Image encryption is one of the most common and effective methods to secure digital images. Recently, Khalid M. Hosny presented an image encryption scheme based on 6D hyper chaotic mapping and Q-Fibonacci matrix, which, despite its remarkable theoretical and practical properties, has several weaknesses, including inaccuracy of black image encryption, inappropriate white image encryption (improper entropy parameters, correlation, chi-square test, histogram, UACI, and NPCR), weak keys, inappropriate key usage. In this paper, based on Khaled Hosny's design, a new effective design is presented that has improved encryption security and efficiency. In addition, in the proposed design, a secure key and a substitution box with a high degree of transparency order, which is resistant to DPA attacks, have been added. Also, a method to improve transferring chaos parameters is also proposed. The test results show the improvement of the resistance of the proposed design against the common attacks of image encryption schemes and improvement in bandwidth consumption. Also it has been shown that the proposed scheme has produced better results in terms of both security and efficiency compared to other similar new schemes.

Hosny提出了一种基于6D超混沌映射与Q-斐波那契矩阵的图像加密方案。该方案虽然具有显著的理论与实用特性，但仍存在若干缺陷，包括黑色图像加密不精确、白色图像加密不适当（熵参数、相关性、卡方检验、直方图、UACI与NPCR指标异常）、密钥脆弱以及密钥使用不当等问题。本文在Khaled Hosny设计的基础上，提出了一种新型高效方案，有效提升了加密安全性与效率。此外，本方案增加了高透明阶安全密钥与抗DPA攻击的替换盒。同时提出了一种改进混沌参数传输的方法。测试结果表明，该方案对图像加密常见攻击的抵抗性及带宽消耗均得到改善。与其他同类新型方案相比，本方案在安全性与效率方面均取得了更优效果。
