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…
ChipletQuake: On-die Digital Impedance Sensing for Chiplet and Interposer Verification
Saleh Khalaj Monfared, Maryam Saadat Safa, Shahin Tajik
The increasing complexity and cost of manufacturing monolithic chips have driven the semiconductor industry toward chiplet-based designs, where smaller and modular chiplets are int…
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…
The Reversing Machine: Reconstructing Memory Assumptions
Mohammad Sina Karvandi, Soroush Meghdadizanjani, Sima Arasteh +5
Existing anti-malware software and reverse engineering toolkits struggle with stealthy sub-OS rootkits due to limitations of run-time kernel-level monitoring. A malicious kernel-le…
