Flat but trustworthy:security aspects in flattened hierarchical scheduling

Abstract	Virtualization is a well-proven technology for consolidating desktop and server applications onto the same hardware platform while maintaining their native environments. However, although embedded real-time systems start to adopt this technology, constrained resources and strict timelines demands complicate this consolidation task, in particular if some applications are more critical than others and if the timeliness of the latter may be sacrificed for the sake of completing the former. In a previous publication, we have introduced flattening as a means to integrate mixed-criticality tasks into a single real-time system while maintaining most of their native environment as it is provided by virtual machines (VMs) and their monitors. In this paper, we focus on the security and trustworthiness aspects of flattening and on the interfaces for isolating mixed-criticality VMs on top of our microkernel for embedded real-time systems.
