Description
The project aims to study and develop an end-to-end secure infrastructure for delivery of collaborative multimedia services over integrated satellite terrestrial networks. The project envisages an expedient combination of broadcast and unicast technologies where typically the main component is satellite broadcast/multicast assisting in-network caching telecommunication systems.
Targeted Improvements:
Collaborativeservices delivery over heterogeneous integrated satellite terrestrial networks creates new business opportunities for satellite networks enabling satellite service providers to enhance their services line up. Users can benefit from an enhanced service experience,i.e. service resilience and security and improved Quality of Experience.
Description:
The activity shall analyse integrated networks deployment scenarios where the satellite acts as the interconnection link between in-network caches and/or feeds edge-network caches at micro-centre locations. Video packet or chunk based caching techniques shall be analysed. Cache access control, content integrity, provenance, confidentiality and authentication as well as privacy and caches security and availability are of outmost importance. Once the security requirements are established, the activity shall focus on the security solutions proposed for distributed in-network caches in terrestrial networks, and examine how these solutions compare to traditional IP-based security solutions, what are the benefits they bring and how they could be adapted to match satellite network requirements. The new security solution space shall include advanced solutions against privacy infringement attacks, enhancements of access control and the establishment of security custodian as a new trustful entity, and use of homomorphic encryption.
The activity shall analyze carefully the complexity of proposed security solutions and minimize the signalling exchanges over satellite links. The activity shall then extend the integrated satellite terrestrial networks architecture with selected security mechanisms, validating the security-enhanced architecture performance. The activity shall analyze also how the value chain configurations are impacted by the introduction of security and content rights management enablers, identify potential conflicts between actors and propose solutions. The activity shall build upon the results of the ARTES 5.1 activity on âThe role of satellite in adaptive bitrate streaming servicesâ by using and enhancing the developed Proof-of-Concept with security and content rights management solutions.
