Abstract

Image encryption is essential for safeguarding unauthorized access to visual content. However, with the emergence of numerous image encryption algorithms, it has become apparent that these algorithms often lack mechanisms to safeguard encrypted images from tampering, making it difficult to detect any changes that may occur during transmission or storage. Additionally, the limitations of permutation-diffusion model encryption algorithms have become increasingly apparent. While many existing algorithms attempt to resist differential attacks through the use of “one-time keys” or “multi-round diffusion” techniques, these approaches often result in increased complexity and reduced time efficiency. In this paper, we present an improved chaotic system and leverage it to develop a novel image encryption algorithm with inherent anti-tampering capabilities. This algorithm replaces the traditional one-time key with a fixed key, thereby enhancing security while also improving encryption efficiency. Furthermore, we integrate watermarking technology to address the challenges of detecting image tampering during storage and transmission. Experimental results demonstrate that the proposed algorithm exhibits robust performance, effectively resisting various forms of attacks while maintaining strong anti-tampering capabilities.
具有防篡改攻击能力的新型图像加密算法
图像加密对于防止未经授权访问图像内容至关重要。然而,随着众多图像加密算法的出现,人们发现这些算法往往缺乏防止加密图像被篡改的机制,因此很难检测到传输或存储过程中可能发生的任何变化。此外,置换扩散模型加密算法的局限性也日益明显。虽然许多现有算法试图通过使用 "一次性密钥 "或 "多轮扩散 "技术来抵御差分攻击,但这些方法往往会导致复杂性增加和时间效率降低。在本文中,我们提出了一种改进的混沌系统,并利用它开发了一种具有内在防篡改能力的新型图像加密算法。该算法用固定密钥取代了传统的一次性密钥,从而在提高加密效率的同时增强了安全性。此外,我们还集成了水印技术,以应对在存储和传输过程中检测图像篡改的挑战。实验结果表明,所提出的算法性能稳健,能有效抵御各种形式的攻击,同时保持强大的防篡改能力。
