CS 255: Introduction to Cryptography Stanford University Winter 2023 This course offers an introduction to cryptographic techniques used in computer security, covering encryption, message integrity, digital signatures, key management, and more. It is suitable for advanced undergraduates and masters students with some proof techniques and programming experience. Cryptography is an indispensable tool for protecting information in computer systems. This course explains the inner workings of cryptographic primitives and how to use them correctly.

This course is an introduction to the basic theory and practice of cryptographic techniques used in computer security. We will cover topics such as encryption (secret-key and public-key), message integrity, digital signatures, user authentication, key management, cryptographic hashing, Network security protocols (SSL, IPsec), public-key infrastructure, digital rights management, and a bit of zero-knowledge protocols.

Optional readings can be found in the textbooks denoted by KL and AC in the syllabus below. The optional AC book, by Boneh and Shoup, is more advanced (and free) and is intended for students wishing to go deeper. The [online version of the course](https://crypto.stanford.edu/~dabo/courses/OnlineCrypto/) is another resource for the material covered in class.

- **Boneh-Shoup (AC):** (free) *[A Graduate Course in Applied Cryptography](https://cryptobook.us) (V 0.5)* by D. Boneh and V. Shoup
- **KL:** *[Introduction to Modern Cryptography](http://www.cs.umd.edu/~jkatz/imc.html)* (2nd edition) by J. Katz and Y. Lindell.  The course is self contained, however a basic understanding of probability theory and modular arithmetic will be helpful. The course is intended for advanced undergraduates and masters students. Students are expected to have experience with basic proof techniques and some programming experience. Students can supplement the lectures with an [online version of the course](https://www.coursera.org/learn/crypto) (MOOC) that covers some of the material.

The following books can be used to supplement the lectures:

- Optional: *[Introduction to Modern Cryptography](http://www.cs.umd.edu/~jkatz/imc.html)* by J. Katz and Y. Lindell.

Note that the textbooks do not cover all the material discussed in class.
