Applied Cryptography

4
CSE121

In this course on Applied cryptography, we will learn about the following topics:

  1. Security notions, adversary powers, Perfect security
  2. Stream ciphers, block ciphers, hash functions
  3. Message authentication
  4. Public key cryptography
  5. Some interesting Cryptograhic protocols

Some mathematics will be required, and will be taught as needed. No background is necessary. Interest in mathematics and theoretical computer science is a prerequisite.

1. Students are able to analyze weak ciphers and break them.
2. Students are able to summarize the design principles of block ciphers, stream ciphers and hash functions.
3. Students are able to explain why some public key schemes (such as RSA and El Gamal) work.
