The invention discloses a dynamic authorization method and device based on trusted measurement, equipment and a storage medium, and relates to the technical field of cloud computing. The method comprises the steps of obtaining operation information associated with file operation in the process of executing the file operation; determining the credibility of the file operation according to the operation information; and dynamically authorizing the authorization subject to which the file operation belongs based on the credibility of the file operation. According to the technical scheme, the full life cycle of user operation can be monitored, dynamic authorization is carried out on the authorization subject based on the file operation credibility, and it is guaranteed that the bottom storage HDFS is in a credible state all the time. 本发明公开了一种基于可信度量的动态授权方法、装置、设备及存储介质，涉及云计算技术领域。该方法包括：在执行文件操作过程中，获取与文件操作关联的操作信息；依据操作信息，确定文件操作的可信度；基于文件操作的可信度，对文件操作所属授权主体进行动态授权。本发明实施例的技术方案，可以对用户操作的全生命周期进行监控，并基于文件操作可信度为授权主体进行动态授权，保证底层存储HDF
