针对信息抗截获过程中,由于数据节点控制能力较弱,导致数据易丢失与信息安全性不高的问题,文章提出了基于混沌映射的光纤通信物理层抗截获方法。通过光纤信号检测识别判定截获信号的存在性,基于混沌映射加密图像,构建密文矩阵;物理层通信编码联合传输,实现接收端和发送端的信息交换;建立通信物理层抗截获模型,实现光纤通信物理层抗截获目标。在搭建的光纤通信网络结构中,选择一组带有实际意义的图像作为测试样本,分别采用所提方法和传统方法做对比,实验结果表明,在所提方法下能够对图像数据进行全方位加密,具有较强的抗截获性能,且在图像传输中能够保留图像中的数据信息,而传统方法分别丢失了15和12组数据信息,验证了所提方法更具有优势。
In the process of anti-interception of information
due to the weak control ability of data nodes
data is easily lost and information security is not high. An anti-interception method of optical fiber communication physical layer based on chaotic mapping is studied. The existence of the intercepted signal is determined by optical fiber signal detection and identification
and the ciphertext matrix is constructed based on the chaotic map encrypted image. The physical layer communication code is jointly transmitted to realize the information exchange between the receiver side and the transmitter side. We establish the anti-interception model of the communication physical layer to achieve the goal of anti-interception of the optical fiber communication physical layer. In the constructure of optical fiber communication network
a set of images with practical significance are selected as test samples. The proposed method and the traditional method are used for comparison. The experimental results show that the image data can be fully encrypted based on the proposed method. It has strong anti-interception performance
and the data information in the image can be retained in the image transmission
However
the traditional method loses 15 groups and 12 groups respectively
indicating that the proposed method has better performances.
