AI agents that autonomously execute tool calls on a user's behalf raise pressing questions about permission management: what role could users play, and what role should they play?…
Extending the Formalism and Theoretical Foundations of Cryptography to AI
Federico Villa, F. Betül Durak, Tadayoshi Kohno +2
Recent progress in (Large) Language Models (LMs) has enabled the development of autonomous LM-based agents capable of executing complex tasks with minimal supervision. These agents…
Towards Automating Data Access Permissions in AI Agents
Yuhao Wu, Ke Yang, Franziska Roesner +3
As AI agents attempt to autonomously act on users' behalf, they raise transparency and control issues. We argue that permission-based access control is indispensable in providing m…

Rachel McAmis, Gregor Haas, Mattea Sim +2
Satellites face a multitude of security risks that set them apart from hardware on Earth. Small satellites may face additional challenges, as they are often developed on a budget a…
IsolateGPT: An Execution Isolation Architecture for LLM-Based Agentic Systems
Yuhao Wu, Franziska Roesner, Tadayoshi Kohno +2
Large language models (LLMs) extended as systems, such as ChatGPT, have begun supporting third-party applications. These LLM apps leverage the de facto natural language-based autom…
Developing Story: Case Studies of Generative AI's Use in Journalism
Natalie Grace Brigham, Chongjiu Gao, Tadayoshi Kohno +2
Journalists are among the many users of large language models (LLMs). To better understand the journalist-AI interactions, we conduct a study of LLM usage by two news agencies thro…
