Our research demonstrates the existence of side-channel information leaks in TrustZone-
enabled real-time systems. Our algorithm can infer the critical tasks' arrival times and …

We demonstrate the presence of a novel scheduler side-channel in preemptive, fixed-priority
real-time systems (RTS); examples of such systems can be found in automotive systems …

Scheduler side-channels can leak critical information in real-time systems, thus posing
serious threats to many safety-critical applications. The main culprit is the inherent …

Real-time systems have recently been shown to be vulnerable to timing inference attacks,
mainly due to their predictable behavioral patterns. Existing solutions such as schedule …

Embedded real-time systems are widely adopted in safety-critical domains such as aircrafts,
automobiles and space vehicles. Unfortunately, with the sharp rise in the use of common-off …

An accurate sense of elapsed time is essential for the safe and correct operation of
hardware, software, and networked systems. Unfortunately, an adversary can manipulate …

Many real-time systems are safety-critical, where reliability is crucial. Under traditional
scheduling mechanism, the execution patterns of the tasks on such system can be easily …

The deterministic (timing) behavior of real-time systems (RTS) can be used by adversaries-
say, to launch side channel attacks or even destabilize the system by denying access to …

Real-time computing systems are those that are designed to achieve computing goals by
certain deadlines. Real-time computing systems are present in everything from cars to …

Safety-critical real-time systems, including real-time cyber-physical and industrial control
systems, need not be solely correct but also timely. Untimely (stale) results may have severe …
