基于可逆数字水印认证的无线传感网数据融合协议
Reversible digital watermarking-based protocol for data integrity in wireless sensor network
摘要
Abstract
For the contradiction between high energy consumption of WSN privacy protection algorithm and constrained resources of sensor network, a recoverable data fusion protocol that ensures data integrity and confidentiality based on reversible digital watermarking and homomorphic encryption technology was proposed. On the one hand, the data from the sensor was embedded by the difference expansion method by using the reversible digital watermarking technique, and original data could be recovered by using a reversible watermark to ensure the integrity check of the fusion data when the fusion data were destroyed. On the other hand, elliptic curve homomorphic encryption encrypted data to prevent sensor data from being perceived during data transmission. Security results show that the proposed protocol performs well against cluster head node compromise as well as tampering from an attack. Performance analysis shows that the protocol has significant advantages over other algorithms in terms of computation, communication overhead and propagation de-lay. The experimental results show that the protocol has a low resource overhead and improves network performance.关键词
