A New Image Encryption Algorithm Based on Chaotic Maps
Qiuhui Li, Gongbin Qian · 2017
This paper presents an image encryption algorithm based on Logistic map and Henon map. The main idea is that the original image is randomly cut into blocks with four different sizes. Each block is randomly XORed with Logistic map or Henon map according to the cutting parameters and thus the pixel values of each block image are altered. After that, these images are stitched into an encrypted image by different cutting direction. The encrypted image has the same size as the original image. The analysis of the encryption and decryption algorithm shows that the algorithm has a good encryption effect, anti-attack ability and high security.
