Existing industry open standards for Integrated Modular Avionics (IMA) such as ARINC 653 are quite limited in scope when considering the IMA platform as a whole. Open standards bring many benefits to the IMA platform, as they enforce commonality, enable portability, promote re-use, and harness industry-wide best practices, just to name a few. At present, there exists an opportunity to advance the use of open standards in IMA systems, thereby extending the aforementioned benefits to all stakeholders in the industry.

Systems deploying Integrated Modular Avionics (IMA) architectures have enabled manufacturers to reduce aircraft weight and form common computing platforms; consequently, the demand for such systems has been increasing in both military and commercial aircraft. The benefits of IMA architectures are primarily fulfilled by a consolidation of multiple standalone ("federated") systems into a single Systems-of-Systems (SoS) deployment. Contemporaneous to the increase in demand for IMA systems in the military and commercial aviation fields is the increasing amount of security required in airborne systems 1 . As the demand for IMA systems converges with the demand for secure systems, the need for composition of Information Assurance (IA) properties in such a SoS emerges.
