Topic

Goals

Using selected examples, students get an introduction into cryptography and data security based on cryptography. Some examples show insecurities of crypto-protocols, which result from naive use of crypto-systems. RSA, the most well known public-key cryptosystem, serves as the main example. The multiplicative property of RSA on the one hand makes lots of protocols, which can be found in the literature, insecure, but on the other hand it enables solutions to entirely new problems.
To prepare the experiments, the students get detailed scripts and do some exercises.
Then the students program the most important algorithms using a program framework, which saves them from having trouble with less interesting peripheral programming work.
The experiments are finished by a discussion about the results.
