Ubiquitous Networks with a Secure Provision of Services, Access, and Content Delivery

Project Overview: 

UBISEC aims at an advanced infrastructure for large-scale mobility and security based on SmartCard technologies for context-aware and personalised authorisation and authentication services in heterogeneous networks. This requires advanced personalisation and localisation technologies with high security in order to keep privacy and to protect computing devices, their software components, and personal user data including user profiles. The project does not deal with the development of a complete framework, but focuses primarily on the following areas: Security, Customisation, Core technology and Service Discovery.

NICS’ role in UBISEC mainly focused on Security-related topics. NICS has been responsible on the extensibility of current PKI concepts in ubiquitous networks. This means not only to adapt protocols and processes to the new scenarios, but to adapt digital signatures and authentication procedures to the collection of new devices that will form part of ubiquitous networks. Similarly, and because authorisation services are specially relevant in these new scenarios, NICS contributed by improving actual Privilege Management Technology, up to a level in which the technology is widely available to citizens and companies. In this area NICS helped to deploy the Privilege Verifier (PV). NICS focused on how profiles must be syntactically built and semantically interpreted. At the same time, NICS worked on the design of an infrastructure for the automatic customisation of devices and services through context-aware profile processing, which is of capital importance for mobile applications [1].

NICS also designed, implemented and tested a Mobile DRM framework with non-repudiation services in ubiquitous scenarios [2].

Security is a core issue in all designs.
