Wellcom-Phd-2007

2 Ph.D. positions open at UniK, deadline 11. April 2007

UniK offers two Ph.D. positions of 3 years duration in the area of proximity services.

  • Device Community
  • Social Community

Ph.D. researcher in the area of Device Community

Seamless authentication to personalised services is a major challenge for all systems. While GSM/UMTS has a SIM based authentication, wireless authentication to WLAN (Wifi, WiMAX,...) uses a range of potential authentication mechanisms.

The focus of this work is to elaborate on SIM based authentication mechanisms and their distribution in wireless networks (Bluetooth, RFID/NFC, Wifi), in order to ensure a seamless service access. Special focus will be on exploiting the capabilities of Near Field Communications (NFC) for key exchange, used for authentication, authorization and admittance.

The SIM's functionality can be extended to build device domains in order to provide easy content access. Mechanisms for keeping communities working will be part of potential tasks.

Envisaged tasks:

  • Theoretical: cryptography, key management, networking basics
  • Implementation: use NFC (http://www.nfc-forum.org, NFC tutorial)
  • Standardisation: ECMA, NFC key exchange
  • Testbed: show how a device domain is built, test and validate management methods

Ph.D. researcher for Social Communities

Managing social communities and conducting communication with the members of these communities are some of the key challenges in future personalized service access scenarios. The social communities are comprised of various social groups based on one's preferences, tastes, interests. Ubiquitous computing and pervasive Internet have enabled access to diverse service world in every situation. People now create own social groups and become member of many such groups in the digital world. Managing such groups and sharing resources like documents, photos, videos etc. with members of numerous social groups is currently hampered due to complex document ownership handling. Handling differential access rights is a challenging task, which is the main objective of this PhD research. The introduction of semantics and the representations in .rdf and .xml allows describing user preferences and relations to characterize the social context of a person. Linking these user preferences and relations to the service world described by the Semantic Web and Semantic Web Services will be the final challenge.

Envisaged tasks:

  • Theoretical:
    • Model for user community and user preferences based on semantic annotations
    • Establish a virtual service depository, containing access rights to documents and services
  • Implementation: establish semantically supported communities and user preferences
  • Demo: establish service access
  • Introduction to social communities (.pdf)Δ

General information

The research is performed in the context of the European ITEA WellCom project, which is financed in part by the Norwegian Research Council. The first Ph.D is also supported by Telenor. The researcher will work together in a team with the international project participants, project participants from Telenor, BeepScience, UniK students and researchers.

The work will be conducted in the Mobile Networking Group at UniK (Kjeller, Norway). Salary is after the rules from the state. The application (norwegian or english) with CV, transcript of records, and names of two references should be sent to: or UniK, Boks 70, 2027 Kjeller, Norway. Mark application with "Device Community" or "Social Community". Deadline 11. April 2007.
