Don't Listen To Me: Understanding and Exploring Jailbreak Prompts of Large Language Models

no code implementations26 Mar 2024 Zhiyuan Yu, Xiaogeng Liu, Shunning Liang, Zach Cameron, Chaowei Xiao, Ning Zhang

Building on the insights from the user study, we also developed a system using AI as the assistant to automate the process of jailbreak prompt generation.

Beamforming Design for Double-Active-RIS-aided Communication Systems with Inter-Excitation

no code implementations17 Mar 2024 Boshi Wang, Cunhua Pan, Hong Ren, Zhiyuan Yu, Yang Zhang, Mengyu Liu, Gui Zhou

Due to the signal amplification capability of active RISs, the mutual influence between active RISs, which is termed as the "inter-excitation" effect, cannot be ignored.

Automatic and Universal Prompt Injection Attacks against Large Language Models

1 code implementation7 Mar 2024 Xiaogeng Liu, Zhiyuan Yu, Yizhe Zhang, Ning Zhang, Chaowei Xiao

Large Language Models (LLMs) excel in processing and generating human language, powered by their ability to interpret and follow instructions.

Reconfigurable Intelligent Surface assisted Integrated Communication, Sensing, and Computation Systems

no code implementations21 Feb 2024 Jiahua Wan, Hong Ren, Zhiyuan Yu, Zhenkun Zhang, Yang Zhang, Cunhua Pan, Jiangzhou Wang

To address the formulated non-convex problem, we propose an algorithm based on the block coordinate descent (BCD) method to decouple the original problem into two subproblems, where the computational and beamforming settings are optimized alternately.

Joint Beamforming Design for Double Active RIS-assisted Radar-Communication Coexistence Systems

no code implementations7 Feb 2024 Mengyu Liu, Hong Ren, Cunhua Pan, Boshi Wang, Zhiyuan Yu, Ruisong Weng, Kangda Zhi, Yongchao He

However, when radar and communication equipment coexist in the same system, i. e. radar-communication coexistence (RCC), the interference from communication systems to radar can be large and cannot be ignored.

Secure Wireless Communication in Active RIS-Assisted DFRC System

no code implementations3 Feb 2024 Yang Zhang, Hong Ren, Cunhua Pan, Boshi Wang, Zhiyuan Yu, Ruisong Weng, Tuo Wu, Yongchao He

This work considers a dual-functional radar and communication (DFRC) system with an active reconfigurable intelligent surface (RIS) and a potential eavesdropper.
