Applications of Dynamic Trust Management Model in Agricultural Scientific Data Security

[Purpose/Significance] In order to meet the needs of intensive agricultural data research, the security protection of agricultural data needs to be developed in a dynamic and adaptive direction. Trust management is one of the core means to ensure data security, the dynamic research and application exploration of its management model is of great significance. [Method/Process] This paper reviews the development process and theoretical framework of dynamic trust management model, analyzes the characteristics of the whole life cycle of agricultural data, summarizes the practical needs of trust management of agricultural data, and expounds the rationality and feasibility of practicing the dynamic trust management model in the field of agricultural data security. On the basis of the above research, combined with the business characteristics of agricultural research itself, this paper explores the application methods and key points of dynamic trust management model in the field of agricultural data security from the aspects of user trust, equipment trust and application trust. [Results/Conclusions] At the end of this paper, the application prospect and future development direction of dynamic trust management model are prospected. The possibility and necessity of expansion and development of a dynamic trust management model to dynamic traffic management and dynamic authorization management, as well as combining with SDP, are discussed.
