Patent ID: 7716494

Claim:
A method for indicating the integrity of a processing system, the method comprising determining a configuration file including a list of one or more modules, the configuration file including one or more configuration file values associated with the one or more modules; measuring a characteristic of an operating system kernel; verifying the operating system kernel by comparing the measured characteristic of the operating system kernel to a predetermined value; when the operating system kernel is verified, then performing the steps of: extending the one or more configuration file values associated with the one or more modules into one or more platform configuration registers before executing of the operating system kernel; loading and executing the operating system kernel; loading the one or more configuration file values associated with the one or more modules from the configuration file; determining a configuration file value from the configuration file indicating a measure of a module to be loaded and executed; measuring a characteristic of a module to be loaded; determining, by a computer processor, when the measured characteristic matches the determined configuration file value from the configuration file; when the measure characteristic matches the determined configuration, performing, by the computer processor, the step of loading and executing the module; and when the measured characteristic does not match the determined configuration, changing, by the computer processor, the configuration value extended in the one or more platform configuration registers.
