Cet article propose un schéma de chiffrement basé sur la permutation de blocs (BPBE) pour le système de chiffrement puis compression (ETC) qui améliore le brouillage des couleurs. Une image BPBE peut être obtenue par quatre processus : brouillage de position, rotation/retournement de bloc, transformation négatif-positif et mélange des composants de couleur, après avoir divisé l'image originale en plusieurs blocs. Le schéma proposé brouille les composants R, V et B indépendamment dans le brouillage de position, la rotation/retournement de bloc et la transformation négative-positive, en attribuant des clés différentes à chaque composant de couleur. Le schéma conventionnel prend en compte l'efficacité de la compression en utilisant JPEG et JPEG 2000, qui nécessitent par défaut une conversion des couleurs avant le processus de compression. Par conséquent, le schéma conventionnel brouille les composantes de couleur de manière identique dans chaque processus. En revanche, le schéma proposé prend en compte la compression basée sur RVB, telle que JPEG-LS, et peut ainsi augmenter l'étendue du brouillage. La résilience face au solveur de puzzle (JPS) peut par conséquent être augmentée grâce à la distribution de couleurs plus large de l’image BPBE. De plus, l’espace clé de résilience contre les attaques par force brute a également été élargi de façon exponentielle. De plus, le schéma proposé peut maintenir l’efficacité de la compression JPEG-LS par rapport au schéma conventionnel. Nous confirmons l'efficacité du schéma proposé par des expériences et des analyses.

Abstract: This paper proposes a block-permutation-based encryption (BPBE) scheme for the encryption-then-compression (ETC) system that enhances the color scrambling. A BPBE image can be obtained through four processes, positional scrambling, block rotation/flip, negative-positive transformation, and color component shuffling, after dividing the original image into multiple blocks. The proposed scheme scrambles the R, G, and B components independently in positional scrambling, block rotation/flip, and negative-positive transformation, by assigning different keys to each color component. The conventional scheme considers the compression efficiency using JPEG and JPEG 2000, which need a color conversion before the compression process by default. Therefore, the conventional scheme scrambles the color components identically in each process. In contrast, the proposed scheme takes into account the RGB-based compression, such as JPEG-LS, and thus can increase the extent of the scrambling. The resilience against jigsaw puzzle solver (JPS) can consequently be increased owing to the wider color distribution of the BPBE image. Additionally, the key space for resilience against brute-force attacks has also been expanded exponentially. Furthermore, the proposed scheme can maintain the JPEG-LS compression efficiency compared to the conventional scheme. We confirm the effectiveness of the proposed scheme by experiments and analyses.
