Abstract: Systems involving wireless sensor networks usually have two main assets, namely the sensor data in transit over the network, and hardware nodes. Traditional security approaches protect these assets by physical means and resource-consuming software like firewall or intrusion detection sub-systems. These are no longer applicable "as-is" in wireless sensor networks, where resources are severely constrained and nodes are physically assumed vulnerable. In addition, the applications of wireless sensor network technologies refer to less than a dozen to more than a thousand nodes, depending on application requirements. This indicates a need to shift the traditional view on security from the perspective of strong individuals to one that relies on the correlation and cooperation of weak individuals.
In this presentation, I will introduce wireless network technologies, review their security issues, and present state-of-the-art achievements, along with their limitations. This description of the current landscape of security will show the potential for decentralized approaches, leveraging the number of nodes instead of their individual capabilities. I will finally present our approach at , focusing on our activities related to decentralized key management and secure routing.
Speaker: Eric Platon is a visiting researcher at , funded by . He holds a joint Ph.D. in Computer Science from and for work on exception management in multi-agent systems. His research interests pertain to security, self-adaptive programs, and exception handling in mobile systems, notably wireless ad hoc networks of sensors. He is involved as a software architect in the XAC project, a government-funded research project for secure and self-adaptive applications in embedded systems.
