This paper presents the MILS Network Reference Architecture, including the added benefit of safety critical domains for a completely integrated mixed security and mixed safety hardware and software reference architecture for platforms, driving to minimal SWaP and maximum flexibility in the use of vehicles. Included are specific examples of techniques, application to specific systems, and performance concerns. Overall SWaP-C metrics are discussed. In addition, the enabled operational capability of user-based role and security level reconfiguration is explained in detail.
