Recent advancements in the “Internet of Things” allowed “Things” or “nodes” to have virtual identities and exchange data and services. “Things” form distributed systems which lack central control and have flexible topologies. In this context, it is crucial to have a robust, scalable and adaptive trust model for trustworthy node communication between nodes (i.e., Things). In this paper, A Context-based Social Trust model for the Internet of Things (CBSTM-IoT) is presented. CBSTM-IoT integrates numerous factors such as direct and indirect trust; transaction context; owner trust; and social modelling of trust. Performance evaluation results validate that CBSTM-IoT benefits from using both direct observations and indirect recommendations to counter attacks and achieves satisfactory results in isolating malicious nodes in the network.
