Abstract
An electronic data processing circuit includes an operating module such as a microprocessor, at least one data memory and a data bus extending between the data memory and the operating module. In order to provide an electronic data processing circuit which is better protected against undesired alterations, at least one encoding module is provided in the region between the data memory and the data bus and/or in the region between the operating module and the data bus. The encoding module is constructed in such a way that data traffic between the operating module and the data bus or between the data memory and the data bus can be encoded and/or decoded.
