Ellipsis: Towards Efficient System Auditing for Real-Time Systems
Ayoosh Bansal, Anant Kandikuppa, Chien-Ying Chen +3
System auditing is a powerful tool that provides insight into the nature of suspicious events in computing systems, allowing machine operators to detect and subsequently investigat…
SchedGuard: Protecting against Schedule Leaks Using Linux Containers
Jiyang Chen, Tomasz Kloda, Ayoosh Bansal +6
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 ra…
On Scheduler Side-Channels in Dynamic-Priority Real-Time Systems
Chien-Ying Chen, Sibin Mohan, Rodolfo Pellizzoni +1
While the existence of scheduler side-channels has been demonstrated recently for fixed-priority real-time systems (RTS), there have been no similar explorations for dynamic-priori…
A Novel Side-Channel in Real-Time Schedulers
Chien-Ying Chen, Sibin Mohan, Rodolfo Pellizzoni +2
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, av…
REORDER: Securing Dynamic-Priority Real-Time Systems Using Schedule Obfuscation
Chien-Ying Chen, Monowar Hasan, AmirEmad Ghassami +2
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…
A Reconnaissance Attack Mechanism for Fixed-Priority Real-Time Systems
Chien-Ying Chen, AmirEmad Ghassami, Sibin Mohan +4
In real-time embedded systems (RTS), failures due to security breaches can cause serious damage to the system, the environment and/or injury to humans. Therefore, it is very import…
Restart-Based Security Mechanisms for Safety-Critical Embedded Systems
Fardin Abdi, Chien-Ying Chen, Monowar Hasan +3
Many physical plants that are controlled by embedded systems have safety requirements that need to be respected at all times - any deviations from expected behavior can result in d…
