Abstract

Vorliegende Erkenntnis ist, dass die in vielen Systemen bereits vorhandene Gruppierung der individuell adressierbaren Einheiten eines Speichers (12) zu Gruppen bzw. Seiten (12a) verwendet werden kann, um die Komplexität der adressabhängigen Schlüsselgenerierung bei nur geringfügiger Verringerung an der Sicherheit deutlich zu verkleinern, wenn zunächst ein Seitenvorschlüssel auf der Basis einer Seitenadresse (30a) berechnet (36) wird und dann auf der Basis des Seitenvorschlüssels und der Wortadresse (30b) erst der individuelle Schlüssel ermittelt wird. Hierdurch kann die adressabhängige Schlüsselgenerierung in einen kryptographisch anspruchsvollen relativ aufwendigen Prozess, der aber nur selten durchgeführt werden muss, nämlich die Seitenvorschlüsselberechnung (34), und in einen schnellen, nahezu aufwandslosen Schritt (36), der für jedes Wort bzw. jede individuell adressierbare Einheit (12b) ausgeführt werden muss, nämlich die Ermittlung des individuellen Schlüssels auf der Basis des Seitenvorschlüssels und der Wortadresse (30b), aufgespalten werden.
