Abstract

A formal language to specify general access control policies and their sequences of transformations has been proposed in [1]. The access control policy was specified by a domain description which consisted of a finite set of initial policy propositions, policy transformation propositions and default propositions. Usually, access control models are falls into two conventional categories: discretionary access control(DAC) and mandatory access control(MAC). Traditional DAC models basically enumerate all the subjects and objects in a system and regulate the access to the object based on the identity of the subject. It can be best represented by the HRU's access control matrix [4]. While on the other hand, MAC models are lattice based models, in the sense that each subject and object is associated with a sensitivity level which forms a lattice
