摘要: DF数据聚合方案在加/解密时采用相同的秘钥,因此不能有效抵抗已知明文攻击、捕获攻击及中间人攻击。为解决该问题,提出一个适用于无线传感器网络的数据聚合方案。该方案利用一次一密的双重加密机制,多资源节点在加/解密时采用不同的密钥,从而有效抵抗明/密文攻击、捕获攻击以及中间人攻击。同时,基于隐私同态技术进行数据加密,使得聚合数据时无需解密,保证了数据机密性和用户的隐私性。分析结果表明,与SDAP和SEDA方案相比,该方案具有较强的前向安全性和较低的存储开销。

Abstract: There is only a same key in Domingo-Ferrer(DF) data aggregation scheme while encryption/decryption,therefore it can not resist the known plaintext attack,capture attack,etc.In order to solve these problems,this paper proposes a data aggregation scheme based on Privacy Homomorphism(PH) mechanism.The scheme adopts a double encryption mechanism of one-time pad,multi-resource node uses different key while encryption/decryption,so that it can be effectively against plaintext/ciphertext attack,compromising attack and man-in-middle attack.It does not decrypt while aggregating,so need not the extra decryption overhead,and at the same time it ensures the confidentiality of the data and user’s privacy.Analysis result shows that this scheme has strong forward security and lower storage cost compared with the SDAP and SEDA scheme.

Key words: aggregation, cluster, compromised attack, Privacy Homomorphism(PH), aggregator
