  1. 1. On Safe and Secure Communication in Process Automation

    Författare :Johan Åkerberg; Mats Björkman; Maria Lindén; Mikael Gidlund; Lutz Rauchhaupt; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : In the process industry, network and system security have become important since the introduction of Ethernet-based fieldbus protocols. As an example, a successful attack on a power plant, supporting large cities with energy, could result in a temporal but total power loss. Such attacks could be devastating for the society. LÄS MER

    Sammanfattning : This Licentiate thesis is about security in automation networks with emphasis on fieldbus communication. In the process industry, network and system security have become even more important since the introduction of Ethernet-based fieldbus protocols. LÄS MER

  4. 3. Virtualizing Operational Technology by Distributed Digital Twins

    Författare :Abdullah Aziz; Olov Schelén; Ulf Bodin; Jerker Delsing; Johan Åkerberg; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital Twin; Industrial Digitalization; OT Virtualization; Microservices; Cyberfysiska system; Cyber-Physical Systems;

    Sammanfattning : Industrial digitalization, stemming from the convergence of Information Technology (IT) and Operational Technology (OT), is a transformative force in modern industries. The Industrial Internet of Things (IIoT) and Industrial Cyber-Physical Systems (ICPS) empower industries with enhanced production processes, data-driven insights, and advanced automation. LÄS MER

  5. 4. Improving Development of Communication Software in Industrial Control Systems using Simulation

    Författare :Niclas Ericsson; Mats Björkman; Johan Åkerberg; Thomas Lennvall; Per Hurtig; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Sciences; Datavetenskap datalogi ;

    Sammanfattning : In the industrial domain customers expect a product longevity of 10-20 years, with high reliability and availability. Since industrial distributed control systems often are safety critical, aspects such as determinism, low latency and jitter are crucial. LÄS MER

  7. 5. Improving Clock Synchronization Performance in Industrial Networks

    Författare :Rahul Nandkumar Gore; Elena Lisova; Johan Åkerberg; Mats Björkman; Han Song; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clock synchronization; Industrial networks; Internet of things; Industry 4.0; Network Calculus; Computer Science; datavetenskap;

    Sammanfattning : The recent advances in cyber-physical systems and industrial internet-of-things (IIoT) have enabled the convergence of information technology (IT) and operational technology (OT) worlds of industrial automation systems achieving higher productivity, reliability, and revenues. The availability of business-critical and production-critical data on the converged network has enabled new and advanced network-centric applications that require time-constrained embedded devices to be connected to “the internet.
