Wireless sensor networks have a wide spectrum of civil and military application that call for security. In-network data aggregation has been shown to improve scalability, prolong sensor network lifetimes and diminish computational demands. However, aggregator in the network that play the role of the data aggregation will consume much more energy than common nodes and will quit the mission in advance due to energy exhausting because it must decrypt the data first and re-encrypt them after aggregating the data, moreover, it will bring complex key management to ensure the security of corresponding keys. Our scheme was designed specifically to address above problems, cluster head can aggregate the encrypted data without decrypting first and re-encrypting. Our scheme can achieve the security equal to one-time pad; moreover, combined with the mechanism of dynamic cluster head recycling, this protocol can balance energy consumption of the whole network and prolong its life. Furthermore, this scheme can resist the attack of node capture, improves the survivability of network. Through simulation, we show that our scheme can save about 3-5 times energy consumption than basic scheme according to different density of network and average hops from node to base station.
