“…Generally, by following References, statistical analysis (with respect to the security of an image encryption technique) of the proposed scheme has been evaluated here. A good cryptography algorithm is supposed to create the cipher image confusing enough so that it is hard to an attacker to revel useful information from a statistical viewpoint.…”

This paper presents an image encryption technique using the LFSR (Linear‐Feedback Shift Register)‐based multiple ants cellular automation with Chaotic map, where LFSR is used to produce pseudo random series that shuffle the pixel positions of an image. We then are using a shared secret key and chaotic map, the each pixel's intensity value of an image is altered and finally gets a ciphered image. Analysis of our proposed method shows a major protection for different statistical attacks. Moreover, our method provides better tradeoff between the entropy and correlation coefficients among the existing methods. The results of investigation and mathematical analysis confirm the protection, flexibility, correctness, reliability, and the robustness of the proposed scheme. The different security analysis confirms that the new encryption algorithm has higher security.

“…Hash function based on continuous chaotic system is rarely discussed yet, Ahmad et al [16] designed a cryptographic one-way hash function by exploring the complex dynamics of twelve-terms 4D nonlinear system. Discrete classical chaotic systems and their deformations, such as hyper chaotic system [17], hyper chaotic complex system [18], and fractional chaotic system [19], can be served as sponge function to absorb message via injecting impulse [20] or parameter perturbation [21], [22].…”

Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First, the input message is divided into four 1D arrays, to generate four perturbation sequences via parameter updating rule, the perturbed parameters are still within their significant intervals, to make the system remain a hyperchaotic state. Each iteration of the discrete hyperchaotic system uses updated parameters, and the last state variable values are extracted to generate a len-bit hash value by transformation algorithm. The algorithm is so flexible that it can generate 256, 512, 1024 or longer hash value through parameter switcher. The experimental evaluation and comparison demonstrated the hash function's resistance to differential attack and second pre-image attack. The proposed hash function can be applied in the identification, information integrity, and figure signature.

“…The hyperchaotic map has at least two positive Lyapunov exponents. The hyperchaotic systems have more variables and parameters, a more complex structure, better ergodicity, wider chaotic intervals and better dynamic performance [23], [27], [45]. Yuan et al [23] proposed a parallel image cryptosystem using a 5D hyperchaotic system.…”

Image encryption is an important method for protecting private data during communication. This paper proposes a novel hyperchaotic image encryption algorithm based on stochastic signal insertion and block permutation. First, the 5D hyperchaotic system is applied to generate pseudorandom number sequences. The SHA-256 hash function and secret keys are used to produce the initial values of the cryptosystem. The hash values can effectively enhance the sensitivity to plain image. To enlarge the key space and change orbit of cryptosystem, some stochastic signals are inserted during iteration. The plain image is equally divided into two parts. An X-coordinate, a Y-coordinate and a control table are established with produced pseudonumber sequences. The pixel is swapped with another pixel in the current block or another block depending on the control table. Cyclic shift is performed during the diffusion process. Performance and security analyses are executed to verify the effect of the proposed scheme. It is clear that the proposed scheme has a large key space and is highly sensitive to plain image and secret keys. Moreover, the cryptosystem has low computation complexity and can resist correlation analysis, entropy analysis, statistical attack, differential attack, noise and data loss attacks.
