Beschreibung der Lehrveranstaltung
Security and Cryptography I
Deutsch
Goals: -
This module gives a thorough introduction to security in general and to multilateral security of
IT-systems in particular. Protection goals and their interdependencies are discussed as well as
reasonable attacker models. Different kinds of security mechanisms are introduced to provide examples
and to clarify that security mechanisms are means to provide for protection goals against attackers at
most as powerful as described in the attacker model.
Cryptosystems are the fundamental security mechanisms to achieve the protection goals confidentiality
and integrity in distributed IT-systems and are therefore discussed in depth: We start by a classification
of cryptosystems according to the protection goal they are aiming at and the key-distribution they use.
We concentrate on those cryptosystems, whose security is as much validated as possible or even provable.
We stress the kind of validation or proof.
Participants are enabled both to define and analyze security properties of IT-systems in two respects:
What security properties the IT-system is supposed to have and how sure we can be that it really has
these properties with respect to could be attackers. In addition, basic knowledge is acquired and basic
skills are developed how to construct secure IT-systems.
Kinds of teaching: - Lecture and exercises integrated dynamically into each other each filling out
approximately half of every teaching event. In the exercises not only the contents of the lectures
are applied and practiced, but new knowledge discovered by yourself.
