Cryptography - Provable Security
We discuss several advanced security concepts like semantic security and plaintext indistinguishability. We also describe several techniques to design cryptosystems that meet these strong security requirements. In particular, we discuss one-way functions, pseudorandom generators, and pseudorandom functions. Finally, we compare the security of cryptosystems used in practice (like AES and RSA) with advanced security concepts.

This course will make use of the literature given below. Beside this, there will be no lecture notes for this course. Extensive lecture notes in cryptography of Luca Trevisan are available online.
Dates for oral exams have to be planned individually. To request a date, send a timely request to Claudia Jahn and the second professor for the exam, using an appropriate e-mail form from https://cs.uni-paderborn.de/en/studies/formalities/examination-dates/.
Make sure you are registered for the exam within the PAUL system before requesting a date for your examination.
Here we will publish the home exercises. Note that we won't publish any solutions to these exercises. Solutions to selected exercises will be discussed in the tutorials. You can submit your solutions in the box at F2.108. We encourage submissions of solutions by small groups of up to four students.
The first exercise will take place on April, 2017-04-18.
