Lecture 11: Cryptology

The crypto lecture has three or four parts, depending on how fast we progress:
  1. Early Cryptography until polyalphabetic cyphers.
  2. The Enigma: (mostly the history of this fascinating story.
  3. Public Key: Diffie-Hellman and Rivest-Shamir-Adleman. How do these protocols work?
  4. If time permits, we look also at the problem of error correction or what quantum cryptography is (more informal).
Cryptology is a hot area of math. It has lots of overlap with engineering, with computer science and politics! But it is now mostly hard core mathematics. It is a place, where number theory plays a major role.
