Abstract:
1. A system for providing both safety and security functions, the system comprising: a computing device providing at least a first partition and a second partition, the computing device implementing time and space partitioning to isolate resources available to the first partition and the second partition; a safety module operating in the first partition, the safety module providing safety functions for the system; a security module operating in the second partition, the security module providing security functions for the system; and a predefined communication interface defining 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 allowable through the predefined communication interface, wherein the security functions provided by the security module include detecting a security violation, and wherein the set of communications allowable between the safety module and the security module includes a corrective action request from the security module to the safety module specifying a set of security-relevant partitions to be shutdown and restarted when the security violation is detected.
