Privacy Enhancing Technologies (WS 2023/24)
Table of Content
Content
The lecture Privacy Enhancing Technologies overviews modern cryptographic and non-cryptographic methods to increase privacy.
Privacy is the ability of an individual or group to seclude themselves or information about themselves.
This lecture covers basic privacy principles and mechanisms to increase a user's privacy. We will take a closer look at building blocks that provide privacy, including:
- Leakage of aggregate Data and Database recovery
- Differential Privacy and K-anonymity
- Multiparty Computation protocols
- (Fully) Homomorphic Encryption
- Privacy-Preserving machine learning
- Oblivious Pseudorandom Functions
- Regulation on privacy
- Blockchains
- TOR, traffic analysis
- Zero Knowledge Proofs

Lecture Exams (VO)
The VO exam is a written exam. Please find the exam dates and registration in TUGRAZonline.Practicals (KU)
In the practicals, you implement small projects related to the topics discussed in the lectures. The practicals consist of 3 assignmentsT1, T2, T3 solved in teams of 2 students.
You can earn a total of 100 points; the grading scheme is shown in the table below.
You will get a grade as soon as you hand in a solution to T1 by adding a git tag. Groups that do not hand in anything for T1 will not be given a grade and will be unregistered from the course. Note that handing in T1 (even an empty solution) is the only condition for “getting a grade”.
| Grade | 5 | 4 | 3 | 2 | 1 | |
|---|---|---|---|---|---|---|
| Min. Points | < 50 | ≥ 50 | ≥62.5 | ≥ 75 | ≥ 87.5 | of 100 |
Teams and Team Registration
The KU is done in teams of 2 students. You can use the IAIK discord, channel#pets to find team members. You then register your team at the TeachCenter.
Submission
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 starts with the assignment (T1, T2, T3), followed by a dash and a number. As an example, T1-1 is the label for the first assignment. As tags cannot be deleted, you may always update your final submission by increasing the appended number: T1-2, T1-3, etc. In the end, the tag with the highest number before the deadline counts.
Your submissions will be tested automatically by our test system. Thus, you need to respect and meet the file naming constraints of the individual assignments. Otherwise, the tests will all fail, and you will receive 0 points for the assignment.
After the hand-in of the last task, there will be a team interview for all 3 tasks. There, both team members need to be able to explain their solution to each assignment.
