Arm TrustZone brings lightweight compartmentalisation to the M-Profile with Armv8-M security extensions. Compartmentalisation is a technique that separates code from important data or permissions, improving security by limiting the capabilities of risky…
For a beginner new to Arm-based microcontrollers, it can sometimes be a little difficult knowing where exactly to start finding all the useful information that will help with a new design. There are many resources available…
The Smart Home market is now at an inflection point. Early devices in the market were connected to the internet but were typically single-function, often lacking connectivity to other devices and with closed APIs, denying the user the ability to design…
2016's DDoS attacks on webcams revealed just how vulnerable IoT devices are to remote attacks. The embedded security community and device makers are well aware of these shortcomings but with cost being a primary driver, security implementation often…
Arm TrustZone technology is a system-wide approach to security for system-on-chip (SoC) designs. It is hardware-based security built into the heart of CPUs and systems and used by semiconductor chip designers who want to provide security to devices, such…
ARM recently announced the first two processors using the ARMv8-M architecture, ARM Cortex-M23 and Cortex-M33. ARM TrustZone for ARMv8-M adds security features to these cores that allow applications and services to operate securely while safeguarding…
