Introduction
We understand the complexity of code and policy as the most fundamental security problem shared by modern general-purpose operating systems. Because of high functional demands and dynamic workloads, however, this complexity cannot be avoided. But it can be organized. Genode is a novel OS architecture that is able to master complexity by applying a strict organizational structure to all software components including device drivers, system services, and applications. The Genode OS framework is the effort to advance the Genode OS architecture as a community-driven Open-Source project.

The Genode release 9.11 introduces a paravirtualized Linux Kernel. The screenshot displays two Linux instances running on top of Genode - one Tinycore and one Busybox.
The Genode release 9.02 introduced support for native Qt4 applications. The screenshot displays the Tetrix Qt4 example application side-by-side with low-complexity graphical Genode applications.
The demonstration scenario provided with the official Genode distribution shows off Genode's ability to create and destroy arbitrarily shaped process trees, which can include multiple instances of services in a nested fashion. The screenshot shows an isolated instance of the GUI server running in a window of another GUI-server instance. The whole demo scenario including the graphical user interface has a source-code complexity of less than 20,000 lines of code. With Genode, graphically rich applications and a low-complexity trusted computing base are no contradiction.
