Establishing secure initial state in a processing platform containing both high assurance security and safety-critical functions

摘要

A method including initializing the processing platform, wherein initializing the processing platform includes performing a power on self-test (POST) configured to determine an operational state of one or more hardware sub-components of the processing platform, the POST further configured to determine an error detection state of one or more monitoring functions of the processing platform, initializing a safety monitoring function of the processing platform, analyzing one or more results of the POST utilizing the safety monitoring function of the processing platform in order to determine compliance of the processing platform with operational requirements, configuring the safety monitoring function of the processing platform utilizing one or more sets of safety monitoring configuration data, initializing and configuring a security monitoring function of the processing platform, and initializing and configuring one or more security functions.
