Energy efficient secure data aggregation framework in wireless networks

This paper constructs an energy efficient secure data aggregation framework for wireless networks, especially for wireless sensor networks with femtocells. We propose the Leaf Node Representation (LNR) scheme and the Hop-by-hop MAC Authentication (HMA) scheme, in order to provide a balance between the security and the communication cost. The ideas in this paper are not restricted to wireless sensor network, it can be used in other kind of wireless network after modification. Under the proposed scheme, keystream-based encrypted data aggregation is feasible and practical for large scale implementations. Analytical results show that the proposed scheme can reduce the communication overhead significantly compared to existing approaches.
