This article is part of my AES series AES' Galois field Rijndael (a.k.a AES) uses what is known as a galois field to perform a good deal of its mathematics. This is a special mathematical construct where addition, subtraction, multiplication, and division are redefined, and where there are a limited number of integers in the field. In more detail, Rijndael's galois field only allows an 8 bit numbe
