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 (&#x3bc;C) and at least one memory module (), characterized in that the microcomputer (&#x3bc;C) reads out a specific original identifier (ID) of at least one memory module () from the memory module () and stores it. Furthermore the invention relates to a control device for a motor vehicle component which comprises at least one microcomputer (&#x3bc;C) and at least one memory module (), characterized in that at least one memory module () has at least one specific identifier (ID) and the microcomputer (&#x3bc;C) has at least one area () in which at least one specific original identifier is stored.

Motor vehicle control device

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 (&#x3bc;C) and at least one memory module (), characterized in that the code which is necessary for operation of the control device () is divided into at least one master code (MC) which comprises information essential for operation of the control device (), and at least one sub-code (SC) which comprises additional information for operation of the control device (), at least the master code () being stored in the microcomputer (&#x3bc;C) and the master code (MC) monitoring the manipulation of the sub-code (SC). The invention furthermore relates to a control device for a motor vehicle component which comprises at least one microcomputer (&#x3bc;C) and at least one memory module (), the code which is necessary for operation of the control device () being divided into at least one master code (MC) which comprises information which is essential for operation of the control device (), and at least one sub-code (SC) which comprises additional information for operation of the control device (), and at least the master code (MC) being stored in the microcomputer (&#x3bc;C) and the master code (MC) containing a software function module for detection of manipulation within the sub-code (SC).

Method for protecting a motor vehicle component against manipulations in a control device and control device

A method of protecting a microcomputer system against manipulation of data stored in a memory assembly of the microcomputer system is provided. The method may protect, for example, a control program stored in the memory assembly of a motor vehicle control device. To secure and reliably protect the microcomputer system against manipulation of the data, the data is stored in the memory assembly marked or encrypted using an asymmetrical encryption method. The data may, for example, be encrypted outside the microcomputer system using an encryption algorithm and a private key, which is accessible to only a limited group of persons. The data may be decrypted in the microcomputer system using a decryption algorithm and a freely accessible public key.

Method of protecting microcomputer system against manipulation of data stored in a memory assembly of the microcomputer system

The invention relates to a method for protecting against manipulation of a controller for at least one motor vehicle component, the control device () comprising at least one microcomputer (&#x3bc;C) and at least one memory module (), at least one of the memory modules () constituting a reversible read-only memory (), characterized in that the reversible read-only memory () 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 (&#x3bc;C,) of the control device, which identifier is specific to the module.

Method for protecting against manipulation of a controller for at least one motor vehicle component and controller

A method of operating a microcomputer system in which at least part of a memory system of the microcomputer system is checked for manipulation of data stored in the memory system. Measures to prevent processing of the data in the microcomputer system are performed as a function of the result of the check, if the measures are activated. The measures are activated or deactivated as a function of the content of a read-only memory of the microcomputer system. To increase the effectiveness and reliability of a manipulation or tuning protection of the data, a code word is stored in the data, which is checked while the microcomputer system is in operation, and the measures are activated or deactivated as a function of the result of the check of the code word stored in the data.
