Abstract: In computer science, a one-way function is a function that is easy to compute on every input, but hard to invert given the image of a random input. Here, ”easy” and ”hard” are to be understood in the sense of computational complexity theory, specifically the theory of polynomial time problems. Not being one-to-one is not considered sufficient of a function for it to be called one-way (see Theoretical Definition hereinafter), [4]. In classical cryptography, the Hill cipher is a polygraph substitution cipher based on linear algebra, [2, 3]. In this work, we will present an example ...
