We are considering a radically different approach to binary reverse engineering tools by placing the recompilability as the first and topmost goal. We will further develop our preliminary study on Reassembleable Disassembling, with the similar design goal to preserve the recompilability while lifting the code to higher level languages or intermediate representations.   Learn more...

This project tackles the challenge of binary code analysis by proposing several advanced methods that combine techniques from behavior and semantics perspectives. The proposed methods leverage formal program semantics, symbolic execution, automated constraint solving, and algorithmic memorization of code semantics that form solid foundations with rigorous resilience properties to latest attacks.

This multi-disciplinary project aims to develop novel technology that will enable people to regain a sense of control by enabling them to simply ask questions about the privacy issues that matter to them rather than requiring them to read long, one-size-fits all privacy policies. This multi-disciplinary project aims to re-invent notice and choice, moving from long and hard-to-understand notices to interactive privacy dialogues with users. Learn more...

The goal of this project is first to learn an adversarial agent informed by explainable AI. Using this learned agent, we then unveil the weakness of target agents and adversarially train them accordingly. Through a robustness check, we evaluate the enhanced agents. If a strengthened agent fails the adversary-resistance check, we fall back on formal verification and program synthesis techniques. Learn more...

In this project, we propose a flexible framework, named as SAGA, where scholars can easily create cybersecurity case studies (similar to business case studies) that have AI components. Further, by adopting the notion of “citation” in academic world and implementing it using public platforms (e.g., arXiv, Github, Kaggle), SAGA enables the developed case studies to be easily found and shared in the community, and the authors of case studies to be rightfully attributed for their efforts, thereby encouraging more participation from scholars in creating and sharing case studies.

This research project seeks to address privacy issues by developing a new location privacy framework for workers in vehicle-based spatial crowdsourcing. The project will start with developing new adversarial models to capture the network-constrained mobility features of multiple vehicles operating over roads. As a countermeasure of the adversarial models, the project will develop a new location obfuscation paradigm that can effectively protect vehicles' location privacy even assuming that adversaries use vehicles' mobility features for inference attacks.

The proposed work will develop tools to provide users with the information and the backend support they need to reclaim control of their experience on social media. The Sociolinguistic Information Filtering Tool (SIFT) will consist of a desktop extension and associated mobile app initially based on machine learning, natural language processing and network theory techniques. Motivated by recent work understanding human information processing in the context of warning mechanisms, the project will build these tools iteratively, with humans-in-the-loop via in-depth user studies. Proposed work will evaluate and refine algorithmic approaches for account filtering and user-initiated bulk action toward automated, malicious, or otherwise unwanted accounts. Learn more...
