Summary: This paper proposes a low complexity and low operation color image encryption algorithm based on a combination of bit-plane and chaotic systems. The algorithm exchanges the higher and lower bits of binary gray values, scrambles the position of each four-bit binary number with a logistic chaotic sequence, and converts the binary numbers into hexadecimal numbers to reduce computational complexity. The algorithm also uses chaos sequences to permute the position and gray pixel values of the transformed image, achieving a better encryption effect and resistance to differential attacks.

Summary: This article proposes a new spatiotemporal chaotic system named improved sinusoidal dynamic non-adjacent coupled mapping lattice (ISDNCML) with an infinite parameter range. The performance test shows that ISDNCML has more random lattice interaction, better chaos, and excellent cryptography. Based on the characteristics of ISDNCML, a globally coupled private image encryption algorithm is proposed, which ensures the security of private information by introducing ill-conditioned dynamic diffusion into the private area during encryption. The security and practicability of this cryptographic system are verified through analysis and various tests.

Summary: This paper investigates the correlation between the Lyapunov exponent (LE) and the randomness in chaotic maps. By constructing a generic n-dimensional non-degenerate hyper chaotic map (nD-NDCM) model with adjustable LE, the limitations of existing chaotic maps in cryptography, such as lack of ergodicity, weak positive LE, and poor randomness, can be overcome. The dynamic performance of 2D-NDCM and 3D-NDCM based on this model is analyzed using bifurcation diagrams, phase diagrams, and LE. Through analyzing the iterative sequence using NIST SP800-22 and TestU01, the corresponding LE interval with good randomness can be determined. The established correlation allows for the direct and feasible construction of multi-dimensional chaotic maps with good randomness.

Summary: The cryptanalysis of the S-Box construction in AES revealed that the number of irreducible polynomials can be extended to 30, and by ignoring the existence of fixed points and reverse fixed points, the affine transformation constant c can be selected from [01, FF]. It was also found that the fixed nature of the S-Box in AES poses potential security risks to the algorithm. Based on this analysis, a non-degenerate 2D enhanced quadratic map (2D-EQM) was constructed for generating affine transformation matrices and constants, resulting in a batch of strong S-Boxes with high nonlinearity. Statistical analysis showed that a significant number of these generated S-Boxes maintained a nonlinearity of 112.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

Summary: Due to the complexity of resolving object form and pose in images, new vision algorithms prioritize identification and perception over accurate coordinate measurement. However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
