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.
