Cryptography is the art, or science, of secret communication. But what is secret communication? How can it be achieved? What mathematical assumptions underlie security? This course will cover the foundations of modern cryptography, including one-way functions, pseudo-random generators, cryptographic hash functions, and their application to the construction of cryptographic primitives such as public and private-key encryption schemes, digital signature schemes, message authentication codes, and more.
Prerequisites: Ma 1b. CS 21, CS 38 or equivalent recommended.
This is a 12-unit course. In addition to attending 3 hours of lecture weekly, students are expected to:
