一种基于DCT和混沌序列的图像加密算法
An Encryption Algorithm of Image Based on Chaotic Sequences and DCT
摘要
Abstract
This paper puts forward a kind of image encryption algorithm based on the discrete cosine transform(DCT )and chaotic system .firstly ,the DCT is used to compress image in frequency domain ,then replacement rule and chaotic sequence of symbols was generated respectively by using chaotic system to en‐crypt the compressed data in the frequency domain ,Simulation results show that the proposed algorithm can not only make good encryption effects ,but has the certain compression performance .At the same time , the algorithm can make the appropriate adjustments to the compression and encryption effect according to the need .关键词
