ABSTRACT
The support of seamless collaboration between users as well as between their devices can be seen as one of the key challenges for this vision to come true. IdM requires an integrated and often complex infrastructure where all involved entities must be trusted for specific purposes depending on their role. In the vision of ubiquitous computing, the activities of daily life are supported by a multitude of heterogeneous, loosely coupled computing devices. The support of seamless collaboration between users as well as between their devices can be seen as one of the key challenges for this vision to come true. Designing a trust management model to provide trust in IoT is thus an important step towards achieving the privacy and security of entities in such a decentralized, distributed and mobile space. In this context, without human judgment, the challenge for devices is to be able to distinguish other peers' identities and behaviours autonomously.
