Abstract:

Data aggregation in a wireless sensor network is an important method to reduce redundant transmission and energy consumption. Authors propose an efficient encrypted data aggregating method for wireless sensor networks, the aggregators complete the data integrity checking, source identity authentication and data aggregation without a plaintext and provide the end-to-end security for data transmission. Compared with related schemes, besides higher security,the proposed scheme makes better utilization of high redundancy of neighbor sensors' readings and reduces the communication overhead effectively.

Key words: sensor network, data aggregation, network security
