Decentralized secure framework for social collaborative Internet of Things

The Social-Collaborative Internet of Things (SCIoT) provides the ability for objects to autonomously establish social relationship among them based on the rules imposed by its owners'. This paper proposes a new secure framework for SCIoTto tackle the issues related to security and privacy. The proposed framework adopts a decentralized architecture to handle the problems of large-scale deployment and management of heterogeneous objects in different Internet of Things platforms. The proposed framework consists Relationship Based Dynamic Trust Management Protocol to ensure trustworthiness among objects in the dynamic environment of SCIoT.
