Abstract
A method of protecting a microcomputer system against manipulation of its program, in which the microcomputer system includes a rewritable memory in which at least one portion of the program is stored, and in which a check is performed as part of a checking procedure to determine whether at least one portion of the rewritable memory includes a specified content. To permit detection of a manipulated program in the shortest amount of time, the checking procedure is executed cyclically at preselectable intervals during operation of the microcomputer system. In addition, execution of the program is blocked immediately as part of the checking procedure if the rewritable memory or a portion thereof does not include the specified content.
