The proposed method delegates the authentication and authorization of new client nodes that join an OSCORE group through a Group Manager server. This approach builds on the ACE framework for Authentication and Authorization, and leverages protocol-specific transport profiles of ACE to achieve communication security, proof-of-possession and server authentication.}, }
