Interval evaluation of trust and reputation for Internet of Things

Dynamic trust management is a significant part of functioning mobile wireless networks of Internet of Things (IoT). That is reliable data fusion and mining, qualified services with context-awareness, and enhanced user privacy and information security. Trust management in IoT networks is important due to dynamically changing network environments and the lack of centralized authority. A mobile network is vulnerable to many attacks. The objective of this article is to present definition of trust and reputation determining in a coalition of the IoT objects. This paper is aimed to propose a trust determining method to the object of interaction in a fully decentralized IoT system, taking into account the reputation of this object, in conditions the uncertainty of information about object and nodes that are trusted to it.
