DES_3DES
说明: DES算法是这样工作的:如Mode为加密,则用Key 去把数据Data进行加密, 生成Data的密码形式(64位)作为DES的输出结果;如Mode为解密,则用Key去把密码形式的数据Data解密,还原为Data的明码形式(64位)作为DES的输出结果。在通信网络的两端,双方约定一致的Key,在通信的源点用Key对核心数据进行DES加密,然后以密码形式在公共通信网(如电话网)中传输到通信网络的终点,数据到达目的地后,用同样的Key对密码数据进行解密,便再现了明码形式的核心数据。这样,便保证了核心数据(如PIN、MAC等)在公共通信网中传输的安全性和可靠性。 通过定期在通信网络的源端和目的端同时改用新的Key,便能更进一步提高数据的保密性,这正是现在金融交易 网络的流行做法。 下面是DES原理及实现步骤,以及VC++关于DES加密解密的详细源程序(Complete source code, calling process, detailed explanation of the principle)

SVD
% 奇异值分解 (sigular value decomposition,SVD) 是另一种正交矩阵分解法;SVD是最可靠的分解法,
% 但是它比QR 分解法要花上近十倍的计算时间。[U,S,V]=svd(A),其中U和V代表二个相互正交矩阵,
% 而S代表一对角矩阵。 和QR分解法相同者, 原矩阵A不必为正方矩阵。
% 使用SVD分解法的用途是解最小平方误差法和数据压缩。用svd分解法解线性方程组,在Quke2中就用这个来计算图形信息,性能相当的好。在计算线性方程组时,一些不能分解的矩阵或者严重病态矩阵的线性方程都能很好的得到解( Singular value decomposition (sigular value decomposition, SVD) is another orthogonal matrix decomposition method SVD decomposition is the most reliable method, but it takes more than QR decomposition near ten times the computing time. [U, S, V] = svd (A), in which U and V on behalf of two mutually orthogonal matrix, and the S on behalf of a diagonal matrix. And QR decomposition are the same, the original matrix A is no need for the square matrix. The use of SVD decomposition method are used as a solution of least squares error method and data compression. Using SVD decomposition solution of linear equations, in Quke2 on to use this information to calculate the graphics performance quite good. In the calculation of linear equations, some indecomposable matrix or serious pathological matrix of linear equations can be a very good solution)
