A digital image encryption algorithm based on bit-planes and an improved logistic map

Abstract

In digital image encryption (DIE) procedure centered on bit-planes and an improved arrangement map is offered by this paper. By the enhanced logistic map, a chaotic series is produced primarily and in the original image the pixels are scrambled. Further into a high and undersized 4-bit matrix, the scrambled image is divided correspondingly. To produce a chaotic series that is extremely connected with the image as the fundamental, the undersized 4-bit matrix is presented addicted to an enhanced logistic category and for location scrambling plus the XOR arrangement of the extreme 4-bit matrix and the basic is used. Lastly, to acquire the cipher text image, two fold matrices are joined into image matrix which is of 8-bit. One-time pad characteristic is the implication of this procedure. In the terminologies of the histogram, to evaluate the safekeeping of image encryption, plaintext sensitivity, data entropy, and pixel relationship index, MATLAB simulation investigates are added. Validating that the procedure compromises upright encryption, Investigational outcomes display that the number of pixel changes ratio (NPCR) is superior to Ninety percentages then the data entropy of the cipher text image extents 7.99.
