安全透明的无线传感器网络数据汇聚方案

Secure and transparent data aggregation for wireless sensor networks

提出了一种安全透明的传感器网络数据汇聚方案,汇聚节点在不对加密数据进行解密的情况下通过散列函数与异或操作完成数据完整性检查、数据源身份认证、数据汇聚等功能,保证了数据在汇聚及传输过程中的隐私性。与相关数据汇聚方案相比,除了提供密钥安全性,所提方案可有效抵抗主动攻击、节点妥协攻击及DoS攻击等恶意行为,具有高的安全性;同时,方案的汇聚结果提供了数据的全局分布信息。

A secure and transparent data aggregation scheme for wireless sensor networks was proposed. Using hash func- tion and XOR operation, the aggregation node completed the data integrity checking, source identity authentication and data aggregation without decrypting the encrypted data, ensured the data privacy in the process of transmitting and ag- gregation. Compared with related data aggregation schemes, except providing high security of encrypt key, the proposed scheme had better performances in resilient against active attack, node compromise attack and DoS attack. Also, the pro- posed scheme provides the information of the global data distribution.
