希尔密码(Hill Cipher)是运用基本矩阵论原理的替换密码,由Lester S. Hill在1929年发明。 每个字母当作 $ 26 $ 进制数字:$ A=0, B=1, C=2,\cdots $ 一串字母当成 $ n $ 维向量,跟一个 $ n \times n $ 的矩阵相乘,再将得出的结果模 $ 26 $ 。 注意用作加密的矩阵(即密匙)在 必须是可逆的,...

Hill Cipher EncryptionWe have to do encryption on the message 'ACT' (n=3). The key is 'GYBNQKURP' which can be written as the n x n matrix that is 3 x 3 matrix,The message for encryption 'ACT' is written as a vector,The enciphered vector is given as,...

3) Hill Cipher The Hill cipher is based on polygraphic substitution that is it works on multiple letters at the same time, introduced by Lester Hill in 1929. This method related to the matrix theory of mathematics, specifically how to compute the inverse of a matrix. ...
