高效安全的无线传感器网络数据聚合方案

Efficient and secure data aggregation scheme for wireless sensor networks

提出了一种高效安全的无线传感器网络数据聚合方案。节点数据用对称密钥进行加密,远端服务器解密数据,聚合头在不需明文的情况下完成完整性检查、发送方身份认证及数据聚合等操作,保证了安全的端到端数据传输。分析与仿真表明,与相关方案相比,该方案可有效抵抗多种恶意攻击,提供了较高的安全性及较小的能耗开销。

Secure end-to-end data transmission is an important method to protect the data privacy in Wireless Sensor Networks （WSN）. Authors proposed an efficient and secure data aggregation scheme for WSN. Sensor readings were encrypted with symmetric key and the decryption of cipher-text was performed by remote server, the aggregators completed the operations such as data integrity verification, sender identity authentication and data aggregation without the plaintext of sensor readings. Analysis and simulation show that the proposed scheme can resist various malicious attacks effectively, provides higher security and lower energy consumption than related schemes.
