About the Book

Kryptografie ist ein wichtiges Mittel um IT-Systeme zu schützen. Sie ermöglicht nicht nur die Verschlüsselung von Nachrichten, sondern auch digitale Unterschriften, die Authentifizierung und die Anonymisierung von Kommunikationspartnern. Das hier vorliegende Buch ist eine Einführung in die Kryptografie für Studierende ? von der symmetrischen über die asymmetrische Verschlüsselung bis hin zu Hash-Funktionen. Mit Übungsaufgaben und Lösungen können Sie Ihr frisch erworbenes Wissen überprüfen und festigen. So ist dieses Buch umfassend, keinesfalls oberflächlich, aber ohne Vorwissen verständlich.
