Dieses Buch bietet eine grundlegende Untersuchung der Informationssicherheit durch die Linse der Kryptographie, die von klassischen zu modernen Systemen �bergeht. Zu Beginn wird die Verschl�sselung mit symmetrischen Schl�sseln anhand der Hill-Chiffre veranschaulicht, die Daten mithilfe der linearen Algebra umwandelt, und es wird das Konzept der perfekten Geheimhaltung mit dem One-Time-Pad vorgestellt, wobei dessen praktische Grenzen bei der Schl�sselverwaltung aufgezeigt werden. Der Hauptteil des Textes befasst sich dann mit der Kryptographie mit �ffentlichen Schl�sseln, am Beispiel von RSA, das das Problem der Schl�sselverteilung durch mathematisch verkn�pfte �ffentliche und private Schl�ssel l�st. Durch die Beispiele hindurch betont das Buch wichtige praktische Lektionen: die Notwendigkeit, ausreichend gro e Schl�ssel zu verwenden, die Wichtigkeit einer angemessenen Verschl�sselung und Auff�llung und die Tatsache, dass Sicherheit nicht nur von starken Algorithmen abh�ngt, sondern auch von einer robusten Implementierung und dem Schutz der Schl�ssel. Letztlich wird die Informationssicherheit als eine dynamische, vielschichtige Disziplin dargestellt, die eine st�ndige Anpassung erfordert, um Vertraulichkeit, Integrit�t und Verf�gbarkeit gegen die sich entwickelnden Bedrohungen abzuw�gen.
