Decentralized Systems and Network Services Research Group
Under the term "Decentralized Systems and Network Services" we understand distributed and networked technical systems that span over more than one administrative domain. Hence, their operation depends on more than one party. Our research focuses on:
- Blockchains, consensus and peer-to-peer networks
- Network Security Monitoring
- Secure and privacy-aware computing in partially trustworthy environments.
At the 3rd International Workshop on Cryptocurrencies and Blockchain Technology (CBT'19) on 26th and 27th Septembre, 2019, co-located with ESORICS 2019 we presented our work "TEE-Based Distributed Watchtowers for Fraud Protection in the Lightning Network". We propose TEE Guard, a distributed watchtower solution for the Lightning Network that utilises Trusted Execution Environments.
Out conference submission "Access Control for Binary Integrity Protection using Ethereum" has been published in the respective proceedings. Furthermore, our contribution received the "Best Paper Runner Up" award.
The SICK-Wissenschaftspreis for the best thesis 2017 was awarded to Matthias Grundmann for his master thesis titled "Analysis and Evaluation of Analysis Methods for Topology Inference in the Bitcoin Peer-to-Peer Network" at the annual Tag der Informatik. In this thesis he discussed possibilities for dertermining the topology of the Bitcoin peer-to-peer network and introduced two new methods to accomplish this.
On the IEEE International Conference on Blockchain and Cryptocurrency from 14-17 May 2019 in Seoul, South Korea we presented our publication "Banklaves: Concept for a Trustworthy Decentralized Payment Service for Bitcoin", which explores a new way to implement a second layer architecture for cryptocurrencies using Trusted Execution Environments.
