OSIRIS

Protection of Digital Twin Infrastructures in B5G/6G Networks

  • ITEA - Information Technology for European Advancement and co-funded by the Spanish Ministry of Industry(FIT-340000-2005-248 and FIT-3400005-2007-36)
  • Duration: 01/01/2005 to 31/12/2008
Project Overview: 

OSIRIS (Open Source Infrastructure for Run-time Integration of Services) is an EU-project funded under the ITEA/EUREKA umbrella, co-funded by the Spanish Ministry of Industry.

OSIRIS aims to integrate technologies developed in Service-Oriented Architectures (SOA) and asynchronous middleware with the goal to provide a flexible open source infrastructure for run-time integration of services. OSIRIS supports the integration of different platforms, services and devices to build added-value services. OSIRIS is an across-domain open source service platform that will provide support for services provisioning, aggregation, delivery, dynamic adaptation to the context and lifecycle management.

Under the scope of OSIRIS, NICS has designed and implemented an advanced authorization and delegation infrastructures to cover the security requirements of OSIRIS Architecture [1][2]. Between others developments in the proyect, NICS desinged Weighted Trust Graphs (WTG). WTG is a formalism that allows authorization and delegation relationships to be modelled.One of the mayor advantages of WTG is that it allows users to define more complex policies and provides a graphical representation for them. Another difference from previous proposals is that in WTG, delegation statements are defined separately from authorization ones, so a delegation credential does not implicitly give authorization rights [3].

Moreover, we simulate an authorization and delegation system using knowledge based technology. This proposal is part of a visual tool that is intended to be an implementation of the theoretical model weighted trust graph (WTG) [4].
