中文摘要：

在无线传感器网络的在里面网络数据聚集被显示了改进可伸缩性，延长传感器网络一生；减少计算要求。然而，起数据聚集的作用的节点将比普通节点消费更多精力；可以由于因为对解密征税令人疲乏不堪的精力预先停止使命；重新加密操作：而且，保证数据的安全将带复杂关键管理；相应钥匙。这篇论文基于隐私同形的思维在问题上面明确地被设计到地址。它能与许多更低的精力消费完成完美的安全级别平等者到一次性的垫；而且，抵抗节点俘获的攻击能被证明。用模拟；分析，我们证明我们的计划消费仅仅大约 21% AED 策划的精力。

英文摘要：

In-network data aggregation in wireless sensor network has been shown to improve scalability, prolong sensor network lifetimes and diminish computational demands. However, the node that plays the role of data aggregation will consume much more energy than common nodes and may quit the mission in advance due to energy exhausting because of taxing decryption and re-encryption operation; moreover, it will bring complex key management to ensure the security of the data and corresponding keys. This paper was designed specifically to address above problem based on the thought of privacy homomorphism, It can achieve the perfect security level equal to one-time pad with much lower energy consumption; moreover, it can be proved to resist the attack of node capture. Using the simulation and analysis, we show that our scheme consume the energy only about 21% of AED scheme.
