Encrypt 3D Model Using Transposition, Substitution, Folding, and Shifting (TSFS)

With the development of digital signal processing and communication networks in the past few years, using 3D object types in a wide range of applications via the internet has greatly grown. Studying 3D object protection is of high importance for the aim of maintaining confidentiality. In this paper, a new 3D objects model encryption method using Transposition Substitution Folding and Shifting (TSFS) algorithm is proposed. TSFS algorithm is utilized with 3 distinct and strong keys after 2 sub-steps for the algorithm of key generation and expansion via column shifting. With the implementation of the improved version of the algorithm, an effective and strong security system is achieved to make 3D objects more secure.
