TSIT03 Cryptology
This first course in cryptology gives an overview of existing algorithms and the requirements they should meet. Some algorithms are treated in depth while others are treated more at an introductory level, a detailed list over the course content can be found here.
The course is given in period HT1. The literature and lectures are in English, as are the training lessons.
Required courses
Algebra and Probability Theory. TSIT02 Computer Security and Discrete mathematics are recommended, but not strictly required.
