针对无线传感器网络中数据的真实性识别问题,提出了一种基于数字水印技术的无线传感器网络数据识别传输方案.为了区分正常数据包与异常数据包,定义了数字基因构造方法.利用待发送数据自身特征构造数字基因,设计了水印嵌入和检测算法,将数字基因作为数字水印嵌入到待发送数据中,实现无线传感器网络中传输数据的真实性识别.仿真实验表明,该方案能够有效地识别出注入、重放和随意修改的数据包,实现无线传感器网络中数据的有效传输.
Aiming at the problem of authenticity identification of data in wireless sensor networks, a data watermarking scheme based on digital watermarking technology is proposed in this paper.In order to distinguish between normal data packets and abnormal data packets, a digital gene construction method is defined.Using the data to be transmitted The digital gene is designed and embedded into the data to be sent as a digital watermark to realize the authenticity identification of the transmitted data in the wireless sensor network.The simulation results show that this scheme can effectively identify Injected, replayed and arbitrarily modified data packets, the wireless sensor network to achieve effective data transmission.
