WebDec 6, 2024 · The 2 m elements of GF 2 m are usually represented by the 2 m polynomials of a degrees less than m with binary coefficients. Such a polynomial can either be specified by storing the coefficients in a BIGNUM object, using the m lowest bits with bit numbers corresponding to degrees, or by storing the degrees that have coefficients of 1 in an ...

WebDec 12, 2024 · A primitive irreducible polynomial generates all the unique 2 4 = 16 elements of the field GF (2 4). However, the non-primitive polynomial will not generate all the 16 unique elements. Both the primitive polynomials r 1 (x) and r 2 (x) are applicable for the GF (2 4) field generation.
