This paper introduces chaotic image encryption to realize the secure transmission of digital images, and combines 1D and 3D chaotic systems into an image encryption algorithm. Firstly, two sets of logistic chaotic sequences were generated iteratively for pixel permutation, so were the initial values of the Bao system. Then, the chaotic sequence for pixel permutation and diffusion was generated based on the plaintext pixel value and Bao system. After that, the plaintext image was encrypted and decrypted by encryption and decryption formulas. Finally, the encryption process was simulated, and the algorithm performance was analyzed in terms of key space and correlation of adjacent pixels. The results show that our algorithm achieved better security than the traditional methods.

“…In [20], a color image encryption algorithm proposed by using coupledmap lattices (CML) and a fractional-order chaotic system to increase the robustness and security of the system. A combination of two or more chaotic maps were also analyzed to enhance the complexity of the cryptosystem [21]. The two Logistic sequences were used to label the row coordinates and column coordinates of scrambled image and then MOD and XOR operations were applied to diffuse the plain image [22].…”

A cryptosystem designed by using the combined features of fractal function and chaotic map, provides a secure and real time encryption environment. In this paper, a 2D-chaotic map is employed to create a chaotic key sequence to comply with the requirement of the key sensitivity. The set of initial values of the chaotic map has derived by iterating a conjugate transcendental fractal function (CTFF) i.e. +1 = (sin(2)) +. The fractal function produced three sets of initial values after iterating it using Picard, Mann, and Ishikawa iteration methods. Resultantly, three chaotic key sequences will be generated by executing 2D Sine Tent composite map (2D-STCM) for each set of initial values. Afterwards, perform zigzag scanning to each key stream to decorrelate the adjacent image pixels and combined them using XOR operation. By using a different summation of plain image pixels for each pixel encryption, improves the cryptosystem resistant against known/chosen-plaintext attack. Moreover, an encryption of a plain image pixel achieved using corresponding key sequence pixel and a previously ciphered pixel value. The proposed encryption/decryption scheme is evaluated using key space analysis, key sensitivity analysis, differential analysis and other statistical analyses. The performance result indicates the given scheme is efficient and reliable to be used with great potential for a secure image transmission application.

In this paper, an effective framework for chaotic encryption based on a three-dimensional logistic map is presented together with secure hash algorithm-3 (SHA-3) and electrocardiograph (ECG) signal. Following the analysis of the drawbacks, namely, fixed key and low sensitivity, of some current algorithms, this work tries to solve these two problems and includes two contributions: (1) removal of the phenomenon of summation invariance in a plain-image, for which SHA-3 is proposed to calculate the hash value for the plain-image, with the results being employed to influence the initial keys for chaotic map; (2) resolution of the problem of fixed key by using an ECG signal, that can be different for different subjects or different for same subject at different times. The Wolf algorithm is employed to produce all the control parameters and initial keys in the proposed encryption method. It is believed that combining with the classical architecture of permutation-diffusion, the summation invariance in the plain-image and shortcoming of a fixed key will be avoided in our algorithm. Furthermore, the experimental results and security analysis show that the proposed encryption algorithm can achieve confidentiality.
