Method and system for reconciling safety-critical and high assurance security functional requirements between safety and security domains

Abstract

Systems and methods for providing safety and security functions are disclosed. The system includes a computing device that provides at least a first partition and a second partition. The computing device implements time and space partitioning to isolate resources available to the first partition and the second partition. The system also includes a safety module that operates in the first partition for providing safety functions for the system. The system further includes a security module that operates in the second partition for providing security functions for the system. A predefined communication interface is utilized to facilitate communications between the safety module and the security module. The communication interface defines a set of communications allowable between the safety module and the security module, wherein information sharing between the safety module and the security module is restricted to only the set of communications allowed through the communication interface.
