Course Applied Cryptography
Internal number INFM221.a	Type/mode Lecture
Lecturer Prof. Dr. Frank Schaefer	Language of instruction German
Extent (ECTS/SWS) 4/3	Assessment Module exam
Content 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.
