Secure and Private Collaboration through DNS

The mDNS-SD Privacy Extension replaces many multicast packets by unicast packets sent to pre-paired devices only, thus not only distributing less privacy-sensitive data in the network, but also reducing the amount of broadcast traffic that uses a considerable amount of resources on modern wireless networks.

[Master] Design and Analysis of a secure multi-party communication protocol

In the past years digital communication became an important aspect in every day life. Everything is shared and discussed in groups of friends, family or business part- ners without a proper way to protect that information. This master thesis introduces the first secure robust multi-party communication protocol which mimics a physical conversation with the help of a Diffie-Hellman key tree and social behaviours. Robust- ness against offline group members is reached by taking advantage of...

SARA: Software Archiving of Research Artefacts

The SARA project (Software Archiving of Research Artefacts) aims to develop a new scientific service that allows long-term access and publishing of research data and scientific software. Its main focus is on software tools that support the processing and analysis of research data. In biological research, for example, measured data is collected and processed with the support of computers. Within Computer Science and Electrical Engineering, the different versions of newly developed software need...

WISEchat

Chat — instant messaging, audio and video calls — have come to form an integral part of our daily life. Most people use closed systems for these needs, which is acceptable for private use, but fail the privacy requirements for official use in a research or teaching environment. However, this does not have to be the case: WISEchat offers the security, comfort and availability demanded by a modern university based on the open, federated Extensible Messaging and Presence Protocols (XMPP).

[Bachelor] Mapping different datatypes ensuring secure cloud storage

In this thesis two generic approaches on how to store different datatypes to a cloud storage are proposed, thereby utilizing Treetank. As part of this thesis implementations for the proposed approaches have been implemented to evaluate their practicability and search out strengths as well as weaknesses. Current cloud storage systems, security concerns towards privacy, stability and integrity of data shared with “the Cloud” is discussed. An overview of Treetank, that originally was designed to be...

PACMAN: Privacy and Anonymity in Communication, Mobile, and Ad-hoc Networks

In the presence of ever increasing volumes of traffic, legal threats by copyright holders, and QoS demands of customers, network service providers are urged to apply traffic classification and shaping techniques. Such actions violate the End-to-End and Net Neutrality principles and thus threaten freedom of speech and the foundations of democracy.

In this project we strive to enhance privacy and anonymity in communication networks. We show that the user vs ISP war consumes vast amounts of...
