Abstract
P2P networks are being successfully deployed and used for almost a decade. Until recently mainly used on the margin, they are now aiming at entering general digital network media market. Next generation P2P networks promise low cost content distribution platform and advanced interactive features. They could enable a number of shifts in the market like from classical linear TV to non-linear, on-demand, anytime-anywhere, by anyone. They tend to unlock end user publishing potential and shift from popular content to disclosure of "long-tail" content. Not only researchers and the end users are interested in this promising technology but also professional content providers, advertiser, broadcasters, artists, various service providers and collecting societies. One of the most promising technology in the field is based on BitTorrent protocol. To enable the technology shift to new generation, the protocol is being extended with various new features.
The new generation P2P network approaches based on BitTorrent protocol seriously lack security features needed to enter general digital network media market. For this reason the project's primary objective is security of new generation P2P networks. The project will design and implement needed security services for secure system operation. Security issues that are most critical for provisioning in new generation networks are professional content providers services compliance with current security related international standardization recommendations, privacy preserving user-centric identity management, core security services for content delivery platform and feature extensions, and trust establishing mechanisms for secure user involvement in mostly anonymous environment. Developed security solutions will be validated in real, service oriented environment with real users.
Significance for science
Security and privacy are crucial elements of modern information and communication systems, such as new generations of P2P networks and the new e-services being developed under the EU Directive for e-services recently adopted by EU Parliament. Security and privacy provisioning is much harder in complex networks due to distributed and decentralized nature of the network systems. The project's primary objective was security services and solutions provisioning in new generation P2P networks. The project has filled several scientific gaps in this area and improved security provision in the networks. The developed Enhanced Closed Swarm Protocol (ECS) answered to one of the most important professional content providers’ requirements, i.e. how to protect the P2P content delivery from unauthorized usage. The protocol enhancements provide additional flexibility in the access control mechanism, enabling fine grained security policies specification and enforcement. Moreover, they enable efficient and flexible content delivery in various scenarios. In the area of trust and reputation management, the systemic features of on-line trust were determined and a framework of design properties based on the principles of general systems theory was introduced. This work represents the first attempt of fundamental social science principles from general systems theory to be applied on pure technical on-line solutions. The created multidimensional framework is intended to guide the researchers and developers in the design-process of on-line trust and reputations systems, and to help them assessing their completeness and consistency. On the other hand, the novel conceptual model of security context defines higher level security context abstractions that are meaningful for security relevant decisions in diverse use cases of many internet social network based systems, not just in P2P networks. The model clarifies and complements the notion of security context and enables specification of security policies that will guide security relevant system adaptation upon context changes. The developed approach will facilitate specification, management and reuse of security policies for various types of internet networks and systems.
Significance for the country
Internet of content and knowledge is one of the main vectors of growth of the Future Internet. It is expected that digital content will not only increase in number in the near future, but also in size, due to increases in resolution, the ease of creation and manipulation, and growth of the number of users and devices supporting the users’ needs. Next generation P2P networks hold the promise to become the most important digital content distribution technology. Both free and commercial content will be delivered via this environment that will also be based on users’ personal data in order to support personalized services. This is why security and privacy are so important in those networks. The project results increase security level of a content distribution infrastructure based on the next generation of P2P networks. Various actors of the media distribution value chain in Slovenia can benefit from them: • Content owners and providers can enlarge their markets and can make more profits. • For broadcasters, a secure P2P network can represent yet another outlet for distributing their programmes and contents. • Network providers can benefit as the overall network load is reduced. • Security experts and system developers will benefit from the developed generalized trust and reputation mechanisms and other security mechanisms. • End users will more securely participate in the content distribution. The project results have been introduced into Slovenian Higher Education system through undergraduate and graduate programmes of the Jozef Stefan International Postgraduate School where members of the project team are teaching. So far, research activities for two doctoral theses, which will be defended in the first half of 2014, one M.Sc. thesis and one diploma thesis have been conducted. The results have also contributed to more successful participation of the project team members at the EU calls in the field of information security. Newly obtained research projects will ensure that Slovenia stays in touch with the latest European security research activities, which are crucial for the Information society. It should be mentioned here the recent Directive on Network and Information Security (NIS) adopted by the EU Parliament that focuses on the NIS platform as the basic strategy for the next four years of development of the single digital market in EU.
