Data processing device e.g. smart card, error detection functionality checking device, has error detection device, computing device or input data, which are so influenced that alarm signal is delivered, if no error signal is received

摘要

The device has a computing device for providing an output data based on the input data. An error detection device detects an error based on the output data, during correct execution of the error detection functionality. The error detection device, the computing device or the input data are so influenced that an alarm signal, which indicates an incorrect execution of the error signal functionality, is delivered, if no error signal is received. Independent claims are also included for the following: (1) a method for checking an error detection functionality of a data processing device (2) a program with a program code for implementing the method for checking an error detection functionality of a data processing device.
