Benedikt Wolters took 2nd place and was awarded 1000 Euro for his Bachelor thesis "Distributed Authorization Management for Secure Sensor Data in the Cloud".
In his thesis, which was supervised by Martin Henze and Rene Hummen, Benedikt enables administrators to securely maintain a federation of Wireless Sensor Networks (WSNs) from a single location via an untrusted cloud.
This provides administrators with a convenient and reliable way to keep WSN configurations consistent despite huge geographical distances between them.
Roman Matzutt took 3rd place for his Master thesis "Design and Implementation of Secure Decentralized Bitcoin Mixing" and was awarded 500 Euro.
Roman enhanced and implemented the CoinParty protocol which allows Bitcoin users to securely enhance their privacy by providing a secure and distributed mixing service.
Such services unlink the user's cash flows from their identities in Bitcoin's publicly readable transaction ledger, the blockchain.
The thesis was supervised by Henrik Ziegeldorf.
CoinParty was completely developed by COMSYS and the prototype is now available on GitHub.
The whole COMSYS team thanks Benedikt and Roman for their great performance and congratulates for their outstanding achievements!
