Abstract In order to improve the security of secret image transmission, using
the property of the chaotic sequence in the encryption algorithm, a
block image encryption scheme based on Logistic and Henon composite
chaotic system is presented. The image encryption algorithm from two
aspects that the pixel grayscale value and pixel position through
two different chaotic sequences transform of the Logistic and Henon.
At first, Logistic chaotic sequence is applied to the scrambling
operation on the pixel position matrix. Then the pixel values of
blocked images are scrambled based on Henon chaotic sequence. The
experiments show that the algorithm has good encryption effect, and
has better robustness to crop or noise attack. The cross correlation
of encrypted image are decreased and the transport security is
improved, the result shows that the project is effective.
