摘要
混沌序列具有伪随机性、对初始条件强敏感性、遍历性等特点,它展现出优良的密码学性能。混沌加密是常用的数字图像加密方法之一。在此,提出一种基于Logistic的混沌加/解密模型,在图像加/解密算法中加以应用,用VB.NET实现该加/解密算法,支持多种图像格式条件下,能正确识别和显示加/解密后的图像。
Chaotic sequence has many merits such as randomicity,strong sensibility to initial condition,ergodicity etc,which presents excellent performance on cryptology.The chaos encryption is one of the common encryption algorithms.The principle of chaotic encryption algorithm based on Logistic is proposed.The encryption/decryption model is applied in image encryption/decryption.Algorithm is realized by using the development tools of Visual Basic.NET,which can recognize and display the image encryption/decryption correctly for multi - format image.
