DLPSet

Sets up domain parameters of the DL-based cryptosystem over GF(p).

Syntax

IppStatus ippsDLPSet(const IppsBigNumState*
pP
, const IppsBigNumState*
pQ
, const IppsBigNumState*
pG
, IppsDLPState*
pCtx
);
Include Files
ippcp.h
Parameters
pP
Pointer to the characteristic
p
of the prime finite field GF(
p
).
pQ
Pointer to the characteristic
q
of the multiplicative subgroup GF(
q
).
pG
Pointer to the generator
G
of the multiplicative subgroup GF(
r
).
pCtx
Pointer to the cryptosystem context.
Description
The function sets up DL-based cryptosystem domain parameters into the cryptosystem context.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsContextMatchErr
Indicates an error condition if the context parameter does not match the operation.
ippStsRangeErr
Indicates an error condition if any of the Big Numbers specified by
pP
,
pR
, and
pG
is too big to be stored in the
IppsDLPState
context.
