Framework for building secure real-time systems

Computer security must be a hot issue nowadays. Among many systems, real-time system is what can be most seriously damaged by security violations, like Denial of Services, because of its time constraints for the services. Despite many researches, most of them depend on only the matters of how we invent and how we adopt more secure countermeasures, which is not enough to guarantee secure systems. This mainly due to the lack of unified and systematic way of building secure systems. This paper provides an integrated guideline for increasing security of systems. We can use this guideline as a framework for building secure real-time systems.
