O. Forster

Winter Semester 2002/03,
Department of Mathematics, LMU München
**Time and Room:** Mon, Thu 9-11, HS 138

**Problem sessions:** Monday 11-13, HS 132 (changed!)

**Crypto contest**

** Contents:**
After a survey of classical cipher systems
we will study modern block cipher crypto
systems and public key cryptography. 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)

**Detailed Contents**

** Prerequisites:**
Basic notions of algebra and analysis.
My course on Algorithmic Number Theory (SS 2002) is useful,
but not an absolute prerequisite.

** For:** Students of the International Master Program
in Mathematics,

Studierende der Mathematik und/oder Informatik nach dem
Vordiplom, sonstige Interessenten
