The overall goal of this research project is to improve both the security level and the security awareness when developing, installing, and using (open source) VoIP/PBX/multimedia solutions.
The project is anchored in the newly formed EUX 2010 network where researchers (from the Nordic countries) regularly meet representatives from Nordic (probably extended to other European countries in near future) open source PBX/VoIP developers, integrators and deployers, consultants, support organizations, and (future) customers. The aim of EUX 2010 is to develop, in the coming years, an open integrated communication platform for voice and video communication giving government organisations and larger corporations a better communication infrastructure and a more efficient use of time and effort.
We improve the security of VoIP systems by building a security testbed, preparing security models for various scenarios, and by performing security protocol verification.
Benefit for customers
Increased security, quality and stability in VoIP infrastructures.
Benefit for society
A more secure, stable VoIP infrastructure with highly knowledable vendors and service providers.
