ENCRYPTION OF IMAGE BY PLAINTEXT-RELATED SHUFFLING: A COMPREHENSIVE REVIEW

Abstract

This paper suggested a method of image encryption similar to plaintext, which used the hyper chaotic system to establish the hidden code streams used for encryption. Two plaintext-unrelated diffusion operations and one plaintext-related shuffling are involved in the encryption algorithm. The suggested encryption scheme will resist the chosen/known plaintext attacks because of the use of plaintext-related shuffling. Simulation results show that there are many good characters in the proposed method, such as fast encryption speed, wide key space, high sensitivity of the key, successful resistance to differential attack, noise-like cipher-text picture, etc., and can therefore be used in real communications. This review article provides a detailed review on the image encryption by applying the plaintext-related shuffling.
