As the world moves to develop quantum computers, we must prepare for the inevitability that an „attacker” will have access to this technology before we will. Current cryptographic standards are not secure against quantum attacks. We need post-quantum cryptography: the study of cryptographic protocols which can be implemented on classical computers and be resistant to quantum attacks.
In this course, we will cover the mathematics underlying three promising directions for post-quantum cryptography:
- Codes,
- Lattices,
- Isogenies.
We will study the computational hard problems underlying these families of cryptographic protocol and look at candidate protocols which may be standardized in the future.
