A Secure Deterministic Fabric (SDF) switch architecture and design may provide a cost effective reconfigurable Multiple Single Levels (MSL) of Security implementation that is low risk to certify and may not require recertification after an initial certification evaluation. The SDF switch enables assignment of processing resources and attached payloads to a specific security level fabric for use by an operational system. The assignment of defined security levels is commanded by a SDF control and status module without changing certification, aircraft wiring, or revising hardware. The processing resources are statically assigned during power up on a per mission basis or dynamically reassigned between security levels during a mission as processing requirements may change as a result of mission stage. The SDF switch supports mission defined security configurations for individual security level operational payload processing.
