Leaky Frontends: Security Vulnerabilities in Processor Frontends

2021 · arXiv (Cornell University)

This paper evaluates new security threats due to the processor frontend in modern Intel processors. The root causes of the security threats are the multiple paths in the processor frontend that the micro-operations can take: …

Snowball Adversarial Attack on Traffic Sign Classification

2025 · arXiv (Cornell University)

Adversarial attacks on machine learning models often rely on small, imperceptible perturbations to mislead classifiers. Such strategy focuses on minimizing the visual perturbation for humans so they are not confused, and also maximizing the misclassification …
