Abstract
The detection of covert channels in an information flow model is a practical problem in determining whether the security guarantees of the operation system have been achieved. Asbestos system is a typical information confidentiality protection system. This poster introduces a formal approach to automatically detect covert channels in Asbestos systems. The approach innovatively generalizes a CSP (Communicating Sequential Process) based formal description of Asbestos system and utilizes Ray’s noninterference Equivalence in the detection of covert channels. The covert channels are automatically detected by employing a CSP based model checking tool FDR2.
