Control systems can be vulnerable to security threats where an attacker gathers information
about the execution of the system. In particular, side-channel attacks exploit the predictability …

Schedule randomization is one of the recently introduced security defenses against
schedule-based attacks, ie, attacks whose success depends on a particular ordering …

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 …

Recent work has shown that the timing behavior of a real-time system can be utilized by
attackers for various adverse purposes via schedule-based timing side-channel attacks. An …

The secure functioning of automotive systems is vital to the safety of their passengers and
other roadway users. One of the critical functions for safety is the controller area network …

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 …

Increasing internet connectivity poses an existential threat for cyber-physical systems.
Securing these safety-critical systems becomes an important challenge. Cyber-physical …

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 …

Industrial control systems (ICSs) consist of a large number of control applications that are
associated with periodic real-time flows with hard deadlines. To facilitate large-scale …

In this paper, we investigate the impact of priority assignment on schedule-based attacks in
fixed-priority real-time systems. Through the schedule-based attacks, attackers may …
