In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.

Bill Cipher is a two-dimensional interdimensional dream demon from the now destroyed dimension, Euclydia. Formerly existent only in the Mindscape, Bill briefly succeeded in gaining access to the real world and a physical form. He had been running amok in …

Hill Cipher is a polyalphabetic cipher created by extending the Affine cipher, using linear algebra and modular arithmetic via a numeric matrix that serves as an encryption and decryption key. How to encrypt using Hill cipher?

2020年8月8日 · 希尔密码属于古典密码，是运用矩阵原理的替换密码，发明者为 Lester S. Hill，发明时间是 1929 年。 希尔密码在加解密过程中会大量使用到线性代数中的矩阵知识，所以对数学能力要求会高一点。 下面是学习希尔密码的一些前提知识点： 上面这些参考链接，都可以看看，希尔密码的加解密都会涉及到这些。 对于维基百科的东西，建议都看英文版，中文版写得太烂，完全不知道写的啥玩意儿。 2. 希尔密码的加密. 先来学习希尔密码的加密步骤。 在加密开始之 …

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... 一串字母当成n维向量，跟一个n×n的矩阵相乘，再将得出的结果MOD26。

2021年7月21日 · Hill cipher is a polygraphic substitution cipher based on linear algebra.Each letter is represented by a number modulo 26. Often the simple scheme A = 0, B = 1, …, Z = 25 is used, but this is not an essential feature of the cipher.

Invented by Lester S. Hill in 1929, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Hill used matrices and matrix multiplication to mix up the plaintext.

Hill Cipher is based on linear algebra, advanced matrices (matrix multiplication and matrix inverses), and modulo arithmetic principles. Obviously, it is a more mathematical cipher than others. Hill Cipher is also a block cipher. A block cipher uses a deterministic algorithm and a symmetric key to encrypt a block of text.
