Propomos a criptografia perceptual baseada em cubo (C-PE), que consiste em embaralhamento de cubo, rotação de cubo, transformação negativa/positiva de cubo e embaralhamento de componente de cor de cubo, e descrevemos sua aplicação ao sistema de criptografia e compressão (ETC). de Motion JPEG (MJPEG). Especialmente, a rotação do cubo substitui os blocos nos quadros originais por aqueles não apenas nos outros quadros, mas também nos lados do cubo em profundidade (lados espaço-temporais), ao contrário da criptografia perceptual baseada em blocos convencional (B-PE). Como dificulta a observação intra-bloco e evita a descriptografia não autorizada de apenas um único quadro, é mais robusto que o B-PE contra métodos de ataque sem qualquer chave de descriptografia. No entanto, como os quadros criptografados incluindo os blocos dos lados espaço-temporais afetam ligeiramente o desempenho da compressão MJPEG, também desenvolvemos uma versão do C-PE sem lados espaço-temporais (NSS-C-PE) que dificilmente afeta o desempenho da compressão. O C-PE torna a sequência de vídeo criptografada robusta contra o único ataque de força bruta algorítmica (ABF) baseado em quadro único com apenas 21 cubos. Os resultados experimentais mostram a eficiência de compressão e a robustez da criptografia do sistema ETC baseado em C-PE/NSS-C-PE. O sistema ETC baseado em C-PE mostra resultados mistos dependendo dos vídeos, enquanto o sistema ETC baseado em NSS-C-PE mostra que o BD-PSNR pode ser suprimido para cerca de -0.03dB, não dependendo dos vídeos.

Abstract: We propose the cube-based perceptual encryption (C-PE), which consists of cube scrambling, cube rotation, cube negative/positive transformation, and cube color component shuffling, and describe its application to the encryption-then-compression (ETC) system of Motion JPEG (MJPEG). Especially, cube rotation replaces the blocks in the original frames with ones in not only the other frames but also the depth-wise cube sides (spatiotemporal sides) unlike conventional block-based perceptual encryption (B-PE). Since it makes intra-block observation more difficult and prevents unauthorized decryption from only a single frame, it is more robust than B-PE against attack methods without any decryption key. However, because the encrypted frames including the blocks from the spatiotemporal sides affect the MJPEG compression performance slightly, we also devise a version of C-PE with no spatiotemporal sides (NSS-C-PE) that hardly affects compression performance. C-PE makes the encrypted video sequence robust against the only single frame-based algorithmic brute force (ABF) attack with only 21 cubes. The experimental results show the compression efficiency and encryption robustness of the C-PE/NSS-C-PE-based ETC system. C-PE-based ETC system shows mixed results depending on videos, whereas NSS-C-PE-based ETC system shows that the BD-PSNR can be suppressed to about -0.03dB not depending on videos.
