Abstract

The invention is characterized in that the data processing unit detects the error and then sends a first coded message to a central data processing facility. The central data processing facility decodes the signal and evaluates information on the error contained in the first message. Depending on the result of said evaluation, the central data processing facility then generates and/or selects an error elimination routine. The central data processing facility issues a program instruction that can be executed by the data processing unit. The program instruction is then coded by the data processing facility and sent to the data processing element as part of a second message.

Claims

1. A method for correcting an error that occurs in a data processing unit, whereby the data processing unit detects the error and subsequently transmits a message to a central data processing system, whereby the central data processing system evaluates the information about the error, whereby information is exchanged in encrypted form between the central data processing system and the data processing unit, characterized in that the central data processing system decrypts the signal, in that the central data processing system evaluates the information about the error contained in the first message and, depending on the result of this evaluation, generates and/or selects an error correction routine, and in that the central data processing system issues a program instruction that can be executed by the data processing unit and transmits it in encrypted form to the data processing unit.

2. The method according to claim 1, characterized in that, by examining the second message, the data processing unit verifies whether this message comes from the central data processing system.

3. The method according to one or both of claims 1 or 2, characterized in that the data processing unit receives the encrypted second message and executes the program instruction contained therein.
