Post-Quantum Cryptography

The analysis and design of post-quantum secure cryptographic systems is becoming increasingly important and urgent, as sufficiently powerful quantum computers could be available in the next 10 to 20 years. In particular, the chair focuses on systems of symmetric cryptography, which currently receive less attention in research. Nevertheless, it has been shown in recent years that the availability of sufficiently powerful quantum computers also affects the security of many classical symmetric algorithms. Not only "Grover's algorithm" can be used for this purpose. In certain attack models, algorithms such as "Simon's Algorithm" can be even more effective.
