Abstract

The proliferation of sensor networks provides a promising solution for a variety of ubiquitous data services, but it challenges the data security and privacy because of its unfavorable deployment nature of being prone to physical attacks with circumscribed source available. Considering the data redundancy, energy constraint, and security requirement, this paper proposed a secure data aggregation scheme which supports end-to-end encryption using privacy homomorphism as well as hop-by-hop verification using ECC based MAC in cluster based sensor networks. The analytic comparing results show that our scheme has higher resistance against eavesdropping and fabricating attacks at a little additional computational cost with higher connectivity.
