针对超混沌系统图像加密算法的选择明文攻击
Chosen Plaintext Attack for Hyper-chaotic System Image Encryption Algorithm
摘要
Abstract
Hyper-chaotic system image encryption algorithm HYPERHIE uses elementary transformation and exjunction to encrypt, so it is difficult to resist various attacks. Aiming at three steps of HYPERHIE including key generation, pixel scrambling, image diffusion and confusion, this paper chooses three kinds of plaintext matrixes to do chosen plaintext attack without knowing encryption key. An instance shows that the attack method can decode ciphertext with low computing costs.关键词
