Administrative Information

Lecture Exams (VO)

In order to get a grade for the VO, you take a written, 60-minute exam. This is a closed-book exam, i.e., you are not allowed to bring any material such as notes or books. You can earn a total of 48 points: 8 for each of 6 question pages. Each area (Cryptography, System Security, Network Security) is represented by 2 question pages.
Grade 5 4 3 2 1
Min. Points < 24 ≥ 24 ≥ 30 ≥ 36 ≥ 42 of 48
You can find upcoming exam dates in TUGRAZonline.

Practicals (KU)

In the practicals, you implement small projects related to the topics discussed in the lectures. The practicals consist of 3 assignments P1, P2, P3 solved in teams of 2 students.

Teams and Team Registration

The KU is done in teams of 2 students. You can use the IAIK Discord, channel infosec-groupsearch to find team members. You then register your team in the TeachCenter. Your team will be assigned a random teaching assistent for the assignment interviews.


You are given access to a git repository in our teaching git where you have to push your submission. The required content is discussed in the Kick-Off lectures. You must mark your final submission by tagging it in git. The tag label is based on the assignment: P1, P2, and P3. As an example, P1 is the tag label for the first assignment. Before the deadline, you can change your tag if need be. Your submissions will be tested automatically by our test system. Thus, you need to respect and meet file naming constraints of the individual assignments. Otherwise, the tests will all fail and you will receive 0 points for the assignment. After hand-in of each task, there will be a team interview with your teaching assistant. There, both team members need to be able to explain your solution.


You can earn a total of 48 points: 16 for each task. The grading scheme is shown in the table below. You will get a grade as soon as you hand in a solution to P1 by adding a git tag. Groups that do not hand in anything for P1 will not be given a grade and will be unregistered from the course. Note that handing in P1 (even an empty solution) is the only condition for “getting a grade”.
Grade 5 4 3 2 1
Min. Points < 24 ≥ 24 ≥ 30 ≥ 36 ≥ 42 of 48
We treat the involvement of ChatGPT and similar tools the same way as the involvement of another natural person. That is, for involvement that qualifies as plagiarism or an impermissible level of assistance, the consequences will be the same in both cases to the strictest extent possible.

Contact and Communication

For questions regarding the courses we have the following communication channels:
  • TU Graz Teach Center: Official Announcements, FAQs, Forum and more.
  • Discord: IAIK server, channel infosec for all questions regarding lectures and exercises.
  • Discord: IAIK server, channel infosec-groupsearch to find team members for the exercises.
  • Mail your teaching assistent for questions and problems regarding your team or topic. Please use Discord for questions regarding the exercise topics, as other students might be interested as well.
  • for administrative questions (specific to your situation). Please use Discord for questions that might be of interest for other students as well.
