Function-Oriented Programming: A New Class of Code Reuse Attack in C Applications

2018

Control-hijacking attacks include code injection attacks and code reuse attacks. In recent years, with the emergence of the defense mechanism data-execution prevention(DEP), code reuse attacks have become mainstream, such as return-oriented programming(ROP), Jump-Oriented Programming(JOP), and …

Zipper Stack: Shadow Stacks Without Shadow

2019 · arXiv (Cornell University)

Return-Oriented Programming (ROP) is a typical attack technique that exploits return addresses to abuse existing code repeatedly. Most of the current return address protecting mechanisms (also known as the Backward-Edge Control-Flow Integrity) work only in …

Exploring the Impact of Data Quantity on ASR in Extremely Low-resource Languages

2024 · arXiv (Cornell University)

This study investigates the efficacy of data augmentation techniques for low-resource automatic speech recognition (ASR), focusing on two endangered Austronesian languages, Amis and Seediq. Recognizing the potential of self-supervised learning (SSL) in low-resource settings, we …

DiceHuBERT: Distilling HuBERT with a Self-Supervised Learning Objective

2025 · arXiv (Cornell University)

We introduce DiceHuBERT, a knowledge distillation framework for compressing HuBERT, a widely used self-supervised learning (SSL)-based speech foundation model. Unlike existing distillation methods that rely on layer-wise and feature-wise mapping between teacher and student models, …
