Abstract: The invention relates to a method for protecting at least one motor vehicle component against manipulation in a control device, which comprises at least one microcomputer (?C) and at least one memory module (2, 3), characterized in that the microcomputer (?C) reads out a specific original identifier (ID) of at least one memory module (2, 3) from the memory module (2, 3) and stores it. Furthermore the invention relates to a control device for a motor vehicle component which comprises at least one microcomputer (?C) and at least one memory module (2, 3), characterized in that at least one memory module (2, 3) has at least one specific identifier (ID) and the microcomputer (?C) has at least one area (11) in which at least one specific original identifier is stored.

Abstract: The invention relates to a method for protecting at least one motor vehicle component against manipulation in a control device, which comprises at least one microcomputer (?C) and at least one memory module (2, 3), characterized in that the code which is necessary for operation of the control device (1) is divided into at least one master code (MC) which comprises information essential for operation of the control device (1), and at least one sub-code (SC) which comprises additional information for operation of the control device (1), at least the master code (1) being stored in the microcomputer (?C) and the master code (MC) monitoring the manipulation of the sub-code (SC).

Abstract: The invention relates to a method for protecting against manipulation of a controller for at least one motor vehicle component, the control device (1) comprising at least one microcomputer (?C) and at least one memory module (2, 3), at least one of the memory modules (2, 3) constituting a reversible read-only memory (3), characterized in that the reversible read-only memory (3) stores data which have been encrypted by an encryption process, and the key used in the encryption process comprises at least one part of at least one original identifier (ID) of at least one of the modules (?C, 2, 3) of the control device, which identifier is specific to the module.

Abstract: The invention relates to a method for protecting at least one motor vehicle component against manipulations in a control device, comprising at least one micro-computer (?C) and at least one memory component (2, 3). The invention is characterized in that the micro-computer (?C) reads and memorizes a specific, original identification (ID) of at least one component (2, 3) of a memory component (2, 3). The invention also relates to a control device for a motor vehicle component comprising at least one micro-computer (?C) and at least one memory component (2, 3). The invention is characterized in that the at least one memory component (2, 3) comprises at least one specific identification (ID) and the micro-computer (?C) comprises at least one area (11) wherein the at least one specific original identification is stored.
