Abstract

Information encryption is an important part of information transmission in modern society. At present, image encryption algorithms face problems such as applicability and security, which need to be solved urgently. This paper proposes an image encryption algorithm based on Arnold-Logistic sequence encryption, which uses the idea of Euler concatenation of fractions to chunk the non-equal-length images in order to perform Arnold transform. Then the random key stream is obtained for the use of Logistic sequences to perform the heteroskedastic operation on the image pixels. After experiments, the algorithm in this paper is proved to be effective in improving the cipher image security, extending the applicability of the algorithm, and also greatly reducing the computing time and space occupation.
