摘　　要：[目的/意义]为适应数据密集型农业科研范式的需要,农业科学数据的安全防护亟需向着动态化、自适应的方向发展。信任管理是保障数据安全的核心手段之一,其管理模型的动态化研究和应用探索具有十分重要的意义。[方法/过程]本文梳理了动态信任管理模型的发展历程和理论框架,分析了农业科学数据全生命周期的业务特点,总结了农业科学数据信任管理的现实需求,阐述了在农业科学数据安全领域实践动态信任管理模型的合理性和可行性。在此基础上,结合农业科研本身的业务特征,从用户信任、设备信任和应用信任3个层面探索了动态信任管理模型在农业科学数据安防领域的应用方法和要点。[结果/结论]研究展望了动态信任管理模型的应用前景和未来的发展方向,讨论了动态信任管理模型向动态流量管理和动态授权管理扩展以及和SDP相结合的可能性和必要性。[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.
