摘要:  

摘要: 好的图像置乱方法对提高图像置乱效果、降低密钥管理成本和提高抵抗攻击能力具有重要意义。本文提出基于骑士巡游的匀速移动算法置乱图像。首先把图像划分为区域A和区域B,然后把区域A和区域B的像素互换,使区域A的像素均匀分布到区域B中,最后使用骑士巡游算法从局部和全局2个方面进行置乱图像。实验表明本文方法能有效减少加密密钥数量,具有较好的置乱效果和较好的抗干扰性。

Abstract:  

Abstract:  Welltried scrambling method is important to improve scrambling effectiveness, reduce key management cost and improve the resistance of attacking. In this paper, an image fundamental motion scrambling method was introduced. Firstly, image was divided into part A and part B; Secondly, the swap of pixels of part A and part B was implemented in uniform velocity motion method and pixels of part A was evenly distributed in part B; Lastly, image was scrambled by knighttour transformation in global and local view. The results of experiment show this method can decrease keys with good scrambling effectiveness and antiinterference performance.
