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.
