Protecting Security-Critical Real-Time Systems against Fault Attacks in Many-Core Platforms

Authors:A. NorollahZ. KazemiD. DerafshiH. BeitollahiM. Fazeli

Security-critical real-time systems are moving from single-core to many-core platforms, and that shift opens the door to fault injection attacks that slow tasks down or make the system fail. This paper proposes an online, security-aware hardware scheduler that defends against them by replicating tasks: critical tasks and their copies are scheduled independently in hardware with the Least Slack Time first algorithm, under real-time constraints. Whether every task still meets its deadline is answered in the paper.
