[email protected] Various kinds of applications have been developed by using object-oriented technologies. Objectoriented systems are composed of multiple objects which cooperate to achieve some objectives by message passing mechanisms. The Common Object Request Broker Architecture (CORBA) is now getting a standard framework for realizing the interoperability of distributed applications. In addition to realizing the interoperability, the system have to be secure. In the secure systems, it is required to not only protect objects from illegally accessed but also prevent illegal information ow among objects. In this paper, we discuss a high assurance access control model for object-oriented systems. E-mail
