About this course: In the past, cryptography was mainly used by the military, secret service and diplomatic service. Today, in the age of internet, almost everybody is confronted directly or indirectly with cryptography. In this course, after a brief look on classical cryptography, we will study modern block cipher crypto systems (DES, AES) and public key cryptography. Public key cryptography plays an important role in electronic commerce, electronic banking and other kinds of modern data communication. It deals not only with secret coding of messages but also with digital signatures and authentification. Public key cryptography uses interesting mathematical methods from number theory and algebraic geometry (e.g. elliptic curves over finite fields)
