Administrative Information
The course is split into a theoretical part (the "VO") and a practical part (the "KU").
Lecture Exams (VO)
For the lecture (TUGRAZonline), there are regularly scheduled closed-book exams (written, 90 minutes). The slides from the download section are subject to examination.
Please find the exam dates and registration in TUGRAZonline.
Practical Part (KU)
For the practical part (TUGRAZonline), you will have to implement parts of the TLS protocol and a scenario in the context of privacy-enhancing technologies in C++. The tasks are to be solved in groups of up to 4 (four) people. At the end of the semester, there will be an assignment interview ("Abgabegespräch") in which you have to both explain parts of your implementation and show that you have understood the necessary concepts.
To participate in the practicals, every group has to register via STicS (Task 0).
Task Submission
Your tasks are split into a theoretical part and an implementation part. The theoretical part has to be submitted as PDF via STicS, for the implementation part you are given access to a Git repository in our teaching Git where you have to push and tag your submission. For more details we refer to the assignment sheet.Deadlines
