VORRICHTUNG ZUM LIEFERN VON AUSGANGSDATEN ALS REAKTION AUF EINGANGSDATEN UND VERFAHREN ZUM ÜBERPRÜFEN DER AUTHENTIZITÄT UND VERFAHREN ZUM VERSCHLÜSSELTEN ÜBERTRAGEN VON INFORMATIONEN

摘要

In order to determine authenticity of the device on the basis of output data, the device (10) for supplying output data (12) in reaction to input data (14) comprises an electronic circuit (16) for executing an algorithm that generates output data (12) on the basis of input data (14) and a device (18) for detecting operational data that is influenced by an operation of the electronic circuit (16). The device (18) for detecting operational data is coupled to the electronic circuit (16) in such a way that operational data of the electronic circuit (16) is used by the algorithm in order to generate output data (12). Safety of the device disclosed in the invention is enhanced in that a potential counterfeiter will have to simulate both the functionality of the device and hardware features of said device such as power consumption or time response in order to simulate an authentic card.
