Multi-Level Chaotic Maps for 3D Textured Model Encryption

Survey on 3D Content Encryption

“…A good 3D model encryption scheme should resist all kinds of known attacks, such as various brute-force attacks and statistical attacks [4,10].…”

“…When the VFH of the encryption process different from the VFH of the decryption process. So, the statistical attack will be impossible [4]. • Distribution of occupied positions: The 3D vertices occupied positions are analyses by computing the distribution occupied position 3D vertices for normal 3D vertices and encrypted 3D vertices.…”

“…The encryption process is applied to achieve a high level of confidentiality, integrity, and security for 3D content when transmitted via unsafe channels [1][2][3]. 3D content is classified into two types: 3D surface model and 3D solid model, the 3D surface model representing the shell/boundary of the object model, and the 3D solid model representing the volume of the physical object model, the 3D surface including vertices (point cloud), polygon, and textures [4]. There are many proposed encryption schemes some of them have been adopted and standardized in the world; however, they are not suitable for 3D content, such as Advanced Encryption Standard (AES) and Data Encryption Standard (DES), because the problem of encrypting 3D content due to the application requirement and the data structure such as format compliance, content usability, complexity, real-time performance, and security level [5].…”

“…search have been proposed to develop robust 3D content encryption schemes. This survey focused on and interested in the schemes that encrypted 3D content using chaotic maps and found some papers [4,[18][19][20][21][22][23] are used chaotic maps in encrypting 3D content, and the remaining other papers [5,16,17] are used encryption schemes without chaotic maps.…”

3D Polygon Mesh Encryption Based on 3D Lorenz Chaotic Map

“…Various encryption algorithm types are proposed to convert data into unrecognized forms and prevent unauthorized user access [1][2][3][4][5]. The 3D model applications now days are developed and become more popular such as virtual reality, Computer-Aided Design (CAD), 3D printing, and digital visualization, so providing security for 3D model becomes an important matter and must provide a high level of confidentiality, integrity, and protection against unauthorized access for data, so the problem of the thread must be solved [6,7]. There are many proposed encryption schemes some of them have been adopted and standardized in the world; however, they are not suitable for a 3D model such as Advanced Encryption Standard (AES) and Data Encryption Standard (DES) because the problem of 3D model encryption due to the application requirements and the data structure such as format compliance, content usability, complexity, security level and real-time performance [8], to overcome these problems, various encryption methods based on chaotic cryptography have been implemented.…”
