method for increasing the safety of circuits against unauthorized access

摘要

Method for increasing the security of circuits, especially smart card circuits, against unauthorized access in which the signal curves produced by data processing processes in self-timed circuits are decoupled. ??An Independent claim is made for an arrangement for increasing the security of circuits, especially smart card circuits, against unauthorized access in which an adjustable device (2) for power regulation is connected between the power supply (3) and the self-timing circuit (1).
