Zephyr and cryptography (Valerio Setti, Baylibre)

Among the large variety of RTOS available in the market, Zephyr emerged in recent years thanks to the continuously increasing number of features and its open source approach. It’s not just an OS, but it’s a complete solution that includes everything you need for an embedded project. Apart from the kernel which is of course the core part, there’s a multitude of drivers, compilers, architectures and boards which are already supported and it’s easy to port it to new ones. But what makes it unique among competitors is the large variety of subsystems which are already included (such as networking, storage, graphics and, last but not least, cryptography!) so that you don’t need to rely on any 3rd party provider to get started. This talk will start from an overview of the Zephyr architecture showing similarities with the embedded Linux scenario. Then the focus will shift toward security aspects of this OS (Mbed TLS, TF-M, McuBoot) which are essential for a secure IOT device.
