Read more Some people in the audience noticed that the solution provided for exercise 5.3 did not fulfill the constraints as set by the exercise (namely the PRF key having to be of length \lambda). We set this constraint by mistake which made the exercise harder than intended. Nevertheless, we just uploaded a solution for the exercise in the way it was phrased.

First Lecture Monday the 15.04.19The first lecture will take place on Monday the 15.04.19 |
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: Günter-Hotz-Hörsaal Monday 10.00 - 12.00 and Wednesday 14.00 - 16.00
