Wireless Sensor Networks (WSN)s are an exciting development with very large potential to have a significant beneficial impact on every aspect of our lives while generating huge opportunities for European industry. What is needed to kick off the development and exploitation of WSNs is an architecture for medium and large scale wireless sensor networks integrating comprehensive security capabilities right form the concept stage. This would support the rapid development of sensor networks and would open up the application domain for commercial activities. UbiSec&Sens intends to solve this by providing a comprehensive architecture for medium and large scale wireless sensor networks with the full level of security that will make them trusted and secure for all applications. In addition UbiSec&Sens will provide a complete tool box of security aware components which, together with the UbiSec&Sens radically new design cycle for secure sensor networks, will enable the rapid development of trusted sensor network applications. The UbiSec&Sens approach is to use three representative WSN scenarios
to iteratively determine solutions for the key WSN issues o scalability, security, reliability, self-healing and robustness. This will also give a clearer understanding of the real-world WSN requirements and limitations as well as identifying how to achieve a successful rollout of WSNs.

NEC is technically leading the project with focus on probabilistic security for WSNs.
