Introduction to Modern Cryptography SoSe2023

In the past, cryptography was considered a tool for intelligence agencies and diplomats. Those times also lead to the development of the well-known Enigma encryption machine.
But today, cryptography is a key technology for secure communications and the secure usage of digital media. Barely noticed by the public, cryptography has become widely used in everyday devices such as ATMs and mobile phones.

The design of cryptographic components is difficult, and in practice, one often encounters terrible design errors. (The IT security expert Bruce Schneier commented it drastically: "Billions of dollars are spent on computer security, and most of it is wasted on unsafe products.") But even more difficult is the correct usage of "good" components. Hence, cryptography requires a thorough understanding of the particular conditions under which a component can be considered "secure".

The lecture introduces the way of thinking and the methodology of IT security and modern cryptography. The goal is to understand why certain systems can be considered secure, why others are considered insecure, and how to employ cryptographic techniques to solve problems in IT security.
