1. A method to verify the integrity of a target instance of a computing platform, the method comprising: generating a software image that, when executed at the target instance of the computing platform, verifies integrity of the target instance of the computing platform based on comparing (1) a first set of execution parameter values measured during an execution of a portion of the software image at the target instance of the computing platform with (2) a second set of execution parameter values associated with executing the portion of the software image at a secure instance of the computing platform, wherein the first set of execution parameter values represents a first sequence of execution states that the target instance of the computing platform passes through while executing the portion of the software image, and wherein the second set of execution parameter values represents a second sequence of execution states that the secure instance of the computing platform is expected to pass through while executing the portion of the software image; sending the software image to the target instance of the computing platform; receiving a verification message from the target instance of the computing platform, wherein the verification message was generated by the software image while the software image was executing at the target instance of the computing platform; and verifying integrity of the target instance of the computing platform based on the verification message.
