About

Lezhong Xu is a leading researcher in the security and control of cyber-physical systems (CPSs), with a particular focus on defending against denial-of-service (DoS) attacks. His work addresses the critical challenge of maintaining system stability and security when communication channels are maliciously disrupted. Xu’s major contributions include developing novel security analysis frameworks and control strategies for CPSs under both periodic and aperiodic DoS attacks. His 2023 paper on "Security Analysis and Control Under Periodic DoS Attacks" (23 citations) introduced a periodic attack model that accounts for limited adversary energy, while his 2024 work on "Event-Triggered Secure Control Under Aperiodic DoS Attacks" (19 citations) pioneered event-based mechanisms to conserve communication resources while ensuring resilience. These highly cited papers have established Xu as a key figure in the rapidly growing field of CPS security, providing foundational tools for designing robust control systems that can withstand sophisticated cyberattacks. His research is particularly valuable for applications in critical infrastructure, autonomous systems, and industrial control networks where security and reliability are paramount.
