Information

Ziele, Inhalte und Methode der Lehrveranstaltung

Cryptography is the scientific study of techniques for securing digital information, transaction and distributed computations. Any modern communication system that claims to be "secure" builds upon cryptographic protocols and the hardness of certain mathematical problems. Although widely used and studied, the dominant position of the RSA algorithm crumbles in the presence of quantum computers, which exploit quantum properties to break its hardness assumptions.

As a response to this threat, two solutions are being extensively researched: post-quantum cryptography, based on mathematical problems that are hard for quantum computers, and quantum/relativistic cryptography, which harnesses the 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 its foundations (e.g. group theory, prime numbers, discrete logarithm, elliptic curves)
- Threats to modern cryptography (especially quantum computers)
- Post-quantum cryptography
- Quantum key distribution and unforgeable quantum money
- Mistrustful quantum cryptography
- Relativistic quantum cryptography
- Photonic implementation of quantum cryptography

The lectures will be complemented with exercises, that feature
- Pen-and-paper calculation
- Programming in Python and Matlab
- Quantum optics laboratory (depending on the number of students)
