Codes and Ciphers

Tanya Yurchenko

Sasha Kirillov, PhD

In this course, we describe the art of secret writing - cryptography. We discussed codes throughout history, from encrypted notes of Caesar to secret correspondence of French kings to the Enigma machine of WWII and showed how these codes can be broken. We gave students the tools to create your own codes and cyphers.

In the last lecture, we discussed uses of cryptography in the modern world, from AES encryption used in financial transactions to public-key cryptography used for secure online communication.
