Abstract

The present invention provides a multi-granularity distributed information stream control method and system. The method comprises a first step of setting a multi-granularity control category list, wherein the multi-granularity control category list comprises multiple control categories, and performing multi-granularity access control on the data according to a corresponding control category, wherein each control category is corresponding to a global level control and a global process level control; and a second step of creating a global capability table and a fine-grained capability table, setting an information stream control rule, and performing multi-granularity multi-strength access control on the data according to the global capability table, the fine-grained capability table, and the information stream control rule, wherein the global capability table is used for granting a coarse-grained capability, and is corresponding to the multi-granularity control category list. A multi-granularity capability granting scheme is added based on a distributed information stream model, so that the global coarse-grained data can be isolated and protected conveniently, and the fine-grained data can be shared. The method integrates advantages of both a traditional access control model and the distributed information stream control model.

Description

technical field

[0001] The invention relates to access control, in particular to a multi-granularity distributed information flow control method and system. Background technique

[0002] Due to its basic status in practical applications, data security has become the most urgent problem to be broken through and solved.

[0003] In the process of research and practice, the inventors of the present invention found that: traditional access control models such as the autonomous access control model, the basic unit of authority granting is the user, the control granularity is relatively coarse, but the management is convenient and there are many practical applications; distributed information flow control The model can control the behavior of the process level, and the control granularity is finer, but the management is complicated, and the actual application is relatively few. Contents of the invention

[0004] Aiming at the deficiencies of the prior art, the present invention...
