  2. 1. Event Prediction and Bootstrap in Time Series

    Author : Anders Svensson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; bootstrap control.; statistical bootstrap; catastrophe; level-crossings; ARMAX process; Optimal alarm system; time series; optimal event predictor; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. READ MORE

  4. 2. Defense of Cyber-Physical Systems Against Learning-based Attackers

    Author : Rijad Alisic; Henrik Sandberg; Karl H. Johansson; Miroslav Pajic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Theory; Security; Privacy; Machine Learning; Cyber-Physical Systems; Change Point Problems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Cyberattacks against critical infrastructures pose a serious threat to society, as they can have devastating consequences on the economy, security, or public health. These infrastructures rely on a large network of cyber components, such as sensors, controllers, computers, and communication devices, to monitor and control their physical processes. READ MORE

  5. 3. Stealthy Sensor Attacks on Feedback Systems : Attack Analysis and Detector-based Defense Mechanisms

    Author : David Umsonst; Henrik Sandberg; Hideaki Ishii; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis, we investigate sensor attacks on feedback systems and how anomaly detectors can be used as a defense mechanism. We consider an attacker with access to all sensor measurements and full knowledge about the closed-loop system model. READ MORE
