Module New Module, Computer Science (Master) (ER 6)

In the course the main cryptographic algorithms are presented. Blockciphers (DES, AES), Modes of Operation (ECB, CBC, Countermode), Hash functions, MACs, public key algorithms (RSA, Diffie-Helman, ElGamal) are covered by the lectures.
Then we will look at and analyze applications in IT-security, which use cryptography: E/mail-security (eg. PGP, S-MIME), web-security (SSL), network-security (IP-Sec), authentication mechanisms.

The course consist of lectures (around 2/3) and exercises (around 1/3). In the exercises the mathematical techniques introduced in the lecture will be trained.

This course teaches foundations about codes and codings as well as basic algorithms for source coding, channel coding and line coding. The lecture focuses on the following topics: information and coding theory, data compression, error detecting and correcting codes, limits of data transmission.
