Objective

Course purpose
Cryptology is an alternative to the applied mathematics course in information and communication technology. In this course, you will focus your knowledge on the mathematics needed in information security and especially encryption methods.

Course competences
EUR-ACE Knowledge and understanding
• knowledge and understanding of mathematics needed in information and communication technology
• knowledge and understanding of engineering fundamentals underlying the specialisation, at a level necessary to achieve the other programme outcomes, including some awareness at their forefront
EUR-ACE Engineering Practice
• understanding of applicable techniques and methods of analysis, design and investigation and of their limitations in their field of study

Learning outcomes
You know and understand the mathematical principles of the most common encryption methods. You can solve simple linear congruences. You know how to choose the encryption method that suits the situation and you have the skills to deepen your knowledge independently.
