WebMar 15, 2014 · The galois field arithmetic involves addition, multiplication, squaring and inversion in galois field. The trapdoor function is achieved by the scalar point multiplication.The strength of ECC security comes from the difficulty of Elliptic Curve Discrete Logarithm Problem. WebBecause every finite field of a given size is equivalent, any field with 256 elements always has the same universal properties. Galois, who died at age 20 in the chaos of post-Napoleon France, blazed the mathematical trail to much of this area, so we call the field with 256 elements GF(2 8), or "Galois Field with 2 8 elements".
