**Introduction to Cryptology**

This course is an introduction to the mathematical theory of secure communication. Topics to be developed will include:

- Classical cryptographic systems: substitution, transposition, polyalphabetic systems.
- Brief introduction to Shannon's information theory.
- Introduction to modern (public key) cryptology.
- Intoduction to complexity theory.
- One-way and trapdoor functions.
- Knapsacks (an example of an NP problem).
- RSA
- Diffie-Helman: discrete logarithms
- Attack methods.
- Some ideas from probability theory.
- Elliptic curves and ECC
- Other topics as time permits (e.g., lattice cryptosystems).

Course requirements include: weekly homework assignments; a midterm exam; and a project to be done by each student or group of two students. Course will involve some computer use, particularly of Mathematica. (Alternatively, download pari.gp)
