A simple substitution cipher takes each vector ([tex]e_i[/tex]) and assigns it to the vectors [[tex]e_{\pi (i)}[/tex]] in a one-to-one function so as to make them equivalent.
What is the Hill cipher?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 ([tex]e_i[/tex]) and assigns it to the vectors [[tex]e_{\pi (i)}[/tex]] in a one-to-one function so as to make them equivalent.
