In the age of digital surveillance, apps boasting end-to-end encryption such as WhatsApp and Telegram have flourished. What are these tools, and how do they work? How have developments in modern computing and mathematics affected the field of cryptography and impacted privacy and safety in modern society?
Explore modern cryptographical tools such as ElGamal encryption and the Diffie-Hellman key exchange or the RSA cryptosystem with a focus on the interplay between privacy and security, including how governments and law enforcement agencies respond to new technological developments. As you and your peers develop your own cryptosystems or product ideas that solve an issue in modern cryptography, you simultaneously consider the technological and social implications of your work by looking deeply into its potential long-term impacts on cryptography and how it may complicate the balance between privacy and security.
