Galois Fields — GF(2^n)
In 1831, Évariste Galois died of duelling wounds at the age of 20 but left a great legacy. While he was a teenager he worked on polynomials and laid down the principles of Galois theory, along with defining the concept of a finite field. In cryptography, the finite field is one of the major concepts and involves limiting the number of possible values to a limiting factor (p). The values of the field then range from 0 to p-1.
