Formal Trust Architecture For Assuring Trusted Interactions In the Internet of Things The Internet of Things (IoT) has provided a flexible platform for a large number of heterogeneous devices to dynamically join and leave the network. This enhances the availability of a diverse range of services provided by a network. However, this dynamic expansion of the network with mobile IoT devices introduces a major challenge to security especially related to management of trust across the diverse IoT platforms. Thus arises the necessity for a mechanism that can ensure the selection of secure and trusted devices as these devices try to join the network. In this work, an effective formal approach to trust modeling mechanism has been investigated to support dynamic trust development between devices based on two-tier trust architecture.
