1. 21. Consensus Algorithms in Dynamical Network Systems

   Författare :Håkan Terelius; Karl Henrik Johansson; Alexandre Proutiere; Julien M. Hendrickx; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Dynamical network systems are complex interconnected systems describing many real world problems. The current trend is to connect more and more systems together, and at the same time requiring continuous availability. To this end, it is crucial to understand the dynamic behaviors of networked systems. LÄS MER

3. 22. Query Processing for Peer Mediator Databases

   Författare :Timour Katchaounov; Tore Risch; Tamer Özsu; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data integration; mediators; query processing; Computer science; Datalogi;

   Sammanfattning : The ability to physically interconnect many distributed, autonomous and heterogeneous software systems on a large scale presents new opportunities for sharing and reuse of existing, and for the creataion of new information and new computational services. However, finding and combining information in many such systems is a challenge even for the most advanced computer users. LÄS MER

4. 23. Privacy Issues in Decentralized Online Social Networks and other Decentralized Systems

   Författare :Benjamin Greschbach; Sonja Buchegger; Melek Önen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Privacy; Online Social Networks; Decentralized Online Social Networks; Computer Science; Datalogi;

   Sammanfattning : Popular Online Social Networks (OSNs), such as Facebook or Twitter, are logically centralized systems. The massive information aggregation of sensitive personal data at the central providers of these services is an inherent threat to the privacy of the users. LÄS MER

5. 24. Security and trust mechanisms for groups in distributed services

   Författare :Claudiu Duma; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : Group communication is a fundamental paradigm in modem distributed services, with applications in domains such as content distribution, distributed games, and collaborative workspaces. Despite the increasing interest in group-based services and the latest developments in efficient and reliable multi cast, the secure management of groups remains a major challenge for group communication.

7. 25. Privacy Analysis and Protocols for Decentralized Online Social Networks

   Författare :Benjamin Greschbach; Sonja Buchegger; Simone Fischer-Hübner; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; privacy; online social networks; decentralization; Computer Science; Datalogi;

   Sammanfattning : Decentralized Online Social Networks (DOSNs) are evolving as a promising approach to mitigate design-inherent privacy flaws of logically centralized services such as Facebook, Google+ or Twitter. Common approaches to implement a DOSN build upon a peer-to-peer (P2P) architecture in order to avoid the central aggregation of sensitive user data at one provider-controlled location. LÄS MER
