Abstract
To ensure the security of power network data,a secure encryption method for power net-work dual chaotic data under key matrix node transformation is proposed.Power network data was com-pressed 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 encryp-tion matrix,and fractional Fourier transform is applied to transform different horizontal directions,result-ing in a complex matrix for power network data encryption.The amplitude spectrum of this matrix is calcu-lated,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.关键词
