CS 6830
Cryptography

Course information provided by the 2025-2026 Catalog.

A rigorous introduction to the theoretical foundations of the cryptography that powers much of the modern world. As this is a theoretical class, the emphasis will be on formal definitions and proofs. E.g., what does it mean to communicate securely? Can I prove that I am who I claim to be without revealing additional information (such as information that allows others to impersonate me)?Topics include one-way functions, pseudorandom number generators, public-key encryption, zero-knowledge proofs, digital signatures, etc. We will also see some more exotic primitives, such as fully homomorphic encryption, and we might briefly discuss program obfuscation and/or cryptocurrency.


Prerequisites REF-FA25/Corequisites REF-FA25 general ease with algorithms and elementary probability theory, maturity with mathematical proofs (ability to read and write mathematical proofs). Corequisites: None.
