BitFlipScope: Scalable Fault Localization and Recovery for Bit-Flip Corruptions in LLMs
Muhammad Zeeshan Karamat, Sadman Saif, Christiana Chamon Garcia
Large Language Models (LLMs) deployed in practical and safety-critical settings are increasingly susceptible to bit-flip faults caused by hardware degradation, cosmic radiation, or…
Adapting Noise-Driven PUF and AI for Secure WBG ICS: A Proof-of-Concept Study
Devon A. Kelly, Christiana Chamon
Wide-bandgap (WBG) technologies offer unprecedented improvements in power system efficiency, size, and performance, but also introduce unique sensor corruption and cybersecurity ri…
Noise-Based Authentication: Is It Secure?
Sarah A. Flanery, Christiana Chamon
This paper introduces a three-point biometric authentication system for a blockchain-based decentralized identity network. We use existing biometric authentication systems to demon…
Image Scaling Attack Simulation: A Measure of Stealth and Detectability
Devon A. Kelly, Sarah A. Flanery, Christiana Chamon
Cybersecurity practices require effort to be maintained, and one weakness is a lack of awareness regarding potential attacks not only in the usage of machine learning models, but a…
