Many applications for ad hoc networks are based on a point-to-multipoint (multicast) communication paradigm, where a single source sends common data to many receivers, or, inversely, on a multipoint-to-point communication paradigm, where multiple sources send data to a single receiver. In such scenarios, communication can be secured by adopting a common secret key, denoted as ''Group key'', shared by multiple communication endpoints. In this paper, the authors propose a novel centralized approach to efficiently distribute and manage a group key in generic ad hoc networks and Internet of Things (IoT), while reducing the computational overhead and network traffic due to group membership changes caused by users' joins and leaves.
