Summary on the progress of the project
The aim of this project is to develop platform solutions for meaningful security, privacy, and trust constructs for the new types of social D2D-based applications. The research has proceeded on three parallel tracks that intertwine as concrete end user applications. First, security solutions have been defined on the protocol level, especially for the most challenging network topologies, where cellular connectivity may become unreliable. Second, practical software solutions for forming trusted connections between mobile devices have been defined.
Within this project, the opportunities and threats that D2D brings to proximity-based end user applications have been studied with user-centric methods. An extensive scenario work resulted in over 20 examples of how D2D could be used for new purposes. Three of them have been developed into full-fledged mobile applications. As these were finalized, we run two parallel large-scale user trials in collaboration with Brno University of Technology (BUT) in Czech Republic. Additionally, an extensive online survey of one of the few commercially available D2D-based services (Nintendo DS3 StreetPass) has been conducted to learn from the relevant user experiences. Absorbing the gaming context has brought inspiring elements of gamification to the designs of the applications under development. The above activities have resulted in a significant number of research publications.
Considering the realized risks, there have been a few minor setbacks with regards to the personnel. One security-oriented researcher had to leave the project because he was offered a permanent position in Nokia. New recruitments have been made quickly at that time.
In general, the collaboration has been intensive, which was steered by the weekly project meetings with also people from Brno University of Technology (BUT) and Intel Finland taking part. A semi-public seminar was held in May 2015 for the collaborators and stakeholder companies to report on the results of the first year and plan for the second year of the project.
The first researcher mobility (3 persons from TUT) took place in August 2014 to BUT to establish a novel academic contact with this strong group, with which the technical prototyping work has begun. The second researcher mobility (Ms. Olga Galinina) to University of Manitoba, Canada took place in May-July 2015 followed by another visit (Mr. Aleksandr Ometov) Sep-Dec 2015 to BUT. Further, Ms. Susanna Paasovaara has also been on a mobility visit to University of Southern Denmark (March-June 2016). This target proved to be a promising new connection considering particularly her work. The research visits have been very productive and led to expanding the scope and the impact of this project, as well as producing a number of joint publications. On the industrial side, the collaboration with Intel (Mr. Jussi Niutanen and Dr. Kerstin Johnsson) has resulted in 4 joint publications.
Overall, the multi-disciplinary and international collaboration within this project has produced remarkable results and led to multiple high-impact scientific publications as well as 3 comprehensive proof-of-concept demonstrators that are now fully ready for the market stage. These results far exceeded the original expectations of the consortium partners regarding both the volume and the impact of the research outcomes, as the published papers are rapidly gaining popularity and citations.
