The main contributions of this paper are: (1) a scheme for access control systematically applied at the fine-grained level of each elementary operation, (2) a novel proof of authorization concept and flexible authorization delegation technique, and (3) the design and proof-of-concept implementation of an intrusion-tolerant prototype of the authorization architecture.
