A framework to manage Trust in Internet of Things

The proliferation of new technologies and enhanced communication protocols rising expectations of internet users towards ubiquitous connectivity. Internet of Things (IoT) is an evolving technology that facilitates ubiquitous communication between uniquely identifiable heterogeneous physical objects seamlessly through the internet. Although, lots of efforts have been made to adopt IoT globally, its deployment suffers various research challenges. A critical issue that adversely affects the performance of IoT is Security. Inherent characteristics of IoT environment like limited resources, wireless channel, heterogeneous communication protocols, battery operated devices etc. restrict the use of traditional security solutions for IoT environment. Trust Management is an important aspect of security which ensures the reliability of the system by analyzing the behaviour of devices over the time to capture their malicious activities. This paper is intended to introduce about the importance of Trust Management over Security and Privacy in uncertain environments like IoT. In this paper, we present a generic framework to manage Trust considering all the qualitative and quantitative parameters. The paper also highlights the major requirement that needs to be considered while embedding Trust Management with IoT.
