This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-Physical Systems (CPS) are physical processes that are tightly integrated with computation and communication systems for monitoring and control. Advances in CPS design has equipped them with adaptability, resiliency, safety, and security features that exceed the simple embedded systems of the past. On the other hand, the design of CPS involving complex interconnections between modules often leaves open several points for attackers to strike. This PhD dissertation is aimed upon developing theoretical techniques and building simulation tools based on distributional robustness for uncertainty handling tailored for guaranteeing resiliency in attack-prone CPS. As these systems become large, devising both model-based and moment-based methods for detecting anomalies are critical for robust and efficient operation. Similarly, safely deploying robots in dynamic and unknown environments require a systematic accounting of various risks both within and across layers in an autonomy stack from perception to motion planning and control. However, the perception and planning components in a robot autonomy stack are loosely coupled, in the sense that nominal estimates from the perception system may be used for planning, while inherent perception uncertainties are usually ignored, inspired from the classical separation of estimation and control in linear systems theory. As motion planning algorithms must be coupled with the outputs of inherently uncertain perception systems, there is a crucial need for tightly coupled perception and planning frameworks that explicitly incorporate perception uncertainties. In the first contribution of this dissertation, we show that robotic networks having graph robustness properties guaranteeing resiliency against malicious agents can be compromised through spoofing attack. We quantify the misclassification probability through distributionally robust pairwise comparison of the physical fingerprints of the agents. We propose a variant of robust consensus protocol to guarantee spoof resiliency against malicious agents who might spoof arbitrary amounts of spoofed identities. In the second contribution of this dissertation, we design anomaly detector for cyber-physical systems. Threshold of an anomaly detector limits the potential impact of a stealthy attacker attacking a CPS. We show that the traditional chi-squared anomaly detector raises false alarms more than a desired value in face of non-Gaussian uncertainties. To address the above problem, we propose a distributionally robust approach for tuning anomaly detector threshold and further analyse the problem when the system model has multiplicative noise uncertainties. In the final contribution of this dissertation, we establish a systematic framework for integrating the perception and control components, tailored for the robotic systems that are designed to operate in dynamic, cluttered and unknown environments. We propose a distributionally robust incremental sampling-based motion planning framework that explicitly and coherently incorporates perception and prediction uncertainties. We formulate distributionally robust risk constraints through linear temporal logic specifications to help the robot make coherent risk assessment without increasing the computation complexity while operating in unknown environments.

This book was released on 2020-11-16 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a cross-layer design to achieve security and resilience for CPSs (Cyber-Physical Systems). The authors interconnect various technical tools and methods to capture the different properties between cyber and physical layers. Part II of this book bridges the gap between cryptography and control-theoretic tools. It develops a bespoke crypto-control framework to address security and resiliency in control and estimation problems where the outsourcing of computations is possible. Part III of this book bridges the gap between game theory and control theory and develops interdependent impact-aware security defense strategies and cyber-aware resilient control strategies. With the rapid development of smart cities, there is a growing need to integrate the physical systems, ranging from large-scale infrastructures to small embedded systems, with networked communications. The integration of the physical and cyber systems forms Cyber-Physical Systems (CPSs), enabling the use of digital information and control technologies to improve the monitoring, operation, and planning of the systems. Despite these advantages, they are vulnerable to cyber-physical attacks, which aim to damage the physical layer through the cyber network. This book also uses case studies from autonomous systems, communication-based train control systems, cyber manufacturing, and robotic systems to illustrate the proposed methodologies. These case studies aim to motivate readers to adopt a cross-layer system perspective toward security and resilience issues of large and complex systems and develop domain-specific solutions to address CPS challenges. A comprehensive suite of solutions to a broad range of technical challenges in secure and resilient control systems are described in this book (many of the findings in this book are useful to anyone working in cybersecurity). Researchers, professors, and advanced-level students working in computer science and engineering will find this book useful as a reference or secondary text. Industry professionals and military workers interested in cybersecurity will also want to purchase this book.

Download or read book Robust Model Predictive Control of Resilient Cyber physical Systems written by Qi Sun and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-physical systems (CPS), integrating advanced computation, communication, and control technologies with the physical process, are widely applied in industry applications such as smart production and manufacturing systems, robotic and automotive control systems, and smart grids. Due to possible exposure to unreliable networks and complex physical environments, CPSs may simultaneously face multiple cyber and physical issues including cyber threats (e.g., malicious cyber attacks) and resource constraints (e.g., limited networking resources and physical constraints). As one of the essential topics in designing efficient CPSs, the controller design for CPSs, aiming to achieve secure and resource-aware control objectives under such cyber and physical issues, is very significant yet challenging. Emphasizing optimality and system constraint handling, model predictive control (MPC) is one of the most widely used control paradigms, notably famous for its successful applications in chemical process industry. However, the conventional MPC methods are not specifically tailored to tackle cyber threats and resource constraints, thus the corresponding theory and tools to design the secure and resource-aware controller are lacking and need to be developed. This dissertation focuses on developing MPC-based methodologies to address the i) secure control problem and ii) resource-aware control problem for CPSs subject to cyber threats and resource constraints. In the resource-aware control problem of CPSs, the nonlinear system with additive disturbance is considered. By using an integral-type event-triggered mechanism and an improved robustness constraint, we propose an integral-type event-triggered MPC so that smaller sampling frequency and robustness to the additive disturbance can be obtained. The sufficient conditions for guaranteeing the recursive feasibility and the closed-loop stability are established. For the secure control problem of CPSs, two aspects are considered. Firstly, to achieve the secure control objective, we design a secure dual-mode MPC framework, including a modified initial feasible set and a new positively invariant set, for constrained linear systems subject to Denial-of-Service (DoS) attacks. The exponential stability of the closed-loop system is guaranteed under several conditions. Secondly, to deal with cyber threats and take advantage of the cloud-edge computing technology, we propose a model predictive control as a secure service (MPCaaSS) framework, consisting of a double-layer controller architecture and a secure data transmission protocol, for constrained linear systems in the presence of both cyber threats and external disturbances. The rigorous recursive feasibility and robust stability conditions are established. To simultaneously address the secure and resource-aware control problems, an event-triggered robust nonlinear MPC framework is proposed, where a new robustness constraint is introduced to deal with additive disturbances, and a packet transmission strategy is designed to tackle DoS attacks. Then, an event-triggered mechanism, which accommodates DoS attacks occurring in the communication network, is proposed to reduce the communication cost for resource-constrained CPSs. The recursive feasibility and the closed-loop stability in the sense of input-to-state practical stable (ISpS) are guaranteed under the established sufficient conditions.

Download or read book Security and Resilience of Control Systems written by Hideaki Ishii and published by Springer Nature. This book was released on 2022-01-22 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises a set of chapters that introduce various topics pertinent to novel approaches towards enhancing cyber-physical measures for increased security and resilience levels in control systems. The unifying theme of these approaches lies in the utilization of knowledge and models of the physical systems, rather than an attempt to reinvigorate conventional IT-based security measures. The contributing authors present perspectives on network security, game theory, and control, as well as views on how these disciplines can be combined to design resilient, safe, and secure control systems. The book explores how attacks in different forms, such as false data injections and denial-of-service can be very harmful, and may not be detected unless the security measures exploit the physical models. Several applications are discussed, power systems being considered most thoroughly. Because of its interdisciplinary nature—techniques from systems control, game theory, signal processing and computer science all make contributions—Security and Resilience of Control Systems will be of interest to academics, practitioners and graduate students with a broad spectrum of interests.

This book was released on 2020 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cyber-physical system (CPS) is a mechanism that is controlled or monitored by computer-based algorithms. In cyber-physical systems, physical and software components are deeply intertwined, each operating on different spatial and temporal scales, exhibiting multiple and distinct behavioral modalities, and interacting with each other in many ways that change with context. Advances in CPS will enable capability, adaptability, scalability, resiliency, safety, security, and usability to expand the horizons of these critical systems. Examples of CPS include smart grid, autonomous automobile systems, medical monitoring, process control systems, robotics systems, and automatic pilot avionics. The lack of strong cyber-physical modeling capabilities presents many challenges across the design, development, verification, and maintenance phases of a system [29]. Novel techniques for modeling the cyber-physical components and analysis and verification techniques are imperative to deploy a resilient and robust system. In this work, two different cyber-physical systems, air traffic control system and power distribution control center, are modeled and their resiliency against cyberattacks is evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: A critical challenge in deep learning is the vulnerability of deep learning networks to security attacks from intelligent cyber adversaries. Even innocuous perturbations to the training data can be used to manipulate the behaviour of deep networks in unintended ways. In this book, we review the latest developments in adversarial attack technologies in computer vision; natural language processing; and cybersecurity with regard to multidimensional, textual and image data, sequence data, and temporal data. In turn, we assess the robustness properties of deep learning networks to produce a taxonomy of adversarial examples that characterises the security of learning systems using game theoretical adversarial deep learning algorithms. The state-of-the-art in adversarial perturbation-based privacy protection mechanisms is also reviewed. We propose new adversary types for game theoretical objectives in non-stationary computational learning environments. Proper quantification of the hypothesis set in the decision problems of our research leads to various functional problems, oracular problems, sampling tasks, and optimization problems. We also address the defence mechanisms currently available for deep learning models deployed in real-world environments. The learning theories used in these defence mechanisms concern data representations, feature manipulations, misclassifications costs, sensitivity landscapes, distributional robustness, and complexity classes of the adversarial deep learning algorithms and their applications. In closing, we propose future research directions in adversarial deep learning applications for resilient learning system design and review formalized learning assumptions concerning the attack surfaces and robustness characteristics of artificial intelligence applications so as to deconstruct the contemporary adversarial deep learning designs. Given its scope, the book will be of interest to Adversarial Machine Learning practitioners and Adversarial Artificial Intelligence researchers whose work involves the design and application of Adversarial Deep Learning.

This book was released on 2017-01-27 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-physical systems (CPS) are "engineered systems that are built from, and depend upon, the seamless integration of computational algorithms and physical components." CPS can be small and closed, such as an artificial pancreas, or very large, complex, and interconnected, such as a regional energy grid. CPS engineering focuses on managing inter- dependencies and impact of physical aspects on cyber aspects, and vice versa. With the development of low-cost sensing, powerful embedded system hardware, and widely deployed communication networks, the reliance on CPS for system functionality has dramatically increased. These technical developments in combination with the creation of a workforce skilled in engineering CPS will allow the deployment of increasingly capable, adaptable, and trustworthy systems. Engineers responsible for developing CPS but lacking the appropriate education or training may not fully understand at an appropriate depth, on the one hand, the technical issues associated with the CPS software and hardware or, on the other hand, techniques for physical system modeling, energy and power, actuation, signal processing, and control. In addition, these engineers may be designing and implementing life-critical systems without appropriate formal training in CPS methods needed for verification and to assure safety, reliability, and security. A workforce with the appropriate education, training, and skills will be better positioned to create and manage the next generation of CPS solutions. A 21st Century Cyber-Physical Systems Education examines the intellectual content of the emerging field of CPS and its implications for engineering and computer science education. This report is intended to inform those who might support efforts to develop curricula and materials; faculty and university administrators; industries with needs for CPS workers; and current and potential students about intellectual foundations, workforce requirements, employment opportunities, and curricular needs.
