Image Encryption Using Spined Bit Plane Diffusion and Chaotic Permutation for Color Image Security

Abstract

With the tremendous rise in multimedia output over the last ten years, image encryption has grown in importance as a component of information security. It is challenging to secure images using conventional encryption methods because of the intrinsic image properties that distinguish image cryptography from text cryptography. This study suggests employing binary key images for lossless encryption of color images. First, chaotic sequences from the 2D Henon map will be used to permute the locations of the pixels in the plaintext image. The key images, in this case, are bit planes created from an additional image. In order to improve the encryption image and make cracking more challenging, the bit plane will be further rotated. It concentrates on two methods for effective image encryption: bit plane slicing and bit plane spinning. In terms of a number of statistical tests, such as key experiments, information entropy experiments, and encryption quality testing, the simulation analysis also shows that the suggested technique is lossless, safe, and effective. Based on the findings, it can be shown that the new method takes less time to conceal the remaining intelligence than it does to encrypt the complete image.
