WebThe matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible (modulo 26). The cipher can, of course, be adapted to an alphabet with any number of letters; all arithmetic just needs to be done modulo the number of letters instead of modulo 26. The key matrix must be a square matrix. For example: WebThe Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester Hill in 1929, this cipher uses matrices and matrix multiplication to mix up the plaintext. Wikipedia has an excellent example of how this algorithm works.
