Real-time hierarchical scheduling facilitates modular reasoning about the temporal behavior of real-time applications by isolating their potential misbehavior. However, conventional time-partitioning mechanisms fail to achieve strong temporal isolation from a security viewpoint; variations in execution timings can be perceived by others, enabling illegitimate information-flow between applications completely isolated from each other in the utilization of CPU time. This project develops algorithmic solutions that make real-time partitions oblivious of others��� varying temporal behaviors, achieving non-interference-based security among partitions. The proposed work will allow such systems to employ advanced hardware and software technologies to develop high-end, real-time applications in a secure manner.
