CS 341: History of Computing in England Program: Cryptography

Modern cryptographic systems allow parties to communicate in a secure way, even if they don't trust the channels over which they are communicating (or maybe even each other). Cryptography is at the heart of a huge range of applications: online banking and shopping, password-protected computer accounts, and secure wireless networks, to name just a few. In this course, we will introduce and explore some fundamental cryptographic primitives. Topics will include public-key encryption, digital signatures, code-breaking techniques (like those used at Bletchley Park during WWII to break the Enigma machine's cryptosystem), pseudorandom number generation, and other cryptographic applications. Prerequisite: Computer Science 201 and 202. (Mathematics 236 will be accepted in lieu of CS 202)
