“…The technique presented in this paper utilizes plain image pixel intensities for the modification of a parameter used by LM during the generation of one of the pseudorandom sequences. While similar techniques have been already investigated [17] and also experimentally tested [18,19], our proposal should be more effective-it should achieve comparable results with these, but with higher encryption speeds of older and simpler algorithms that utilize plaintext-related steps in the confusion or diffusion stage. The values of the commonly used numerical parameters of our proposal should be comparable with more complex approaches that use hash functions [32][33][34][35][36][37].…”

“…While the previous techniques focused on introducing plaintext-related steps mainly in the confusion and diffusion stages, the presented algorithm uses plain image pixel intensities to affect parameter values during the generation of a pseudo-random sequence. While some theoretical foundations were already laid out by Liu and Miao in 2016 [17] and some algorithms were even proposed, e.g., those by Chai et al in 2020 [18] or Zheng and Hu in 2021 [19], all of these have significantly higher computational complexity than other plaintext-related techniques. The algorithm presented in this paper should provide a solution that has the benefits of a plaintext-related pseudo-random sequence combined with the favorable computational complexity of approaches that use a plaintext-related step during the confusion or diffusion stage.…”

This paper deals with a plaintext-related image encryption algorithm that modifies the parameter values used by the logistic map according to plain image pixel intensities. The parameter values are altered in a row-wise manner, which enables the usage of the same procedure also during the decryption. Furthermore, the parameter modification technique takes into account knowledge about the logistic map, its fixed points and possible periodic cycles. Since the resulting interval of parameter values achieves high positive values of Lyapunov exponents, the chaotic behavior of the logistic map should be most pronounced. These assumptions are verified by a set of experiments and the obtained numerical values are compared with those reported in relevant papers. It is found that the proposed design that uses a simpler, but well-studied, chaotic map with mitigated issues obtains results comparable with algorithms that use more complex chaotic systems. Moreover, the proposed solution is much faster than other approaches with a similar purpose.

A new chaotic system is obtained by changing the number of unknown parameters. The dynamical behavior of the chaotic system is investigated by the exponential change of the single unknown parameter and the state variable in the nonlinear term of the system. The structure of the newly constructed chaotic system is explored. When the number of the same state variables in the nonlinear term of the chaotic system varies, the system’s dynamic behavior undergoes complex changes. Moreover, with the exponential change of a single-state variable in a three-dimensional system, the system maintains the chaotic attractor while the state of the attractor changes. On this basis, the Lyapunov exponent, bifurcation diagram, complexity, and 0–1 test are used to compare and analyze this phenomenon. Through circuit simulations, the chaotic characteristics of the system under different conditions are further verified; this provides a theoretical basis for the hardware implementation of the new system. Finally, the new chaotic system is applied to an image encryption system with the same encryption and decryption processes. The comparison shows improved encryption and decryption characteristics of image encryption systems.
