A simple substitution cipher takes each vector () and assigns it to the vectors [
] in a one-to-one function so as to make them equivalent.
In 1929, the Hill cipher was invented by Lester S. Hill and it can be described as a poly-graphic substitution cipher that is typically based on linear algebra and it avails a cryptographer an ability to simultaneously operate on more than three (3) symbols.
In Cryptography, the simple substitution cipher is usually viewed as a function which takes each plaintext letter (alphabet) and assigns it to a ciphertext letter. Thus, it takes each vector () and assigns it to the vectors [
] in a one-to-one function so as to make them equivalent.
