A Secure Encryption Method for Double Chaos Data in Power Networks Under Key Matrix Node Transformation

  • 摘要: 为保障电力网络数据安全,提出一种密钥矩阵节点变换下的电力网络双混沌数据安全加密方法。将电力网络数据无损压缩,使用Logistic映射方法和Henono映射方法,生成3个电力网络混沌数据序列,将该序列输入到密钥矩阵,经节点变换,得到数据置换矩阵,再将矩阵与初始加密矩阵相乘后,采用分数傅里叶变换方式在不同水平方向、垂直方向进行变换,得到电力网络数据加密的复数矩阵,计算该矩阵幅度谱,将其由频域转换到空间域,从而完成一次电力数据加密,重复该过程实现二次加密。实验结果表明:该方法可实现电力网络数据无损压缩,并能有效加密图像类和字符类的电力网络数据。

     

    Abstract: To ensure the security of power network data, a secure encryption method for power network dual chaotic data under key matrix node transformation is proposed. Power network data was compressed without loss. Logistic mapping method and Henono mapping method are employed to generate three chaotic power network data sequences. The sequence is the initial encryption matrix.The matrix nodes are transformed to obtain the data permutation matrix. This matrix is then multiplied with the initial encryption matrix, and fractional Fourier transform is applied to transform different horizontal directions, resulting in a complex matrix for power network data encryption. The amplitude spectrum of this matrix is calculated, and it is converted from the frequency domain to the spatial domain to complete the first power data encryption. This process is repeated to achieve the second encryption.The experimental results show that this method can achieve lossless compression of power network data and effectively encrypt image and character power network data, with good application effects.
