1. A method to verify the integrity of a target instance of a computing platform, the method comprising: receiving a software image at the target instance of the computing platform; and executing the software image at the target instance of the computing platform, thereby causing the target instance of the computing platform to verify the integrity of the target instance of the computing platform by performing a set of operations, comprising: measuring a first set of execution parameter values during an execution of a portion of the software image at the target 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 comparing the first set of execution parameter values with 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 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.
