A Review on Trust Management in the Social Internet of Things: Issues and Challenges

Abstract

In today's era, every electrical and electronic device is connected very intelligently. These electronic devices like sensors, RFIDs, actuators are becoming an important part of the structure. It is required to connect to the internet. Internet is used in every aspect of daily life. There are drastic changes in the usage of the most demanding and useful technology known as the Internet of Things (IoT). In this field, IoT has been shown one of the important which connect various physical objects with the internet with unique identification. Billions of objects are enabled with the internet and interconnected with each other to interface with Human-to-Machine or Machine-to-Machine to take decisions of data transaction without human involvement. This internet enables devices connected to our social life which is terme as Social Internet of Things (SIoT). Hence we can say SIoT is an expansion IoT. People and things are connected with social networks which are known as Human to Things (H2T) interactions. Some of the devices are authentic and some are suspicious. The essential utilization of services within SIoT makes a secured network closely rely on origin of services (Service provider) and services accesed by end terminal (Service requester). Due to a lack of trust technologies, trust SIoT is still not so much popular in the market as demanding technology for the researcher and developer. Device owners are worried about sharing the data or receiving any information. Therefore, trust devices are required to identify in the connected network..Hence minimization of risk and uncertaintity within the system are analyse by the degree of trust for Particular Trust Management System(TMS).Trust and Trustworthiness are novel fields in social networking environment clearlify by investigating the research article under SIoT. In present paper, our contribution starts with the introduction and then is further fragmented in three phases.The first phase represent the basic of trust and SIoT. Second phase categorizes the trust management solutions from the literature review. The third phase identifies and discuses issues, challenges and requirement in current scenario of SIoT and also depicts how developing trust and trustworthiness among social devices interaction as challenging task.
