Abstract

Objective: The proliferation of internet results in exponential increase of the connected devices across the globe. These devices are continuously communicating with each other for several computational and information exchange tasks. These connected devices belong to IoT network and are also known as devices everywhere, anywhere. Methods: These IoT devices establish connection with each other for performing the desired computational tasks. Though, IoT devices are ubiquitous in nature, however, security and privacy remains a concern while establishing communication. To overcome these concerns, trust management is required before initiating communication among these devices. Trust management is domain where privacy of IoT devices is preserved and simultaneously ensuring security objectives in the IoT network. Research authors have proposed numerous models on trust management based on fuzzy logic. Findings: Our research scope is to propose a trust management model based on sociological aspects of users. In this paper, we have inclusively considered SIoT network for developing a deterministic model which can explicitly mention the trustworthiness of guest devices as determined by the host device. The determination is supported by the logical expression and is based on social attributes of the SIoT device, severity of the computational task and computational incentive of the task. Application: We present the model including the flowchart and algorithm supported by truth table. Our model is light weight and deterministic in nature which can be implemented by digital logic in the devices.
