A communications, navigation and identification (CNI) avionics system is disclosed. The CNI system includes a first integrated sensor performing a first CNI function and a second integrated sensor performing a second CNI function of a lower priority than the first CNI function. A first communication path is assigned to the first integrated sensor such that it carries signals between the first integrated sensor and a first system asset. A second communication path is assigned to the second integrated sensor such that it carries signals between the second integrated sensor and a second system asset. Each of the first and second communication paths includes a common first interconnect coupled to both of the first and second integrated sensors, a common second interconnect coupled to each of the first and second system assets, and a separate cryptographic processor. A resource management controller reassigns the second communication path to the first integrated sensor in the event of a failure of the first communication path so that the higher priority CNI function is maintained.
