The Joy of Cryptography

The Joy of Cryptography

These are lecture notes for cs427 at Oregon State University, an introductory course in cryptography at the advanced undergraduate level. By reading and studying these notes, you should expect to learn how to: State and interpret the standard formal definitions for the most common cryptographic security properties (privacy and authentication). Formally prove security properties of sound cryptographic constructions, and break the security of unsound ones. Choose the appropriate cryptographic primitive for a task (block ciphers, hash functions, MACs, public-key encryption, etc.) while avoiding common pitfalls. Along the way, you will also learn how the most common cryptographic constructions work. You will get the most out of these notes if you have a solid foundation in standard... Show More
