Image encryption algorithm based on m-sequence integer modulation and image scrambling
Jiasheng Liu, Xianwu Huang · Journal of Computer Applications · 2007
After analyzing the m-sequence generating principle,a new image position scrambling method named m-sequence transform and a new image value of pixels substitution method named m-sequence integer modulation were presented respectively.Encrypted effect of m-sequence transform was also studied.And based on those,a practical image encryption algorithm was put forward according to the characteristics of chaotic images.Then key spaces and security of the proposed algorithm were analyzed.Finally,the experimental results using this algorithm were shown in this paper.
