Abstract

Today’s research on image in internet, security of images and videos became an important problem. This manuscript designs an image encryption algorithm. We recommend a new image secured algorithm using a large pseudorandom permutation which is combinatorial generated from small permutation matrices based on chaotic maps. We are using longer pseudorandom bits for encryptions. The random-like nature of chaos is effectively spread into encrypted images by using the permutation matrix. This shows that the proposed encryption scheme provides comparable security with that of the conventional image encryption schemes based on Baker map or Logistic map.
