Method, processor and device for checking the integrity of user data

Abstract

Provided is a method for checking the integrity of user data by a processor, which includes a method step for a first check value for the user data to be computed during a security-protected mode of operation. The method includes a further method step for the first check value to be stored in a security-protected memory module of the processor during the security protected mode of operation. The method includes a further method step for a second check value for the user data to be computed during a runtime mode. The method includes a further method step for the first check value to be compared with the second check value by the processor during the runtime mode. The method includes a further method step for a piece of control information to be provided by the processor during the runtime mode, wherein the control information includes a result of the comparing.

Dependencies are inferred from the claim text.
