Information

Ziele, Inhalte und Methode der Lehrveranstaltung

Cryptography is the art of communicating or running a computation while providing certain security guarantees against unauthorized parties. Such guarantees include anonymity, confidentiality, authenticity, one-timeness, randomness and consensus. Any modern communication system that claims to be "secure" builds upon cryptographic protocols and the hardness of certain mathematical problems.

Although widely used, the security of dominant algorithms such as RSA crumbles in the presence of quantum computers, which exploit quantum properties to break their hardness assumptions. As a response to this threat, scientists are developing solutions that harness the fundamental laws of quantum mechanics and special relativity to provide new security guarantees. Milestone protocols of this kind include quantum key distribution, unforgeable quantum money and relativistic bit commitment.

This lecture will give an introduction to state-of-the-art classical and quantum cryptography, tackling the follow topics:
- Goals of security, definitions of trust
- Symmetric encryption and hashing
- Asymmetric cryptography and threats from quantum computers
- Quantum key distribution and unforgeable quantum money
- Mistrustful quantum cryptography
- Relativistic quantum cryptography
- Photonic implementation of quantum cryptography
- Quantum and side-channel attacks

Note: familiarity with the formalism of quantum information is recommended.
