An Enhanced Dynamic Trust Model Based on Power Internet of Things

In recent years, with the rapid development of Internet of Things technology, there are certain security risks in the communication between nodes within each system and some intelligent devices and Internet of Things terminals have been affected. As an evaluation method of trust and security, trust model has attracted much attention. This paper is in the view of the existing trust models which are weak in the dynamic adaption and feedback. This paper proposes a time attenuation factor, an event impact factor and the reward mechanism. The model largely improves the dynamic adaptability of trust model and the use of feedback ability.
