A common approach to overcome the limited nature of sensor networks is to aggregate data
at intermediate nodes. A challenging issue in this context is to guarantee end-to-end security …

Sensor networks promise viable solutions to many monitoring problems. However, the
practical deployment of sensor networks faces many challenges imposed by real-world …

Achieving security in resource-constrained wireless sensor networks is a challenging
research task. Many key management schemes have been developed recently to provide …

Efficiency and security are two basic requirements for sensor network design. However,
these requirements could be sharply contrary to each other in some scenarios. For example …

Many sensor networks (SN) use in-network aggregation to minimize the amount of data
transmitted by sensors. Unfortunately, aggregation makes the network more vulnerable: a …

Data aggregation in wireless sensor networks (WSN) is a rapidly emerging research area. It
can greatly help conserve the scarce energy resources by eliminating redundant data thus …

Wireless Sensor Networks (WSNs) rely on in-network aggregation for efficiency, however,
this comes at a price: A single adversary can severely influence the outcome by contributing …

In many Wireless Sensor Networks (WSNs), providing end to end secure communications
between sensors and the sink is important for secure network management. While there …

Aggregation schemes for reducing transmission cost have been proposed for wireless
sensor networks for a long time. Aggregated results can be easily altered by adversaries …

This paper studies security for data aggregation in sensor networks. Current aggregation
schemes were designed without security in mind and there are easy attacks against them …
