However, it will be recognized by one skilled in the art that the present invention may be practiced without these specific details or with equivalents thereof. Appropriate corrective action includes, but is not limited to, shutting down the computer and informing the user. In other words, any processor not executing the integrity check program is halted in a way that its future work is determined by the CPU/thread running the integrity check program. The method as in claim 1, wherein said pre-determined event comprises said execution of said integrity check program branching outside said integrity check program. The method as in claim 1, wherein said pre-determined event comprises an exception. For example, a malicious agent might subvert the O/S and set up a future DMA write to occur after the integrity check program has successfully executed.
) that is used to store an integrity or security bit 155. For example, the timer s period can be established only once per time the computer system is booted. Those events may include exceptions, interrupts, and write DMAs. If the checksum test fails, then the detection bit is set to a state such as, â€œunsuccessful completion. In step 340, the hardware resets the secure timer to start a new time interval if the detection bit indicates successful completion of the integrity check program upon exit. 5 illustrates circuitry of an exemplary computer system 100, which may form a platform for embodiments of the present invention.
However, the present invention is not limited to these events. It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. The events may include interrupts, exceptions, and DMA writes to certain memory locations.bobby valentino dating antoine dodson.
