Class Overview: We will cover materials of modern cryptography, and some applications to security. In particular, students will be exposed to how to formally define security property, how to construct a cryptographic scheme whose security can be rigoriously argued, how to use a cryptographic building block to realize a more complex functionality, and some real world applications, including the recently emerged disruptive technology -- blockchain and cryptocurrency.
A tentative list of topics includes:
