摘　　要：针对移动互联网中的设备欺诈问题,提出了一种基于移动通信设备认证的动态加密方案。本方法采用分组密码体制,在分组中添加移动设备身份识别信息,然后使用动态加密方案对信息进行加密。在智能手机和个人计算机等不同平台上进行了多次实验,结果表明本方案明文和密文之间的汉明距离接近分组长度的一半256bit,密文的信息熵接近理想值8。相比于传统AES算法,本算法耗时仅需前者的1/8。Proposed a dynamic encryption algorithm based on mobile communication equipment identification,its main purpose is solves the problems of fraudulent equipment on mobile Internet.The block cipher system used to this algorithm,the equipment identification information is added in each group,and then use dynamic encryption algorithm to encrypt the information.Run the algorithm in different platforms such as smart phones and personal computer,the experimental results show that the hamming distance between plaintext and ciphertext close to half the length of a block 256bit,and information entropy of the ciphertext closer to the ideal value 8.Compared to AES algorithm,this algorithm takes only 1/8 times of the former.
