About the Course

Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption....

Provides a comprehensive introduction to cryptographic history, current technology, best practices and known attacker techniques. A great deal of material is covered in a relatively compact program.

Cutting edge cryptography topics. Good explanations and slides, but pause button is highly recommended. Can be a bit too mathematical for the general public, and not very formal for mathematicians.
