Verifying the integrity of a computing platform

1. A method to verify integrity of a target instance of a computing platform, the method comprising:

executing a 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; and

comparing the first set of execution parameter values with a second set of execution parameter values included in the software image, wherein the second set of execution parameter values is associated with executing the portion of the software image at a secure instance of the computing platform.

2. The method of claim 1 , wherein the set of operations further comprises:

determining a verification message based on said comparing the first set of execution parameter values with the second set of execution parameter values; and

sending the verification message to a secure computing platform.

3. The method of claim 2 , wherein the set of operations further comprises:

receiving instructions from the secure computing platform in response to the verification message; and

performing an action at the target instance of the computing platform based on the received instructions.

4. The method of claim 3 , wherein the action is resetting the target instance of the computing platform to a secure state.

5. The method of claim 3 , wherein the action is activating software code that was embedded in the software image.

6. The method of claim 1 , wherein at least one execution parameter is one of: total cycles, absolute starting time, absolute ending time, Global Positioning System (GPS) parameters, or a number of instructions that were executed.

7. A non-transitory computer-readable storage medium storing a software image that, when executed by a target instance of a computing platform, causes the target instance of the computing platform to perform a method to verify integrity of the target instance of the computing platform, the method 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; and

comparing the first set of execution parameter values with a second set of execution parameter values included in the software image, wherein the second set of execution parameter values is associated with executing the portion of the software image at a secure instance of the computing platform.

8. The non-transitory computer-readable storage medium of claim 7 , wherein the method further comprises:

determining a verification message based on said comparing the first set of execution parameter values with the second set of execution parameter values; and

sending the verification message to a secure computing platform.

9. The non-transitory computer-readable storage medium of claim 8 , wherein the method further comprises:

receiving instructions from the secure computing platform in response to the verification message; and

performing an action at the target instance of the computing platform based on the received instructions.

10. The non-transitory computer-readable storage medium of claim 9 , wherein the action is resetting the target instance of the computing platform to a secure state.

11. The non-transitory computer-readable storage medium of claim 9 , wherein the action is activating software code that was embedded in the software image.

12. The non-transitory computer-readable storage medium of claim 7 , wherein at least one execution parameter is one of: total cycles, absolute starting time, absolute ending time, Global Positioning System (GPS) parameters, or a number of instructions that were executed.

13. A target instance of a computing platform, comprising:

a processor; and

a non-transitory computer-readable storage medium storing a software image that, when executed by the processor, causes the target instance of the computing platform to perform a method to verify integrity of the target instance of the computing platform, the method 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; and

comparing the first set of execution parameter values with a second set of execution parameter values included in the software image, wherein the second set of execution parameter values is associated with executing the portion of the software image at a secure instance of the computing platform.

14. The target instance of the computing platform of claim 13 , wherein the method further comprises:

determining a verification message based on said comparing the first set of execution parameter values with the second set of execution parameter values; and

sending the verification message to a secure computing platform.

15. The target instance of the computing platform of claim 14 , wherein the method further comprises:

receiving instructions from the secure computing platform in response to the verification message; and

performing an action at the target instance of the computing platform based on the received instructions.

16. The target instance of the computing platform of claim 15 , wherein the action is resetting the target instance of the computing platform to a secure state.

17. The target instance of the computing platform of claim 15 , wherein the action is activating software code that was embedded in the software image.

18. The target instance of the computing platform of claim 13 , wherein at least one execution parameter is one of: total cycles, absolute starting time, absolute ending time, Global Positioning System (GPS) parameters, or a number of instructions that were executed.
