Goal

Cryptography is nowadays daily used, e.g., for ensuring secure Internet communication. Particularly important are encryption schemes that aim to provide confidentiality of data. Over the last decades, cryptographers developed several schemes that are in practical use everywhere. As major goal is to provide security, it is necessary to understand how the security of such schemes is evaluated. In fact, the evaluation of cryptographic schemes represents an own research field, termed "cryptanalysis". 

Consequently, a comprehensive education of cryptography is only possible if at least the most important cryptanalysis techniques are taught as well. Unfortunately, often these techniques are not easy to understand. The goal of this teamproject is to develop measures that support the teaching of the most important cryptographic attacks. To this end, the project will be a collaboration with the team of the open source software "CrypTool 2" (CT2). CT2 allows to visualize cryptographic algorithms and is a popular tool in education. For example, it is regularly used in the lectures on cryptography given here at the University of Mannheim. 

While CT2 provides a variety of algorithms already, there is a lack of modules that visualize attacks. The aim of this project is to close this gap.
