1D Sine-Map-Coupling-Logistic-Map for 3D model encryption

Abstract

With the rise of technologies of VR technology, AR technology, and 3D printing, the application of 3D models has become more and more extensive. The data of the 3D model is the floating point and has a unique storage format, and the traditional 2D image encryption algorithms are unsuitable for 3D models. Therefore, based on 1D Sine-Map-Coupling-Logistic-Map (1D-SMCLM), a 3D model encryption algorithm is designed in this paper. The 1D-SMCLM is a new chaotic system with large parameter space and good chaotic characteristics. The keystream generated by the 1D-SMCLM has good randomness and is very suitable for cryptographic systems. In the new encryption algorithm (SMCLM-3ME), the vertices of the 3D models are divided into integer and decimal vertices. The integer part is encrypted by the strategy of simultaneous scrambling and diffusion. The 3D ciphertext model is obtained by combining the integer and fractional parts. Experimental results show that the SMCLM-IE exhibits excellent performance.

“…Combining the Sine chaotic mapping with the trigonometric function Cosine and then applying the binary segmentation concept for encryption enhances the complexity and nonlinear features of the algorithm. This approach also boosts the algorithm's fault tolerance and resistance to attacks [18][19][20]. ISCM can exhibit diverse behaviors across a wider range of inputs, offering flexibility and applicability for practical applications [21].…”
