摘要
基于图像加密的安全性目的,采用了基于AES算法的图像加密方法,分析了AES算法具有安全性高、图像加密效果好等优点,但鲁棒性方面有一定的局限性。为进一步提高加密效果,在此基础上提出了一种混合的加密方法,即首先进行Arnold置乱,然后再用AES算法对图像加密。通过用MATLAB仿真,分析两种加密结果,得出了改进算法鲁棒性和安全性得到改善的结论。
Based on the security of image encryption purpose, this paper using the image encryption method which is based on AES algorithm,Analyzed the AES encryption algorithms has the advantages of high safety,good effect of image encryption,but robustness aspects have certain limitations.To further improve the effect of encryption,on the basis of AESalgorithm a hybrid encryption method is proposed,namely the first Arnold scrambling,and then by AES algorithm of image encryption.Through MATLAB simulation, and analysis of two kinds of encryption as a result, it is concluded that the improved algorithm improved robustness and security.
