Multi-image Reorganization Encryption Based on S-L-F Cascade Chaos and Bit Scrambling

Abstract: Aiming at the problems of small value range of a single chaotic parameter, low sequence chaos, and transient effects, a composite chaotic system of cascaded Sine-Sine mapping, Logistic chaos and generalized third-order Fibonacci is proposed (S-L-F). The new system is highly sensitive to initial values, the maximum spectral entropy of the generated sequence can reach 0.95, and the value range of the parameter x is expanded to [0,4] compared with the traditional Logistic, indicating that the new system is suitab… Show more

“…It is clear that the PWL saturation function restricts the cosine function's input amplitude. The cosine function's input is bounded, and E determines how many periods are present in equation (2). Accordingly, the number of intersection points between the nested COS-PWL function and the x-axis will increase with E.…”

“…More elegant than conventional chaotic systems, multi-scroll and multi-wing chaotic systems are crucial for chaotic image encryption [1][2][3], chaotic cryptanalysis [4,5], and communication security [6]. Therefore, many people are committed to designing and implementing complex multi-scroll (or multi-wing) chaotic attractors [7,8].…”

“…The treated samples were sectioned using an EMUC ultramicrotome with a thickness of 400 nm, observed with an optical microscope (BX53M, Olympus, Japan), taken fiber crosssectional images using an Oplenic digital camera, and used the grayscale calibration function in the Oplenic software to fix the background grayscale value of the image to 140. The center of the fiber cross-section is the 0 point, and the points are taken at 1 μm intervals along the diameter direction on both sides (Figure 2), the fiber cross-section photos are used for the optical density (OD) selection calculation using ImageJ software, Equation ( 4) is the OD calculation formula, 21 and the average OD of the circular area with 1um diameter is taken as the OD value at each point, OD ±4 represents the fiber skin OD, OD 0 represents the fiber core OD, and Equation ( 5) is the calculation formula for the degree of difference of the fiber's skin core OD.…”

“…While, in fact, not only are there changes in the proportion of the region, but also the structure changes in each region. [44,58] It is a better method to characterize the fiber structure by its properties such as chemical functional groups, molecular structure, physical properties, and so on. [59][60][61]…”
