Hundreds of millions of mobile devices worldwide rely on Trusted Execution Environments
(TEEs) built with Arm TrustZone for the protection of security-critical applications (eg, DRM) …

Security is an increasing concern for real-time systems (RTS). Over the last decade or so,
researchers have demonstrated attacks and defenses aimed at such systems. In this article …

Embedded devices are becoming increasingly pervasive in safety-critical systems of the
emerging cyber-physical world. While trusted execution environments (TEEs), such as ARM …

Given the increasingly complex and mixed-criticality nature of modern embedded systems,
virtualization emerges as a natural solution to achieve strong spatial and temporal isolation …

In TrustZone-assisted TEEs, the trusted OS has unrestricted access to both secure and
normal world memory. Unfortunately, this architectural limitation has opened an aisle of …

Embedded systems comprise of low-power microcontrollers and constitute computing
systems from IoT nodes to supercomputers. Unfortunately, due to the low power constraint …

This article describes the first public implementation and evaluation of the latest version of
the RISC-V hypervisor extension (H-extension v0. 6.1) specification in a Rocket chip core …

As we connect more microcontrollers to the Internet and employ them to control the physical
world around us, their reliability and security are increasingly important. Many …

In the era of the Internet of Things (IoT), billions of wirelessly connected embedded devices
rapidly became part of our daily lives. As a key tool for each Internet-enabled object …

Security is one of the main challenges of the Internet of Things (IoT). IoT devices are mainly
powered by low-cost microcontrollers (MCUs) that typically lack basic hardware security …
