In-network data aggregation is essential for wireless sensor networks where energy resources are limited. In a previously proposed data dissemination scheme (directed diffusion wi...
Designing message integrity schemes for data aggregation is an imperative problem for securing wireless sensor networks. In this paper, we propose three secure aggregation schemes ...
Abstract-- Wireless Sensor Networks (WSNs) rely on innetwork aggregation for efficiency, however, this comes at a price: A single adversary can severely influence the outcome by co...
