Resource Server and responsible for that group, in order to obtain the necessary keying material and parameters to communicate with other group members.
 
 In particular, this document defines the operations and interface available at the KDC, as well as general message formats for the interactions between Clients and KDC. At the same time, communications in the group can rely on different approaches, e.g., based on multicast {{I-D.ietf-core-groupcomm-bis}} or on publish-subscribe messaging {{I-D.ietf-core-coap-pubsub}}, and can be protected in different ways.
