Abstract

Zum sicheren Laden von Nutzdaten auf einen Datenträger (10) wird zunächst eine Blinddateneinheit bereitgestellt (14), die eine Zufallszahl sein kann. Ferner wird eine Nutzdateneinheit bereitgestellt (14), die aus einer Folge von Nutzdateneinheiten stammt und Nutzinformationen darstellt. Um eine Leistungsanalyse zum Ermitteln des Hamming-Gewichts von verarbeiteten Nutzdaten abzuwehren, wird vor dem Laden einer Nutzdateneinheit auf den Datenträger (10), der z. B. ein Register oder ein Bus ist, zunächst eine Blinddateneinheit geladen. Damit kann ein Angreifer lediglich das Hamming-Gewicht aus einer Kombination von Nutzdateneinheit und Blinddateneinheit ermitteln, jedoch nicht das Hamming-Gewicht der Nutzdateneinheit selbst.
