Description
Each of these functions returns a pointer to a structure containing an implementation of arithmetic operations over GF(
q
).
ippsGFpMethod_pArb()
assumes an arbitrary modulus
q
; each of the rest of the functions returns a pointer to the implementation of arithmetic operations over GF(
q
) tailored for a particular
q
. See the table below for the correspondence between method functions and values of the modulus
q
.
