Bringing a calculator is advisedDear students, for the Re-Exam we do advise to bring your non-programmable calculator. There might be a few numbers where this is going to be helpful and too many points were lost on miscalculations on the last exam. Best of luck and see you tomorrow.

Read more We have received questions via the feedback option and during the office hour session, and since this is of importance to all of you we would like to provide answers and clarifications here. In a nutshell, you should consider everything that happens before 04.05.2020 as a test-run, as we do not have any prior experience in online teaching. We rephrased the most common questions. ================= Q: Do I have to watch the video lectures as they come out? Even before the official start of the semester on 04.05.2020? Will I have a disadvantage from not watching the videos before the official start of the semester? A: No. Everything that happens until 04.05.2020 is absolutely voluntary and you will be at no disadvantage if you ignore this lecture until then. Everything that happens until then should be considered a service from us to you (and a test-run for us at the same time). We will set up a calendar with suggested viewing dates for the videos, I.e. when and which lectures you should watch starting from the 04.05. We hoped that our first news board post made it clear that everything which happens before the 04.05 is non-mandatory, but we stress it here once more. ================= Q: At which pace will lectures and exercise sheets be uploaded? In the course Nebenläufige Programmierung all recorded lectures from last year were already made available online. A: We do not have pre-recorded lectures from last year, and right now we are essentially putting the Chapters online once we are finished recording and editing them. The intention is that anyone who wants to watch them can watch them, in the same way as you can watch any other online lectures. But this comes at no obligation for you to watch them as they come out. Regarding the exercise sheets, note that working on exercise sheets is entirely voluntary and the “scheduled” hand-in date (if you want feedback on your solutions) for the first sheet is the 08.05. ================= Q: What is my workload going to be for this lecture? A: In a normal semester there would be 2 lectures per week, i.e. 3h of lecture per week. This year the summer semester will be 11 weeks (04.05-17.07). However, due to the different format of the lecture this year we will try to keep the amount of video lectures for you to watch at or below 2h per week and count on you participating the weekly 1h Q&A session, which takes place on Mondays at 1pm. Apart from that, we offer exercise sheets and the weekly office hour (Thursdays from 1pm to 5pm) which replaces the tutorials. As we are still receiving feedback, the times might be subject to change, but any changes will be announced. ================= Q: Can you announce on the news board when new lectures go online? A: We made an announcement when the first set of recorded lectures went online, but abstained from announcing the following lectures as we didn’t want to convey the impression that it is mandatory to watch them. Unless people start complaining about too much spam we will announce new recordings from now on. ================= Q: How much material will the midterm exams cover? A: A preliminary (non-binding) date for the first mid-term is 04.06, the preliminary date for the second one is 02.07. So both mid-terms cover around 4 weeks of material, or 8-9h of video and 4 exercise sheets if you want so. But whether the mid-terms happen at all depends on the development of the Coronavirus situation. =================
All this said, would also like to ask for your understanding that these are difficult times for us as well. |

Cryptography
Lecture Period
The lecture period will start Monday 04.05.2020 and end Friday 17.07.2020. For your convenience, lectures will be put online once they are ready and you can watch them at any time. We will put suggested viewing dates for the lectures into the timetable.
Course Overview
Instructors: Nico Döttling, Antoine Joux and Benoit Cogliati
This lecture will provide an introduction to the field of cryptography. Modern cryptography is the study of the design and analysis of systems with a guaranteed resilience against adversarial abuse. During the run of the course, we will cover the following topics:
- Historic ciphers and the development of cryptography as a science
- A crash course in probability theory
- Private Key Encryption and Pseudorandomness
- Hash Functions and Authentication
- A crash course in algebra
- Public Key Encryption
- Digital Signature Schemes
- Advanced Concepts of Cryptography
Online Lecture
Due to the COVID-19 situation, this lecture will be online-only. Since 150+ attendants are too many to deliver the lectures live, the main lecture material will be delivered in the form of pre-recorded videos. While we have not tested this yet, we will try to set up a zoom call every Monday at 13:00.
This is the perfect opportunity to ask your questions since a lecturer will be present.
Exercises
There will be a weekly, voluntary exercise sheet covering the material of the lecture. You will be able to submit these exercise sheets. Tutors will give you feedback, but the sheets will not be graded. The amount of detail in the feedback depends on how many people submit their sheet.
Office Hour
There will be an office hours every Thursday at 13:00. We encourage you to join our discord server at that time and work together on the exercises. During that time tutors will be present to answer your questions or give you small hints.
Literature
You can find complementary literature in the Semesterapparat.
