Work in Progress: Security-Aware Preemptive Scheduling with Partial Trust for Safety-Critical Embedded Systems

Safety-critical embedded systems often have very limited computational capabilities that must be carefully managed to provide the required functionalities. Since such systems are increasingly becoming a target of attacks, there is a need for real-time resource-allocation techniques that are resistant to such attacks. We extend the widely used sporadic task model to additionally enable the representation of certain kinds of security requirements, develop a corresponding scheduling algorithm and associated schedulability test, and experimentally evaluate the effectiveness of our proposed algorithm and test.
