Introduction to Cryptography by Christof Paar

The 24 lectures give a comprehensive introduction to modern applied crypto. Only high school math is required to follow the lectures.

The videos are mostly self-contained, i.e., you should be able to follow most of the material without additional resources. However, we recommend the course textbook, "Understanding Cryptography" by Christof Paar and Jan Pelzl. Please see

The English version of the crypto lectures was taught in the 2010/11 academic year at Ruhr University Bochum in Germany. We have Europe's largest programs in IT security, with 200+ new bachelor and master students annually. The videos show the two-semester introductory courses for our B.Sc. and the M.Sc. IT security students. There is *no* tution for either program, however, students must pass a German language exam (sorry). More on RUB:

As an excellent learning tool, we highly recommend:
