Timing and Memory Telemetry on GPUs for AI Governance
Saleh K. Monfared, Fatemeh Ganji, Dan Holcomb +1
The rapid expansion of GPU-accelerated computing has enabled major advances in large-scale artificial intelligence (AI), while heightening concerns about how accelerators are obser…
Chypnosis: Undervolting-based Static Side-channel Attacks
Kyle Mitard, Saleh Khalaj Monfared, Fatemeh Khojasteh Dana +3
Static side-channel analysis attacks, which rely on a stopped clock to extract sensitive information, pose a growing threat to embedded systems' security. To protect against such a…
Rubber Mallet: A Study of High Frequency Localized Bit Flips and Their Impact on Security
Andrew Adiletta, Zane Weissman, Fatemeh Khojasteh Dana +2
The increasing density of modern DRAM has heightened its vulnerability to Rowhammer attacks, which induce bit flips by repeatedly accessing specific memory rows. This paper present…
There's Waldo: PCB Tamper Forensic Analysis using Explainable AI on Impedance Signatures
Maryam Saadat Safa, Seyedmohammad Nouraniboosjin, Fatemeh Ganji +1
The security of printed circuit boards (PCBs) has become increasingly vital as supply chain vulnerabilities, including tampering, present significant risks to electronic systems. W…
Logical Maneuvers: Detecting and Mitigating Adversarial Hardware Faults in Space
Fatemeh Khojasteh Dana, Saleh Khalaj Monfared, Shahin Tajik
Satellites are highly vulnerable to adversarial glitches or high-energy radiation in space, which could cause faults on the onboard computer. Various radiation- and fault-tolerant…
LaserEscape: Detecting and Mitigating Optical Probing Attacks
Saleh Khalaj Monfared, Kyle Mitard, Andrew Cannon +2
The security of integrated circuits (ICs) can be broken by sophisticated physical attacks relying on failure analysis methods. Optical probing is one of the most prominent examples…
