- 7th International Conference on Education and Information Systems, Technologies and Applications (EISTA 2012), Reducing the complexity of understanding cryptology using CrypTool , July 2012
[Abstract - Cryptography and cryptanalysis are characterized by a great number of algorithms, parameters, and protocols where at least some of them can be considered as complex mathematical structures. In this paper, electronic learning such as self-regulated learning, computer-based trainings, and learning by doing are presented with the help of a modern e-learning program – CrypTool (CT) – which supports these approaches for developers and users. Additionally, this paper fortifies these claims with an evaluation using the feedback from classes where CT was used to teach cryptographic algorithms. EISTA 2012 was part of the 6th International Multi-Conference on Society, Cybernetics and Informatics (IMSCI 2012).]

- 15th Colloquium for infomation Systems Security Education Fairborn, Teaching Cryptology at All Levels Using CrypTool, June 2011
[Abstract - This paper introduces cryptology in the framework of general cybersecurity and advocates that it is an appropriate mechanism for introducing security issues into the classroom at all level of the curriculum. As practical free software package CrypTool can be a major asset in any attempt to teach cryptology to a range of student audiences is presented. Applications and classroom experiences using CrypTool are discussed along with some student feedback.]
