TECHNOLOGY<br />
pSHIELD will involve collaboration<br />
between various European<br />
companies and<br />
research centres grouped in<br />
a consortium, in which Finmeccanica<br />
plays a significant<br />
role because of the<br />
involvement of several<br />
Group companies, and <strong>Elsag</strong><br />
<strong>Datamat</strong> in particular, which<br />
is in charge of the technical<br />
management of the project.<br />
THE SHIELD FRAMEWORK<br />
ARCHITECTURE<br />
This project is the first stage<br />
in more extensive research<br />
work to develop and validate<br />
SHIELD, a framework<br />
architecture that aims to act<br />
as a point of reference outside<br />
the applications arena<br />
for the security of embedded<br />
systems at European<br />
and international level. In<br />
order to encourage the reduction<br />
of design costs and<br />
time-to-market, SHIELD<br />
adopts a model that is open,<br />
modular and scalable, laying<br />
the foundations for the<br />
qualification of the dependability<br />
and security guarantees<br />
of embedded systems.<br />
The use of an overlay type<br />
approach to SPD functionality<br />
and the introduction of<br />
semantic technology provide<br />
a good response to the<br />
complexity associated with<br />
the design, development<br />
and realisation of native<br />
SPD in embedded systems.<br />
Using semantics, existing<br />
technologies available can<br />
be automatically arranged<br />
to satisfy the needs and levels<br />
of security, privacy and<br />
dependability required by<br />
PSHIELD FUNCTIONAL ARCHITECTURE<br />
ternazionale. Al fine <strong>di</strong> favorire la riduzione dei costi <strong>di</strong> progettazione<br />
e il “time-to-market”, SHIELD adotta un modello<br />
aperto, componibile ed espan<strong>di</strong>bile e pone le basi per i processi<br />
<strong>di</strong> qualificazione degli apparati embedded in termini <strong>di</strong><br />
affidabilità e garanzie sulla sicurezza.<br />
L’utilizzo <strong>di</strong> un approccio <strong>di</strong> tipo “overlay” alle funzionalità SPD<br />
e l’introduzione <strong>di</strong> tecnologie semantiche riescono a in<strong>di</strong>rizzare<br />
bene la complessità associata alla progettazione, allo sviluppo<br />
e alla realizzazione <strong>di</strong> una SPD nativa nei sistemi<br />
embedded.<br />
Usando la semantica, le tecnologie <strong>di</strong>sponibili possono essere<br />
automaticamente composte per combaciare con le necessità<br />
e con i livelli <strong>di</strong> sicurezza, privacy e affidabilità richiesti dalle<br />
applicazioni, consentendo una riduzione dello sforzo <strong>di</strong> pro-<br />
gettazione, messa in opera e manutenzione delle singole tecnologie.<br />
L’approccio SHIELD è basato sulla modularità e<br />
sull’espan<strong>di</strong>bilità e può essere adottato per introdurre soluzioni<br />
<strong>di</strong> SPD native nell’ambito <strong>di</strong> vari settori (tra cui, ad esempio,<br />
i trasporti, le comunicazioni, la salute e l’energia).<br />
OBIETTIVI DI PSHIELD<br />
Il concetto guida <strong>di</strong> pSHIELD è <strong>di</strong>mostrare la componibilità<br />
delle tecnologie per garantire sicurezza, privacy e affidabilità<br />
consolidando le soluzioni esistenti e sviluppando, qualora sia<br />
necessario, funzionalità aggiuntive.<br />
28<br />
applications, reducing the<br />
effort needed to design, implement<br />
and maintain in<strong>di</strong>vidual<br />
technologies. The<br />
SHIELD approach is based<br />
on modularity and scalability<br />
and can be used to introduce<br />
native SPD solutions in<br />
various sectors (inclu<strong>di</strong>ng,<br />
for example, transport, communications,<br />
health and energy).<br />
GOALS OF PSHIELD<br />
The main aim of pSHIELD is<br />
to demonstrate the modularity<br />
of security, privacy and<br />
dependability technologies,<br />
consolidating existing solutions<br />
and developing ad<strong>di</strong>tional<br />
functions where<br />
necessary.<br />
The pSHIELD approach to<br />
SPD will be on four <strong>di</strong>fferent<br />
levels: node, network, middleware<br />
and overlay. For<br />
each of these, the state of<br />
the art of in<strong>di</strong>vidual technologies<br />
and solutions will<br />
be improved, with the integration<br />
of hardware and<br />
software communication<br />
systems, cryptography, middleware<br />
and applications.<br />
Security, privacy and dependability<br />
technology will<br />
be supplemented with the<br />
new function “modularity”,<br />
to provide adaptability with<br />
the SHIELD framework.<br />
To verify the achievement of<br />
these important milestones,<br />
the pSHIELD project will validate<br />
the integrated SHIELD<br />
in various application scenarios,<br />
inclu<strong>di</strong>ng the monitoring<br />
of railway cars for<br />
hazardous goods transport.
