The research and design of encryption of electric infrared image based on a mixture of AES and chaotic encryption theory

在泛在电力物联网的迅速发展的时代,如何让物联网变得更安全可靠成为了当代信息安全领域的研究热门。本研究以网络信息安全问题为切入点,利用了AES(Advanced Encryption Standard)算法混淆密码的功能,以及混沌加密算法在生成序列时的伪随机性,提出了一种将AES加密与混沌加密混合的新型加密算法。以电气红外图像为示例,通过Matlab完成了对示例图像的混合加密。为了验证混合加密算法的安全性,实验以相邻像素相关性和直方图为评估标准,数据表明混合加密算法比单方面的AES加密算法的安全性更高,其应用前景更加广阔。

With the rapid development of ubiquitous power Internet of Things,it has become much more important to improve its reliability and security.Taking the network information security problem as the breakthrough point,based on the feature of the AES(Advanced Encryption Standard)algorithm and the pseudo-randomness of the chaotic encryption algorithm when generating sequences,a hybrid of AES encryption and chaotic encryption algorithm is proposed.Taking electrical infrared image as an example,the hybrid encryption of the sample image is completed through Matlab.In order to verify the security of the hybrid encryption algorithm,the experiment uses adjacent pixel correlation and histogram as evaluation criteria.The result shows that the hybrid encryption algorithm is more secure than the unilateral AES encryption algorithm,and its application prospects are broader.
