Work package 0: Architecture
The objective of the architecture workpackage is to identify the overall
WSN network architecture and to provide a threat analysis derived from
the scenario space and such a WSN architecture. It deals with:
Carefully analysing and understanding the security requirements, as well
as the network and energy-efficiency requirements are mandatory
pre-requisites for the subsequently described technical core
workpackages will identify security requirements and energy requirements
for the specific WSN applications.
The architecture and device specification will go in line with the
scenario definition. This task provides a WSN architecture and a
reference device description.
Threat analysis and attacker model
Starting from an extended Dolev-Yao threat model and considering the
device architecture and the network architecture we will provide a
careful threat analysis. This takes into account the various attacker
models which may vary for the different WSN scenarios. Also, the
specific WSN traffic patterns will be considered for the treat analysis
and the attacker model.
The scenarios agriculture, road service and homeland security serve as a
basis to identify a subset of reference WSN scenarios which we will
consider more deeply within the project. A major metric for the final
scenario choice and definition will be their relevance to cover a broad
spectrum of security and reliability aspects of the envisioned modular
WSN security toolbox.
