Dynamic Key Distribution for Secure Group Communications in Constrained Environments

Group communication -- especially in form of multicast -- is a famous communication pattern in constrained networks, e.g.~in the Internet of Things~(IoT), Wireless Sensor Networks (WSN) or Device to Device (D2D) communication. However, it comes with mandatory management overhead during the life-cycle of a group, which is usually favored due to the potential energy savings ones the connection is set up. The management paradigm worsens, if the connection within and the management of the group has to be secure and in turn requires security management. Security and cryptography, however, need special attention when used in constrained environments. The proposed thesis will connect group management, group communication and security management and apply them to constrained environments.
