We believe that a practical access control scheme should support access control in a lattice where users and resources are both together grouped into partially ...
This lattice consists of the four linearly ordered security levels TS > S > C>U, and eight categories {A, K, L, Q, W, X, Y, Z} corresponding to, say, eight ...
