Composable Mission-Critical Embedded System Architecture for High Assurance

Mission-critical systems must go through a laborious and lengthy high assurance certification process. Slight modifications of a certified system often trigger a new certification cycle. We have leveraged a Modular Open Systems Approach (MOSA) and developed a composable Embedded-Security-as-a-Service (ESaaS) architecture for mission-critical embedded systems. A zero-trust approach has been applied to incorporate security and resilience technologies and address mission assurance requirements. In this paper, we discuss an ecosystem that supports the acquisition and certification processes of high assurance ESaaS modular embedded systems for critical missions.
