# Introduction to Cryptography

## Overview

Cryptography is an indispensable tool for protecting information in computer systems. This introduction to the basic theory and practice of cryptographic techniques used in computer security will explore the inner workings of cryptographic primitives and how to use them correctly.

## Topics Include

- Encryption (single and double key)
- Pseudo-random bit generation
- Authentication
- Electronic commerce (anonymous cash, micropayments)
- Key management, PKI, zero-knowledge protocols

## Grading

There will be three written homework assignments and two programming projects. Final placement in the class will be determined by the following formula:

0.35 H + 0.35 P + 0.3 F

where:

- H is your average score on the four written homework assignments.
- P is the weighted average grade on the two programming projects.
- F is your final exam score.
