This paper provides an overview of some principles and mechanisms to securely operate mixed-criticality real-time systems on embedded platforms. Those principles are illustrated with PharOS a complete set of tools to design, implement and execute real-time systems on automotive embedded platforms. The keystone of this approach is a dynamic time-triggered methodology that supports full temporal isolation...
This paper presents a low-level memory and hardware model suitable for analyzing embedded systems software written in high-level languages such as C. The key feature of this approach is that it combines information that can be discovered from the C code itself with information from the executable binary program. Further, it also integrates effects caused through hardware dependencies. We describe...
In this paper we are interested in mixed-criticality embedded real-time applications mapped on distributed heterogeneous architectures. The architecture provides both spatial and temporal partitioning, thus enforcing enough separation for the critical applications. With temporal partitioning, each application is allowed to run only within predefined time slots, allocated on each processor. The sequence...
As newer software engineering technologies, such as Service-Oriented Architecture (SOA), become the basis for mission-critical systems, they must include security as a foundational capability. This paper highlights security concepts relevant to using SOA as a foundation for a Common Operating Environment (COE), i.e., a set of infrastructure and common services for developing and executing applications...
