- Jamie Kendall (University of Portsmouth): "Cryptographic Techniques for Network Security using CrypTool", April 2008, 91 pages
This project educates students in the basics of the field of classic and modern cryptography and the according cryptanalysis. The project explores the software CrypTool 1 extensively and comprises of a set of three one hour lab sheets as well as an accompanying report with the solutions.
- CrypTool 2 at CeBIT 2010
The University of Duisburg-Essen presented CrypTool 2 as e-learning platform, peers@play and the combination of both for distributed modern cryptanalysis.
- 15th Colloquium for infomation Systems Security Education Fairborn, Rong Yang, Layne Wallace, and Ian Burchett: "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. A practical free software package called CrypTool which 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.]
- 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).]
- Sasa Adamovic, Marko Sarac, Mladen Veinovic, Milan Milosavljevic, and Aleksandar Jevremovic: An Interactive and Collaborative Approach to Teaching Cryptology, 2013, Journal of Educational Technology & Society (Vol. 17, Issue 1)
[Abstract - This paper describes the implementation of a novel module for the CT2 educational software that provides the ability to communicate over the local computer network and the Internet from within CT2. The solution is used to let students interactively and collaboratively work on solving cryptologic problems. The approach tested in the classroom setting was evaluated and leads to better final grades and an increase in students' interest for this area.]
