摘要
针对无线传感网(Wireless Sensor Network,WSN)传递信息过程中容易被外界入侵,致使信息泄露和WSN损坏的问题,通过节点标识密钥预分配加入时间戳的方法,以降低节点的计算和通信开销为前提基础上,提出了在数字水印中对时间戳的提取过程与嵌入过程的使用,利用无线单片机CC2430/CC2431具备集成CC2420RF无线射频收发器的特性进行仿真测试和检测,验证并实现了安全又节能的密钥预分配系统。
To solve the problem that the Wireless Sensor Network(WSN)is easily invaded by the outside world in the process of transmitting information,resulting in information leakage and damage to the WSN,the method of adding timestamps by pre-distribution of node identification keys is based on the premise of reducing the calculation and communication overhead of nodes.The use of the extraction process and embedding process of timestamps in digital watermarking is proposed,and the simulation test and detection are carried out by using the characteristics of the wireless microcontroller CC2430/CC2431 with integrated CC2420RF wireless radio frequency transceiver.A secure and energy-efficient key pre-distribution system is verified and implemented.
