SAT2 - Semantic and Ambient Trust Technologies
The SAT2 (Semantic and Ambient Trust Technologies) project, headed by Safelayer and carried out in collaboration with the Universitat Oberta de Catalunya and the Complutense University of Madrid, forms part of the industrial research required to build the Future Internet. A task that involves defining and creating advanced trust and security services that take into account the future networks, especially ad-hoc networks, so they can be adapted to the individual characteristics of the network context and the user to make them more specific and user friendly.
The first phase of the SAT2 project was divided into three main lines of investigation: defining ontologies for describing ambient information, adapting ontologies for managing trust services and making advances in the areas of auto-configuration, collaborative mechanisms and privacy in ad hoc networks.
In the second phase of the project, a semantic ambient trust platform prototype was validated and a context-stamping service was designed. The auto-configuration scheme for mobile ad hoc networks and the proposed collaborative algorithms for ad hoc networks were also validated.
The tasks currently being developed include:
- Improving the auto-configuration protocol for ad hoc networks.
- Incorporating security in the current proposals for mesh network auto-configuration.
- Resolving the security challenges posed by the use of cognitive radio networks.
- The Future Internet: developing system architecture and infrastructure based on future networks (ad hoc, mesh, etc.), ambient intelligence and semantic services.
- Studying application and use cases that can be easily resolved with maximum security and trust using this type of architecture.
- Validating components of the semantic ambient trust platform through the use semantic technologies (RDF), XML, Web services and SOA.
The Spanish Ministry of Industry, Tourism and Trade (Ministerio de Industria, Turismo y Comercio) has co-funded this work over several years through the Plan AVANZA I+D programme and other projects (refs. FIT-360000-2007-48, TSI-020100-2008-365 and TSI-020100-2009-374).
