description A system, method, and apparatus are provided for securely controlling operations of a data processing system by activating a security subsystem to control startup behavior of application subsystems, installing SMR parameters which include an initial authenticity proof for use with an initial verification process for the SMR and calculating an alternate authenticity proof for use with a subsequent verification process for the SMR, and then by subsequently verifying the SMR using the alternate authenticity proof for the subsequent verification process applied to the SMR so that the security subsystem can apply a comprehensive system reaction for the application subsystem based on the SMR verification results.
