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
.Function | Value of modulus q |
|---|---|
ippsGFpMethod_p192r1() | q = 2192 - 264 - 1 |
ippsGFpMethod_p224r1() | q = 2224 - 296 - 1 |
ippsGFpMethod_p256r1() | q = 2256 - 2224 + 2192 + 296 - 1 |
ippsGFpMethod_p384r1() | q = 2384 - 2128 - 296 + 232 - 1 |
ippsGFpMethod_p521r1() | q = 2521 - 1 |
ippsGFpMethod_p256sm2() | q = 2256 - 2224 - 296 + 264 - 1 |
ippsGFpMethod_pArb() | Arbitrary modulus q |
