WebApr 17, 2024 · A binary field \mathbb {F}_ {2^n} is composed of binary polynomials modulo a n -degree irreducible polynomial. The multiplication between two elements of \mathbb {F}_ {2^n} is one of the most crucial low-level arithmetic operations. It consists of an ordinary polynomial multiplication and a modular reduction by an irreducible polynomial.
