Incorporation of security and fault tolerance mechanisms into real-time component-based distributed computing systems

The volume and size of real-time (RT) distributed computing (DC) applications are now growing faster than in the last century. The mixture of application tasks running on such systems is growing as well as the shared use of computing and communication resources for multiple applications including RT and non-RT applications. The increase in use of shared resources accompanies with it the need for effective security enforcement. More specifically, the needs are to prevent unauthorized users: (1) from accessing protected information; and (2) from disturbing bona-fide users in getting services from server components. Such disturbances are also called denial-of-service attacks.
