What does "GF(2^32)" mean in this context?

• pbsd 13y ago
  It's the finite field with 2^32 elements. There are several equivalent representations, but we typically work with it as the polynomials with coefficients modulo 2 modulo an irreducible polynomial of degree 32, e.g., x^32 + x^7 + x^3 + x^2 + 1.
