【摘要】 设计了一种新的分组密码算法,该算法利用矩阵乘法的扩散作用与专门设计的一种矩阵运算的混乱作用实现对信息的加密.算法有较高的安全性,能够抵抗现有的密码分析方法,它既适合字母文字信息的加密,也适合非字母的中文信息对称加密.算法所需代码少、计算量小,能够嵌入到移动电话等移动数字设备中,对移动电子商务信息安全具有一定的实际意义.更多还原

【Abstract】 A new block cipher is designed where the diffusion of matrix multiplication is combined with the confusion of specially designed matrix operation to encrypt information. The strong security to all known cryptanalysis ensures the encryption of both letter information and nonletter chinese character information. Less code and computation needed facilitate its embedment into digital equipment to implement encryption, such as mobile phone. Thus the newly proposed cipher is of interest to mobilecommerce information security.更多还原
