摘　　要：针对对称加密算法和非对称加密算法,其加密效率低下、不具有在商业通信背景下的普遍适用性,文中基于矩阵易位变换原理提出了一个加密强度很高、发生碰撞概率极小、且加密效率较高的对称加密算法。本加密算法适用于对安全性要求很高、允许解密时间略长的应用场合。There are currently a symmetric encryption algorithm and the asymmetrical encryption algorithm, a considerable part of its encryption strength just passable, but like the elliptic curve encryption algorithm. Although encryption strength is extremely high, but its efficiency is very low, does not suitable for business communication under the background of general applicability. Based on the matrix translocation transform theory, this paper proposes an encryption algorithm with a high encryption intensity a small collision probability and high efficiency of the symmetrical encryption algorithm encryption. The encryption algorithm is applicable to the high security, but allows slightly longer deeryption time.
