Secure Composable Operating System

What we do

We build a secure operating system based on a microkernel architecture to reduce complexity and maximize component isolation. Our system is composed of small building blocks that cooperate securely in a distributed use case. We co-design our operating system with the MPSoC and Wireless Connectivity groups to solve platform and network security problems. The Composable Operating Systems group will provide the essential building blocks from which customized systems for IoT use cases can be built.
