In this seminar, we will discuss current advances in cryptography as well as their impact on society. After an introduction of the overall area and the goal of the seminar, small groups of 2-3 students will select an individual topic and prepare a technical presentation (~45min) as well as lead a discussion (~45min) on the societal benefits, risks and trade-offs of the presented technologies. At the end of the seminar, a report (6-10 pages, double column format) summarizing the selected topic and the discussion must be handed in.

Topics include:

  • Cryptocurrencies
  • Smart contracts, NFTs and Web3.0
  • Self-Sovereign Identity & European Digital Identity
  • „Crypto wars“: end-to-end encryption vs. surveillance
  • Apple‘s CSAM detection
  • Privacy-preserving analytics
  • Privacy-preserving contact tracing & privacy-preserving analytics for GAEN
  • Cryptography for #MeToo / Callisto protocol

Students are also invited to propose their own topics.


A more detailed overview of topics and reading suggestions is given in our Moodle.


Basic knowledge of cryptography. Attendance of the Cryptography lecture (every winter term) is beneficial but not necessary.


The grade will be based on the presentation and discussion (60%), the accompanying report (30%) and active participation in the seminar (10%).


The seminar takes place on Monday 13:30-15:00 at G3.E15 (currently, no hybrid/online option is planned)
