数字签名是一个数学计划演示数字消息或文档的真实性。有效的数字签名给的收件人的理由相信该消息由已知发件人，这样发件人不能否认曾经发送过 （认证和不可否认性） 的消息，该消息过境 （完整性） 中没被更改。软件分发、 金融交易和其他重要探测伪造或篡改的情况，通常使用数字签名。

平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).
