Abstract

En 中文

The rapid progress in computer, communication, and sensor technology has led to the proliferation of cyber-physical systems (CPSs) which have become integral to various sectors. However, their heavy dependence on open communication networks makes them vulnerable to network-based attacks. To tackle these security concerns, this paper delves into game learning-based system identification with binary-valued observations in the presence of Denial-of-Service (DoS) attacks. We first formulate a game model to capture interactions between the attacker and defender. Focusing on piecewise constant DoS attacks, we then devise a defense strategy grounded in game learning principles. This strategy paves the way for crafting estimation algorithms for both the attack strategy and system parameters, with their performance scrutinized in specific stages. Through meticulous analysis and comprehensive numerical simulations, we have observed that the game learning approach outperforms the randomly selected defense strategy in terms of parameter estimation. This provides a novel and reliable approach to address security challenges within CPSs.
