Abstract:
Internet of Things (IoT) devices are resource constrained. Therefore, many IoT applications rely on multicast in their transmission to preserve IoT node resources. However, security is a main concern in critical applications such as actuators control. Consequently, the multicast traffic has to be secured. Multicast security requires an efficient and scalable Group Key Management (GKM) protocol. In case of IoT, the situation is more difficult because of the dynamic nature of IoT scenarios. This paper introduces a new model for GKM based on using a context aware security server accompanied by a group of key distribution servers. The model efficiently distributes group encryption keys to IoT devices to secure the multicast sessions. The proposed solution is mathematically evaluated relative to the Logical Key Hierarchy (LKH) protocol. The comparison shows that the proposed model efficiently enhanced the performance for both the members and the key servers regarding load and key storage cost.
