中文摘要:为了解决加密矩阵难以构造的问题,提出一种获得整数矩阵的新算法,利用Gauss-Markov过程生成一个随机序列,将该序列转换为一系列的低阶整数矩阵,从中寻找行列式等于1的整数矩阵,并对这些矩阵进行张量积运算得到高阶加密矩阵,应用于数字图像加密。加密实例和理论分析及对比表明,该算法可自动生成安全性很高的加密矩阵,且加密结果具有良好的随机特性和自相关性,能满足密码学的要求。
外文摘要:To solve the problem of eneryption matrix is difficult to construct, a novel algorithm is proposed to get the encryption matrix: First, a stochastic sequence is generated by Gauss-Markov process. Then, it is converted into a series of low-order inte- ger matrixes and multiple the selected matrices with determinant equal to 1 each other by using tensor production method. Thus, we can construct some high order encryption matrices and use it in digital image encryption. The encryption instance and theo- retical analysis show that the proposed algorithm can produce eneryption matrices with high security, and have good random characteristics and autoeorrelation to meet the requirement of cryptography.
