Abstract
En 中文
In recent years, substantial work has been done for developing image encryption algorithms. Image encryption requires handling of large data, which needs computationally efficient algorithm. Chaos-based image encryption has been proposed against conventional encryption techniques. Cryptosystem using chaotic systems for image encryption has proven to be computationally effective. In this paper, a new approach to bit permutation in image encryption has been proposed using a three-dimensional puzzle along with chaos for further diffusion and confusion. The proposed encryption algorithm is tested for security and validity using various analyses. The result for tests proves that the proposed algorithm provides security against statistical and differential attacks.
