摘要: The present invention relates to a data-processing device, particularly a chip card or smart card, and to a method of operating said device, with an integrated circuit comprising a central processing unit (CPU) (10) and one or more co-processors (12). The integrated circuit comprises a control unit (18, 30) which controls the processors, CPU (10) and co-processors (12) in such a way that, in the case of a cryptographic operation, at least two processors perform a cryptographic operation simultaneously and in parallel.

摘要: In a system having a mobile part and an immobile part between which data and energy are transmitted, an electronic control for two resonant circuits serve the purpose of transmitting energy to the mobile part. The resonant circuits are driven so that their oscillations have a prescribed phase shift relative to one another. For data transmission to the mobile part, a phase shift is superimposed on the transmitted signal at one resonant circuit. On the basis of the phase relation of the signals relative to one another, the mobile part can identify which resonant circuit is transmitting the data. The oscillation of the resonant circuit that is transmitting new data via the phase shift is used for the formation of the clock signal on the part of the mobile part.
