Abstract

Abstract: With the rapid growth of graphics data in the network environment, the security of graphics data has become a new challenge of network security that needs to be solved urgently. Encryption of 3D models is also urgent. In this paper, an encryption scheme for 3D wireframe model is proposed by using chaos mapping. The method is divided into two parts: confusion and diffuse. A random invertible matrix is generated by using logical mapping to spread the points. The side is scrambled by Arnold's cat map, then the encrypted vertices and polygons are combined to form the final encrypted 3D wireframe model. The extensive tests results show that each 3D wireframe model can be properly both encrypted and decrypted. The encryption method can also well resist violent attacks, statistical attacks and so on.

Key words: 3D wireframe, chaotic logistic map, Arnold's cat map, encryption, VFH
