GFpxMethod

Returns a reference to the implementation of arithmetic operations over GF(p
d
).

Syntax

const IppsGFpMethod* ippsGFpxMethod_com(void
);
const IppsGFpMethod* ippsGFpxMethod_binom2(void
);
const IppsGFpMethod* ippsGFpxMethod_binom3(void
);
const IppsGFpMethod* ippsGFpxMethod_binom(void
);

Description
Each of these functions returns a pointer to a structure containing an implementation of arithmetic operations over GF(
p
d
).
ippsGFpxMethod_com
 assumes an arbitrary value of the field polynomial
g
(
x
); each of the rest of the functions returns a pointer to the implementation of arithmetic operations over GF(
p
d
) tailored for a particular value of
g
(
x
). See the table below for the correspondence between method functions and values of the field polynomial
g
(
x
).
ippsGFpxMethod_binom2_epid2()
 and
ippsGFpxMethod_binom3_epid2()
 are designed especially for the construction of finite field extensions for applications that use the Intel® Enhanced Privacy ID 2.0 scheme.
