Digital Image Encryption Algorithm of Tujia Brocade Design by Double Chaos

    Graphical Abstract
    • Abstract
  • We discusse the digital image encryption algorithm on Tujia brocade by chaos sequence theory.Firstly,the origin image is transformed by discrete wavelet transformation(DWT),and the odd-line of the changed matrix operated with binary sequences of Logistic mapping by xor operation,and its even-line operated with binary sequences of Hybrid mapping.Then,the new encryption image is transformed by inverse discrete wavelet transformation(IDWT).The experimental results show that the algorithm is more safety and better encrypted effect.
