Seminal Papers in Cryptography

In this proseminar we study a selection of seminal research works in cryptography—starting with the invention of public-key cryptography in the 1970s and making our way towards the present. We discuss the novelty of these research results when they were first published as well as how they have shaped our understanding of modern cryptography.
