Data Aggregation Scheme for WSN with Privacy Protection

Data aggregation is an important method to reduce redundant transmissions in wireless sensor networks (WSNs). Authors proposed a secure data aggregation scheme for WSNs based on one-way function. The aggregators completed data aggregation, identity authentication and integrity checking without decrypting the cipher-text and ensured the privacy of transmitted data. Compared with related scheme, the proposed scheme has higher security in terms of resilient against active attack, node compromise attack and reduces the energy consumption effectively.
