Industry 4.0 will only become a reality through the convergence of Operational and Information Technologies (OT & IT), which use different computation and communication technologies. Cloud Computing cannot be used for OT involving industrial applications, since it cannot guar-antee stringent non-functional requirements, e.g., dependability, trustwo...

Virtualization of distributed real-time systems enables the consolidation of mixed-criticality functions on a shared hardware platform, easing system integration. Time-triggered communication and computation can act as an enabler of safe hard real-time systems. A time-triggered hypervisor that activates virtual CPUs according to a global schedule c...

The GNU/Linux operating system (OS) is becoming more commonly used in real-time systems and has been modified with specific updates to provide faster and bounded response times as well as with fixed- and dynamic-priority real-time scheduling mechanisms. While the EDF-based scheduler ensures deadlines and temporal isolation for real-time tasks, it m...

In most distributed safety-critical applications, real-time tasks executing on multi-core multi-SoC platforms communicate critical messages over a deterministic communication backbone. Virtualization is increasingly used in such systems to enhance scalability and enforce spatial isolation while still maintaining the timing properties of critical ta...

Cyber-physical systems like cars, mobile agriculture machines, or duty vehicles are increasingly connected to public networks. Thus, in addition to their inherent fault-tolerance requirements, there is a pressing need to design these systems cost-effectively to withstand cyber-attacks, i.e., to ensure cyber resiliency. This paper implements a cyber...

Mixed-criticality is a key characteristic of Fog Computing Platforms posing challenging requirements concerning workload isolation, resource utilization, orchestration, and timing behavior. Virtualization featuring a hypervisor that logically partitions physical resources of edge computing devices has been identified to support these stringent requ...
