Preventing Timing Side-Channels via Security-Aware Just-In-Time Compilation

2022 · arXiv (Cornell University)

Recent work has shown that Just-In-Time (JIT) compilation can introduce timing side-channels to constant-time programs, which would otherwise be a principled and effective means to counter timing attacks. In this paper, we propose a novel …

LaserGuider: A Laser Based Physical Backdoor Attack against Deep Neural Networks

2024 · arXiv (Cornell University)

Backdoor attacks embed hidden associations between triggers and targets in deep neural networks (DNNs), causing them to predict the target when a trigger is present while maintaining normal behavior otherwise. Physical backdoor attacks, which use …
