摘要
数字图像在远距离传输时必须保证其完整性和安全性。采用数字图像本身的MD5值作为位加密周期序列,设计了一种简单、高效而且实用的图像加密算法。该算法针对数字图像的应用特点,既实现了图像完整性的验证功能又解决了图像安全性的问题。
In long-distance transmission,digital images have to be ensured their integrity and security.In this paper we designed a simple,efficient and practical image encryption algorithm using MD5 value of the digital images themselves as the cycle bit encryption sequence.The algorithm is designed for the application features of the digital images,it achieves the integrity verification of the images and resolves the security problem of the images too.
