Secure In-Network Processing in Sensor Networks
Tassos D. Dimitriou, Ioannis Krontiris · Auerbach Publications eBooks · 2006
In-network processing in large-scale sensor networks has been shown to improve scalability, eliminate information redundancy and increase the lifetime of the network. In this chapter we address the challenge of securing innetwork processing, both for aggregating sensor node’s measurements and disseminating commands from the aggregators to individual sensor nodes. We present the key mechanisms for establishing a secure communication channel between sensor nodes and aggregators and show how scalability and resiliency against different type of attacks can be achieved. We also present how requirements such as dynamically adding new nodes in the network and harmonious existence with other security protocols of the network can be met. Finally we elaborate on resilient aggregation under corrupted measurements and the proposed solutions. 1 2
