Friendliness Based Trustworthy Relationship Management (F-TRM) in Social Internet of Things

Abstract

Integrating social networking features into the Internet of Things (IoT) has evolved to a new era of Social Internet of Things (SIoT). SIoT enables the social interaction among various devices, facilitating the data sharing for achieving similar applications. SIoT devices are capable of making any number of friends. But this friendliness property thrusts for providing reliable and secured services. Therefore, the prime necessity of a trust management scheme in SIoT paradigm is to ensure safer communication among the social devices. In this work, an energy efficient and light weight Friendliness based Trustworthy Relationship Management model for providing reliable services in SIoT is proposed. We also present a cryptographic key establishment strategy based on the device friendship directory updation. A Dynamic Friendship Supervision scheme is proposed for managing the device friendliness. Based on the updated friendship directory, a Privacy Protection Paradigm is modelled and implemented using a set of cryptographic techniques. Robustness of the proposed relationship approach which delivers trust, privacy and security is validated using two distinct real-world datasets such as MIT AI and ARAS dataset containing 201 sensors. Experimental outcomes attest that the proposed trust management model beats the state-of-art methods using an extensive set of simulations. The quantitative comparison is made for the metrics such as packet delivery ratio, detection probability, throughput, energy consumption, transaction success rate, resilience, attack frequency which enhances the trust, privacy and security in SIoT network.
