Abstract: This paper presents Group-IKEv2, a group key management protocol supporting secure group communication based on multicast IPsec. Group-IKEv2 is an adaptation of the IKEv2 protocol for the IPsec suite, and is especially designed to address internet of things (IoT) scenarios composed of resource-constrained devices. Compared to static approaches, Group-IKEv2 enables dynamic and flexible establishment of IPsec group security associations as well as group key material. Also, it integrates the management and renewal of group key material, both on a periodical fashion and upon group membership changes. We have implemented Group-IKEv2 for the Contiki OS and tested it on the OpenMote resource-constrained platform. Our experimental performance evaluation confirms that Group-IKEv2 is affordable and deployable also on constrained IoT devices.
