WebWhy is this encryption so called affine? In mathematics, an affine function is defined by addition and multiplication of the variable (often x x) and written f(x)=ax+b f ( x) = a x + b. … WebThen, each number obtained is transformed by an affine function (f (x) = ax + b). "x" is representing the number while "a" and "b" are defined during the encryption. "a" and "b" …

WebAn affine cipher combines the idea of a shift cipher with a multiplicative cipher. In this particular example, we map consecutive letters of the alphabet to consecutive numbers, starting with A=0 (you can also do this cipher differently, and starting with A=1). The user selects two values, a and b.

WebAs hand ciphers, affine ciphers are too complex to be practically applied without the aid of an explicit lookup table. And while one could indeed construct an encryption table using an affine map, doing so would not seem to offer any particular advantage over e.g. the various keyword-based methods actually used in practice.
