A finite field k = 𝕗 Mod p (be sure its a prime, just fermat prime test here, so avoid carmichael numbers) a: Generate random polynomials of various field sizes and add/multiply them, as well as simplify coefficients and project the polynomial into a different.

Also Called Galois Fields, Finite Fields Are Often Used In Cryptography.

Here is an image that shows how to do everything you requested in your question with a general finite field: Binary values expressed as polynomials in gf(2 m) can readily be manipulated using the definition of this finite field. Y2+y= 3∗x3+2∗x2+x+1 mod 53 y 2 + y = 3 ∗ x 3 + 2 ∗ x 2 + x + 1 mod 53 x2 =y2 mod 109 x 2 = y 2 mod.

In Mathematics, Finite Field Arithmetic Is Arithmetic In A Finite Field Contrary To Arithmetic In A Field With An Infinite Number Of Elements, Like The Field Of Rational Numbers.

Then r ( x) can be obtained by substitute q ( x) back to the equation (1). So f f has four elements, and in fact it is not hard to check that f f is a field. Now (λ+1)8+ (λ+1)4+ (λ+1)3+ (λ+1)2+ 1 = λ8+ λ4+ λ3+ λ+ 1 = 0.
