    摘要： The contents of a ROM are highly reliably changed while the ROM is attached to a substrate. A vehicle control device has an electrically programmable nonvolatile memory storing a vehicle control program. A ROM update process includes a collation in which a check is made to determine whether the updating of the ROM was correctly executed. An abnormal process ensures an output from the control device clearly is an abnormal control amount under even ordinary vehicle drive conditions.

    摘要： A centralized controller 2 controls facility equipment 3a and 3b according to a sequence control program corresponding to standard functions of the facility equipment 3a and 3b. In addition, the centralized controller 2 receives control information for controlling a unique function of the facility equipment 3a and 3b and a PIN code, which are transmitted from a programmable controller 1, and transmits, if the PIN code is a valid code, the control information to the facility equipment 3a and 3b.

    摘要： An ECU includes a microcomputer that has an integrated flash memory. An initial writing flag is set in the microcomputer before an initial writing to the flash memory. The microcomputer enters into a writing mode when the flag determines permission of data writing. When the data-writing to the flash memory is completed, the flag is cleared.

    摘要： A system and method for changing safety-relevant data for a control device is provided wherein an authorized user inputs new or altered safety-relevant data, which is received on a data processing installation. A first checksum for the safety-relevant data is established and stored along with the safety-relevant data in at least one data record on the data processing installation. An enable code may also be stored in the at least one data record. This enable code may be produced by a code generator and encrypted by a key module. The data processing installation then reads back the safety-relevant data from a memory in the data processing installation, thereby allowing a comparison of the received safety-relevant data and the read back safety-relevant data. A second checksum is generated in a case where the comparison resulted in no differences. The second checksum may also be stored in the at least one data record. At least one new data record containing the safety-relevant data, the encrypted enable code and the first and second checksums is created and transmitted to the control device. The new data record is checked against prior data records and prior checksums stored on a storage medium to determine that the at least one new data record is known to the control device.

    摘要： Exemplary embodiments are directed to a system and method of checking, during regular operation of a Process Control PC or Substation Automation SA system, an intended configuration modification for a mission-critical IED. The IED receives, from an authenticated requestor, a modification request directed to IED configuration, parameter or setting data. The IED then checks the requested configuration modification, and rejects it in case no approval or confirmation is made by an approver independent of the requestor, and otherwise accepts and implements. The IED authenticates the approver prior to receiving the request, and stores, in a local memory, a configuration modification plausibility check provided by the approver. The stored plausibility check is then performed, by a plausibility checking unit, on the intended modification, and the latter is rejected or approved based on a result of the stored plausibility check when applied to specific circumstances of the configuration modification request.

    摘要： A data-processing system having at least one operating memory holding operating data is provided with a protection unit having an execution environment protected from unauthorized access. At least one monitoring logic in the execution environment is connected to the operating memory for monitoring unauthorized modifications, access, or similar protection violations of the operating data stored in the operating memory and for generating an output on detection of such a protection violation. A protection logic in the execution environment holds replacement data capable of replacing the operating data and is connected to the monitoring logic for, on generation of the output, providing to the operating memory the replacement data for the operation or for a substitute operation of the data-processing system.

    摘要： In a process for ensuring the data integrity of software for influencing operation of a control unit of a motor vehicle, a pair of keys is provided for encrypting and decrypting electronic data. The first key is stored for access by a control unit in the motor vehicle, and software which is to be imported is signed by means of the second key. The signed software is imported into the memory of the control unit and the signature of the software is checked by means of the first key. The signature is accepted if the check has a positive result.
