WebA primitive polynomial is a polynomial that generates all elements of an extension field from a base field. Primitive polynomials are also irreducible polynomials. For any prime or prime power and any positive integer , there exists a primitive polynomial of degree over GF ( … WebIn data communications and cryptography, we can represent binary values as as polynomials in GF(2). These can then be processed with GF(2) arithmetic. A value of \(10011\) can then be represented in a polynomial form as \(x^4+x+1\). Every non-prime value can be reduced to a multiplication of prime numbers. canned chair
