Finite Field -- from Wolfram MathWorld

WebConsider the field GF(16 = 24). The polynomial x4 + x3 + 1 has coefficients in GF(2) and is irreducible over that field. Let α be a primitive element of GF(16) which is a root of this polynomial. Since α is primitive, it has order 15 in GF(16)*. Because 24 ≡ 1 mod 15, we have r = 3 and by the last theorem α, α2, α2 2 and α2 3 In mathematics, a finite field or Galois field (so-named in honor of Évariste Galois) is a field that contains a finite number of elements. As with any field, a finite field is a set on which the operations of multiplication, addition, subtraction and division are defined and satisfy certain basic rules. The most common … See more A finite field is a finite set which is a field; this means that multiplication, addition, subtraction and division (excluding division by zero) are defined and satisfy the rules of arithmetic known as the field axioms. The number of … See more Non-prime fields Given a prime power q = p with p prime and n > 1, the field GF(q) may be explicitly constructed in the following way. One first chooses an irreducible polynomial P in GF(p)[X] of degree n (such an irreducible polynomial always … See more If F is a finite field, a non-constant monic polynomial with coefficients in F is irreducible over F, if it is not the product of two non-constant … See more In cryptography, the difficulty of the discrete logarithm problem in finite fields or in elliptic curves is the basis of several widely used protocols, such as the Diffie–Hellman protocol. For example, in 2014, a secure internet connection to Wikipedia involved the elliptic curve … See more Let q = p be a prime power, and F be the splitting field of the polynomial The uniqueness up to isomorphism of splitting fields implies thus that all fields of order q are isomorphic. Also, if a field F has a field of order q = p as a subfield, its elements are the q … See more The set of non-zero elements in GF(q) is an abelian group under the multiplication, of order q – 1. By Lagrange's theorem, there exists a divisor k of q – 1 such that x = 1 for every non-zero … See more In this section, p is a prime number, and q = p is a power of p. In GF(q), the identity (x + y) = x + y implies that the map Denoting by φ the See more fox news live stream free now
