Common use of SHIELD Multi-layer approach Clause in Contracts

SHIELD Multi-layer approach. The organization of the overall secure service chain architecture has been done according to three basic layers, namely the Node Layer, the Network Layer and the Middleware Layer (see Figure 2.2). This splitting is motivated by the peculiarities of the SPD solutions to be implemented namely at node (hardware and firmware), network (protocol) and middleware (software) level and by the actual industrial contest of embedded system suppliers, which are mainly organized in these three major sectors. Innovative SPD solutions will be sought at each of the above-mentioned layers, as well as in an Overlay which will be detailed later. As detailed in Section 3 of the proposal, such layering architecture is reflected in the Work Package (WP) organization. The figure also highlights that the SHIELD architecture will be conceived even to work in conjunction with legacy networks and nodes not provided with SHIELD SPD modules.
