摘要/Abstract

摘要： 随着网络环境中图形数据的急速增长,图形数据安全处理成为了亟待解决的网络安全新挑战。对3D模型的加密也是刻不容缓。利用混沌映射提出了一种针对3D线框模型的加密方案。该方法分为两部分：混淆和扩散。利用逻辑映射生成一个随机可逆矩阵对点进行扩散,利用Arnold’s cat map对边进行置乱,加密的顶点,多边形合成在一起,形成最终的加密3D线框模型。结果表明：对每个3D线框模型都能正确的加解密。该加密方法也能很好的抵抗暴力攻击、统计攻击等。

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
