“…2020, 10, x 2 of 11 diffusion was proposed, which has weak security defects. However, Ming Li et al find out the equivalent key streams and attacked the scheme in [33] and attacked the scheme. However, most chaotic maps, used in generating the security key in encryption process, are multi-dimensional, which cause high level computation complexity.…”

Security of image communication is more and more important in many applications such as the transmission of military and medical images. To meet the requirement, a new color image encryption algorithm using a new one-dimension (1D) chaotic map was proposed recently, which can resist various attacks because the range of the new chaotic map is larger than that of the previous ones. In our study, the security of the new original method is analyzed and a novel attack method is proposed. It is demonstrated that the scheme is not secure under chosen-plaintext attack, by which the encrypted image can be successfully converted into the corresponding plaintext image without any error.

“…The two commonly used confusion algorithms are: performing row and column confusion on a image, and reshaping a two-dimensional image into a vector, and then performing position confusion on it [17][18][19]. The basic diffusion methods are based on an XOR operation or mod operation after addition [20,21].…”

We propose a new chaotic map combined with delay and cascade, called tent delay-sine cascade with logistic map (TDSCL). Compared with the original one-dimensional simple map, the proposed map has increased initial value sensitivity and internal randomness and a larger chaotic parameter interval. The chaotic sequence generated by TDSCL has pseudo-randomness and is suitable for image encryption. Based on this chaotic map, we propose an image encryption algorithm with a symmetric structure, which can achieve confusion and diffusion at the same time. Simulation results show that after encryption using the proposed algorithm, the entropy of the cipher is extremely close to the ideal value of eight, and the correlation coefficients between the pixels are lower than 0.01, thus the algorithm can resist statistical attacks. Moreover, the number of pixel change rate (NPCR) and the unified average changing intensity (UACI) of the proposed algorithm are very close to the ideal value, which indicates that it can efficiently resist chosen-plain text attack.

“…Up to now, a large number of image cryptosystems based on chaotic systems have been found to be unsafe [24,25,26,27,28,29,30,31]. These cryptosystems cannot resist chosen/known plaintext attacks [32,33,34,35,36,37,38,39,40,41] because they possess plaintext-unrelated equivalent keys. A chosen plaintext attack method in [32] cracked the scheme in [24] with only 18 attacks for 256×256-sized images.…”

“…Then they suggested an improved scheme based on [28]. However, this improved scheme [35] is still unable to resist the chosen plaintext attack method described in [37]. In [38], Ma et al cracked the image cryptosystem in [29] using the chosen plaintext attack method with only 14 pairs of plaintext and cipher-text images for the 256×256-sized images.…”

A new image cryptosystem based on neuron-like scheme is proposed in this paper. As a nonlinear component of image cryptosystem, neuron-like learning algorithm can realize a kind of memorable diffusion algorithm, thus realizing the plaintext-related image encryption algorithm. Through the feedback operation, the inputs and weights of the neuron are regulated by the information of the image, and then they are used to diffuse the image information. According to the needs of application scenarios, the number of inputs of the neuron can be adjusted so that the image cryptosystem can be applied to different security requirements. The simulation results show that the proposed image encryption system is extremely sensitive to the secret keys, the equivalent keys and the plain images, and also possesses the high security and adaptive characteristics. The image cryptosystem can be applied to the actual applications of image information security.
