In this seminar we want to work with you on very current topics in secure identity research that are all connected to our individual research topics. Specifically, we will present topics in the fields of:

  • Behavioral Authentication
  • Access Management Systems
  • Fingerprinting in P2P Networks
  • Self-Sovereign Identity Ecosystem

Depending on the topics you will be divided into groups to work on these topics and finally write a scientific report summarizing your results. The major goal is to learn scientific working and writing so we will have a close supervision, especially in terms of the DOs and DONTs in paper writing :)

The topics for the upcoming winter semester will be available soon! In case you can not wait, you are invited to come and talk to us via mail, phone, or in person!

Additionally, in the literature section you can already find some examples of our previous publications in the context of the proposed topics.

Please refer to EvaP for the evaluation of previous iterations of this seminar. Please be aware, that we usually have the Secure Identity Lab during summer semester and this seminar (Hot Topics in Secure Identity Research - HotSIR) during winter semester.


Bitcoin P2P Network

Gotta Catch’em All! Improving P2P Network Crawling Strategies

Characterising Proxy Usage in the Bitcoin Peer-to-Peer Network


Behavorial Authentication

FIDOnuous: A FIDO2/WebAuthn Extension to Support Continuous Web Authentication

Beware of SMOMBIES: Verification of Users based on Activities while Walking

Under Pressure: Pushing Down on Me: Touch Sensitive Door Handle to Identify Users at Room Entry

Verification of Keyboard Acoustics Authentication on Laptops and Smartphones Using WebRTC


Self-Sovereing Identity Ecosystem

A Survey on Essential Components of a Self-Sovereign Identity

On the Relevance of Blockchain in Identity Management

A Quantifiable Trust Model for Blockchain-based Identity Management

The following disciplines will be considered for the overall grade:

  • intermediate presentation (15%)
  • final presentation (25%)
  • source code (20%)
  • project documentation (30%)
  • student activity (10%)


Our topic presentation will be on the 28.10.2021 in H.E 51/52 at 3.15pm.

The important dates for the respective presentations are still tbd, so stay tuned ;) Usually, the timeline and important deadlines and uploads are organized via Moodle.

In case you take part in the seminar we will regularly meet in individual groups. Typically, these meetings will be in person at the campus at individual times but can also be virtual spontanously, for instance.
