摘要

传统的加密方法通常容易受到差分、噪声和统计攻击,并且可能暴露加密图像中的模式,损害机密性并促进未经授权的访问。随着技术的快速发展和安全挑战的不可避免地增加,保护敏感图像数据免受未经授权的访问和复杂的攻击,确保高安全性应用的机密性、完整性和弹性变得非常重要。本文旨在提供一个强大、高效和安全的解决方案,以保护敏感的图像数据免受攻击。所提出的非对称图像加密技术引入了一系列创新方法的融合,包括利用Lorenz和Logistic映射的混沌行为,以及使用fisher yates洗牌算法的像素排列和洗牌。该方法不仅利用混沌系统生成鲁棒非周期加密密钥的能力,而且利用矩阵变换技术的伪随机方式来增强图像数据的机密性。该算法将图像分成16位水平比特,其中8位采用洛伦兹加密,其余8位采用逻辑加密。然后对其进行fisher-yate算法,并将图像垂直分割为16位。该算法使用4个解密密钥,否则攻击者无法恢复原始图像。通过大量的仿真实验,对所提出的加密算法的有效性进行了评价,证明了该算法在差分攻击、噪声攻击、阻塞攻击等多种攻击方面的优越性能。提出的加密技术侧重于增强安全性,不可预测的鲁棒密钥生成,先进的像素变换和多密钥保护,为保护图像数据提供可靠有效的方法,可用于军事,医疗和金融成像系统等各种应用。

Advanced image security through chaotic system-based encryption and fisher-yates matrix shuffling
Traditional encryption approaches often exhibit vulnerabilities to differential, noise, and statistical attacks, and may expose patterns in encrypted images, compromising confidentiality and promoting unauthorized access. With rapid development of technology and inevitable rise of security challenges, it becomes important to secure sensitive image data against unauthorized access and sophisticated attacks, ensuring confidentiality, integrity, and resilience in high-security applications. This paper aims to provide a robust, efficient, and secure solution for protecting sensitive image data against attacks. The proposed asymmetric image encryption technique introduces a fusion of innovative methods, including the utilization of the chaotic behavior of the Lorenz and Logistic maps, along with pixel permutation and shuffling using fisher yates shuffling algorithm. This approach not only harnesses the power of chaotic systems for generating robust non periodic encryption keys but also leverages a pseudo-random manner of matrix shuffling techniques to enhance the confidentiality of image data. The algorithm divides the image into 16 horizontal bits and applies Lorenz encryption on 8 bits and logistic encryption on the remaining 8 bits. Then fisher-yate’s algorithm is applied on them along with vertical division of image into 16 bits. The algorithm uses 4 decryption keys without which the attacker cannot recover the original image. The effectiveness of the proposed encryption algorithm is evaluated through extensive simulation experiments, which demonstrate its superior performance in terms of various attacks like differential attack, noise attack, blocking attack, etc. The proposed encryption technique focuses on enhanced security, unpredictable robust key generation, advanced pixel shuffling and multi key protection to provide a reliable and efficient approach for securing image data, which can be useful in various applications such as military, medical, and financial imaging systems and many more.
