Cryptography
Cryptography studies the design of distributed systems with resilience against arbitrary adversarial abuse. What makes this task challenging is that at the time a scheme is designed, it is not yet known how an attack may look like or what resources are available to an adversary.
This course is an introduction into modern cryptography and covers fundamental concepts such as
- Security models and security proofs
- Information-theoretic and computational security
- Pseudorandomness
- Private Key Encryption
- Authentication
- Public Key Encryption
- Signature Schemes
- Zero-Knowledge Proofs
- Basic Multiparty Computation Protocols
Location and Time: Raum 002.1 Geb E1 3 Monday 10.00 - 12.00 and Wednesday 16.00 - 18.00 starting on 12.04.

Exams:
There will be two midterm exams for the lecture. Getting a passing mark of 4.0 for at least one of these two exams is necessary to qualify for the final exam.
In addition, the mark of the better midterm exam will count for 30% of the final mark, while the final exam will count for 70% of the mark.
There will also be a re-exam for the final exam, allowing for improvement of the corresponding 70% of the total mark.
