Three-dimensional point-cloud data has been enormously abundant with the emergence of numerous technologies for 3D data acquisition, processing, and visualization. Encryption algorithms have been recently introduced to ensure secure storage and communication for this type of data. However, maintaining the correctness and the geometric stability of such algorithms are still key challenges towards the construction of reliable, trustful, and practical ciphers of 3D point clouds. Few attempts have been made to establish geometrically stable algorithms for 3D point cloud encryption, without compromising the cipher robustness. In particular, Jolfaei et al. [IEEE Transactions on Information Forensics and Security , vol. 10, no. 2, pp. 409-422, 2015] proposed a 3D object encryption algorithm along with geometric notions of dimensional and spatial stability. However, these notions are not consistent and the geometric stability and correctness of that cipher are not guaranteed as we show through counterexamples. In this paper, we introduce an enhanced cipher with correctness, reversibility, and geometric stability guarantees. The soundness and significance of the proposed scheme are demonstrated by rigorous mathematical proofs, extensive experimentation, and comparisons against state-of-the-art methods.

“…These algorithms have led to the development of the Data Encryption Standard (DES) [7], the Advanced Encryption Standard (AES) [35], and the RSA encryption algorithm [34]. While several 1D and 2D ciphers have been designed particularly for digital images, the 3D object encryption algorithms are still quite limited [4,9,32].…”
