Abstract:	The access control begins to be widely discussed, especially in organizations and systems with a hierarchical structure. In such a hierarchy, users and their information items divide into a number of disjointed sets of security classes, and to access files and documents depends on the user’s privilege. Now, many existing key assignment schemes for solving access control problems cannot exceptionally work because of the lack of flexibility. In this paper, the authors propose a simple key assignment scheme which can be performed in a user hierarchy and also can efficiently generate and derive security keys. Besides, due to the efficient dynamic key management, the scheme can be easily implemented in a realistic environment.
