چكيده فارسي :
Wireless sensor networks are composed of sensors
with low computational and energy resources. Transmission of
data is one of the most energy consuming operations in such
networks. In-network data aggregation is a popular technique
which is performed to reduce data transmissions. However, by
aggregating multiple data into one, the security of them is no
longer guaranteed. While concealed data aggregation methods
have been recently proposed to provide energy efficient, end-toend
confidentiality, not much work has been done to enhance
them with aggregate integrity. In this work, we propose a
scalable and energy efficient bihomomorphic method to preserve
end-to-end confidentiality and aggregate integrity against
outsider attacks. A distributed validation scheme is used to
prevent blind rejection caused by outsiders. To provide better
resilience, a key refreshment method is used to prevent analysis
attacks.
