SEMOHealth

Implantable Medical Devices (IMDs) such as pacemakers, drug pumps, implantable cardioverter defibrillators (ICDs), and neurostimulators are becoming commonplace. Currently, IMDs use plain-text protocols to communicate using wireless over short-range ranges. Remote monitoring of vital health parameters over a long period of time can enable physicians to make more accurate diagnosis and provide better treatment. But those connectivity design emerges important issue of security.

The goal of this research project is to provide secure method of communication for IMDs. The high level objectives of this work is to provide: High protection of the patient data, Universal connectivity, Use of conventional mobile phones as a terminal, power efficiency, and accessibility in case of emergency.

Funesomo

Researchers from our group have been collaborating with the Networking and Security Group at International Computer Science Institute (ICSI) on the topics of network traffic analysis, security mechanisms in the Internet and fairness issues in data centers under the Funesomo project.

The key researchers involved in the network traffic analysis topic are: Vern Paxson(ICSI), Mark Allman(ICSI) and Boris Nechaev(HIIT). The main goal of the study is to analyze enterprise switch network traces collected at Lawrence Berkeley National Laboratory (LBL). Since 2008 LBL engineers performed two rounds of trace capturing. The traces were used to develop calibration techniques required to properly collect and analyze such traces. Additionally, we performed a brief analysis of TCP dynamics in enterprise environment.

Dmitriy Kupstov from our research group collaborated with Schott Shenker, Ali Ghodsi and Barath Raghavan at ICSI for the Future Internet Architecture project. The main goal of the work was to analyze security mechanism needed to protect users in the Internet from distributed denial of service attacks.

The recent cooperative work of researchers from our group, with ICSI Berkeley focuses on fairness issues in data centers. The people involved in this cooperative work are Dmitriy Kupstov, Andrey Lukyanenko, and Andrei Gurtov from Networking Research Group, HIIT and Scott Shenker and Ali Ghodsi from ICSI. This research work investigates several mechanisms that can fairly allocate network resources between tenants of the data centers. The study involves mathematical analysis (using game theory), simulations and analysis of traces collected from Facebook cluster.

FIGS

The Future Internet Graduate School (FIGS) is a new doctoral programme funded by the Academy of Finland for the period 1.1.2010-31.12.2013. Researchers from our group, Joakim Koskela, Boris Nechaev, Dmitriy Kupstov, Tatiana Polishchuk, and Ilya Nikolaevsky participate in this project.

SPEAR

The project on Secure Peer-to-peer Services Overlay Architecture (SPEAR) attempts to develop a generic mechanism to support such distributed services as P2P Session Initiation Protocol (P2PSIP). In contrast to other approaches, security is taken as the corner stone of design, integrating support for Host Identity Protocol (HIP) Based Overlay Networking Environment (HIP-BONE) into the architecture. The architecture can support various P2P services, not limited to P2PSIP, such as P2P HTTP. We envision that P2P HTTP can be used to create a community version of many useful scenarios (such as photo sharing and web caches) as plenty of current applications are based on HTTP.
