Suppose that a system has 1000 objects and I00 domains at some time. 1% of the ob jects are accessible (some combination of r, w and x) in all domains, 10% are ac cessible in two domains, and the remaining 89% are accessible in only one domain. Suppose one unit of space is required to store an access right (some combination of r, w, x), object ID, or a domain ID. How much space is needed to store the full protec tion matrix, protection matrix as ACL, and protection matrix as capability
