PriSrv: Privacy-Enhanced and Highly Usable Service Discovery in Wireless Communications
Yang Yang, Robert H. Deng, Guomin Yang +5
Service discovery is essential in wireless communications. However, existing protocols provide limited privacy protection, leaking sensitive device information and opening routes t…
Developing a Strong CPS Defender: An Evolutionary Approach
Qingyuan Hu, Christopher M. Poskitt, Jun Sun +1
Cyber-physical systems (CPSs) are used extensively in critical infrastructure, underscoring the need for anomaly detection systems that are able to catch even the most motivated at…
Out of Distribution, Out of Luck: How Well Can LLMs Trained on Vulnerability Datasets Detect Top 25 CWE Weaknesses?
Yikun Li, Ngoc Tan Bui, Ting Zhang +16
Automated vulnerability detection research has made substantial progress, yet its real-world impact remains limited. Prior work found that current vulnerability datasets suffer fro…
