A Digital Image Scrambling Algorithm Based On Chaotic Sequences
Zhao Yu-xia · Journal of Shangluo University · 2009
Based on chaotic sequences,a new digital image scrambling algorithm is presented.XOR scrambling algorithm based on Logistic mapping and Hybird mapping is used to scramble the image,odd-numbered lines XOR two value sequences produces with the Logistic mapping,and the even-numbered line XOR the Hybird mapping produces two value sequences.The simulating experimentation shows that the algorithm is simple,security very highly,and has certain anti-aggressivity to the salt pepper noise and shears.
