In this video, we show the basics of cryptology (cryptology = cryptography and cryptanalysis).

This video here gives an introduction to a very special part of modern asymmetric cryptography: We discuss the Diffie-Hellman-(Merkle) key exchange. First, we give an introdiction to the key exchange paradox. After that, we give a brief introduction in the history of the Diffie-Hellman key exchange. Then, we explain the basic idea with colors. After that, we give an introduction into the needed mathematics and we explain the Diffie-Hellman key exchange in detail. Finally, we show different templates in CrypTool 2 that interactively present the Diffie-Hellman key exchange.

Hint: This video here uses as finite group the cyclic multiplicative group built by the powers of a primitiv root r modulo n. This is an easy to understand example of a group which can be used for
