Survey for Secure IoT group communication

The Internet of Things (IoT) paradigm is progressing fast toward Internet adoption and reaching out to various industrial domains such as smart lighting. New IoT use cases leveraging multicast group communication increase the demand for security to protect a number of devices. Providing dedicated multicast security for constrained IoT environment is the key to make IoT service successful. In this paper, we survey the state of the art of secure IoT group communication among devices. We focus on the context of commercial smart lighting, as it has as several use cases that rely on secure group communication. The paper summarizes use cases and security requirements for the multicast group communication, state of the art approaches focusing on standardization activities. Furthermore, the paper shows the evaluation result of the new application layer security protocol, OSCORE. We concludes with a research outlook on open problems.
