|
摘要
随着科学技术的发展,图像的应用越来越广泛,所带来的安全问题也越来越多,保护图像信息的安全是人们面临的一项严峻任务。通过对混沌系统和各种图像加密算法的学习研究,提出了一种基于优化后的Arnold置乱算法和扩散算法的图像加密算法。检测结果表明,该加密算法具有较快的加/解密速度、较高的安全性和优良的加密效果,能很好地保护图像信息安全,避免信息泄露。
With the development of science and technology, the application of images is more and more extensive, and the security problems brought by images are also increasing. It is a serious task for people to protect the security of image information. Through the study of chaotic systems and various image encryption algorithms, an image encryption algorithm based on optimized Arnold scrambling and diffusion algorithm is proposed. The detections and verifications show the encryption algorithm has a fast encryption and decryption speed, high security and good encryption effect. It can protect image information security well and avoid information leakage.
