This seminar provides an in-depth coverage of Information Security and Cryptography from both a conceptual and an application-oriented viewpoint. At the same time, the mathematical, algorithmic, protocol-specific, and system-oriented aspects are explained in a way understandable to a wide audience. This includes the foundations needed to understand the different approaches, a critical look at the state-of-the-art, and a perspective on future security technologies.

The material is presented at three different levels. At the highest level, the basic concepts are presented in detail, but abstractly (e.g., as black boxes), without mathematics. No background is required to follow at this level. At an intermediate level, the most important concrete schemes, models, algorithms, and protocols are presented as well as their applications. Here some minimal mathematical and systems background is assumed. At the deepest level, which is not required to understand the higher levels, different special topics, requiring some mathematical background, are discussed.
