A Survey of Trust Management for IoT

The Internet of Things (IoT) is extremely influencing our daily lives in many areas, covering small devices to large network systems. An IoT system may be a group of directing rules that rearranges the usage of IoT applications. This paper details a trust management model and security of IoT systems. Trust management models and security play a critical part in IoT to shield information and devices from attacks since it supplies security for all layers and networks. This review focuses on how a trust management model features a big function in IoT in enhancing reliability, privacy, and security. During this survey, we explained the challenges alongside the solutions in terms of IoT security and privacy and recognized the foremost security problem within the IoT framework. Additionally, this paper explored the characteristics of trust and distinguished some IoT security challenges, explaining how middleware can affect the protection of IoT.
