摘要
作为一种重要的图像加密技术,数字图像置乱近年来已成为信息安全领域的研究热点。对基于Arnold变换在数字图像置乱中的应用进行了研究,实现了Arnold置乱算法和置乱度,利用其周期性对数字图像进行了置乱和恢复,并且对该算法进行了攻击实验,最后实验验证。结果表明,应用Arnold置乱方法对图像加密,可以有效地提高图像的安全性,具有工程实用性。
As an important image encryption technology, digital image scrambling has been an hot research field in information security. This paper studies the application based on Arnold transformation in digital image scrambling, realizes Arnold scrambling algorithm and scrambling degree, uses its cyclical to scramble and recover the digital image, finally implements the algorithm. The experimental results show that this algorithm can improve the security of image effetely, and has high practicability.
