Abstract

A method for processing an operating sequence of instructions of a program in a processor, wherein each instruction is represented by an assigned instruction code which comprises one execution step to be processed by the processor or a plurality of execution steps to be processed successively by the processor, includes determining an actual signature value assigned to a current execution step of the execution steps of the instruction code representing the instruction of the operating sequence; determining, in a manner dependent on an address value, a desired signature value assigned to the current execution step; and if the actual signature value does not correspond to the desired signature value, omitting at least one execution step directly available for execution and/or an execution step indirectly available for execution.
