摘要
介绍一种全新的基于置换密钥矩阵(RKM)的非线性多米诺查表加密算法。RKM算法以一个16×16阶置换矩阵为密钥,将分组明文以字节的方式通过置换矩阵查表得到密文;同时RKM加密算法还引入置换密钥矩阵横向和纵向特征因子以及多米诺查表,使其安全性得到进一步提高。
A novel encryption algorithm based on the replace key matrix （RKM） is presented. RKM cryptosystem is a block cipher operated on a 128 bits or a 256 bits block of the plaintext. The eneryption algorithm for RKM is based on a 16×16 key matrix, and the ciphertext is deduced by the byte of RKM converted from the plaintext. The horizontal and vertical eigenvectors, the domino affect are introduced in RKM. The algorithm design and the security analysis are presented and the security of RKM is improved.
