“…To improve the security and complexity of picture encryption, the usage of 4D chaotic maps has been proposed. The 4D chaotic map generates more complex and unpredictable sequences than typical 2D or 3D maps [6][7][8]. Some previous works have utilized 4D chaotic maps for image encryption, including Chen's system [9], Lorenz's system [10], and the hyperchaotic Chen system [11].…”

With technological advances, sharing sensitive information, such as multimedia data, especially images, is common. To protect the integrity of such data, advanced encryption algorithms are utmost necessary. The proposed encryption scheme introduces a novel approach that capitalizes on the distinct characteristics of users' authenticated usernames to dictate the sequence in which image blocks are encrypted. The methodology encompasses two key strategies. Initially, a set of four individual chaotic maps - Sin, Chebyshev, Logistic, and Gaussian - are employed for encryption. Also, the image blocks are encrypted with a novel 4D chaotic map. The process begins with segmenting an N×N×3 color image into its red, blue, and green constituents, each of size N×N. These constituents are further subdivided into four arrays, each sized (4×4) × (N/4) × (N/4). The encryption process for various image bands is based on the use of chaotic sequences generated by schemes 1 and 2. These resulting sequences serve as the fundamental encryption keys, guiding a variety of processes including both confusion and diffusion. The proposed encryption schemes, Scheme 1 and Scheme 2 were rigorously evaluated through extensive simulations, comparing their performance with a traditional algorithm. Both procedures demonstrated robustness against statistical analysis differential attacks and showcased NPCR and UACI values closely approximating ideal standards of 99.6 and 33.4, respectively. Notably, Scheme 2, employing the proposed 4D map, outperformed Scheme 1, which used four different chaotic maps, particularly in terms of NPCR and UACI. The schemes exhibited a significant key space of 2540, rendering decryption infeasible within an astronomical time frame of 9.449 × 10130 years. Further, entropy and correlation analysis validation revealed values close to 7.99 and 0, aligning with traditional algorithms' values. Additionally, pixel distribution analyses indicated uniformity along horizontal, vertical, and diagonal directions. The paper introduces an innovative encryption approach that capitalizes on user-specific characteristics and demonstrates superior security and performance compared to conventional methods.

This paper proposes a new 4D hyperchaotic system based on a modified 3D Lorenz chaotic system. The stability of equilibrium points in this hyperchaotic system is analyzed, with a notable feature being the presence of only one equilibrium point. Subsequently, dynamic characteristics of the new system, such as Lyapunov exponents' spectrum, bifurcation diagram, and chaotic attractors, are analyzed using MATLAB numerical simulation software. The numerical analysis indicates that the hyperchaotic system exhibits hyperchaotic characteristics over a wide range of parameterdvalues, and its chaotic attractor manifests four states: hyperchaotic, chaotic, periodic, and quasi-periodic. This illustrates the complex dynamic behavior of the hyperchaotic system. Experimental validation is then conducted using embedded hardware STM32, reproducing the four types of chaotic attractors observed in numerical analysis and confirming the accuracy of theoretical analysis. The proposed new hyperchaotic system is deemed effective and reliable. Finally, the system is applied to image encryption, presenting a novel encryption method based on the hyperchaotic system. The designed hyperchaotic encryption sequence satisfies 15 tests of the NIST SP800-22 standard, and experimental verification using STM32 demonstrates the effectiveness, simplicity, non-linearity, and high security of the proposed image encryption algorithm. This method can be extended to applications such as audio encryption, image encryption, video encryption, and other fields.
