DLPSet

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

Syntax

IppStatus ippsDLPSet(const IppsBigNumState* pP, const IppBigNumState* pQ, const IppsBigNumState* pG, IppsDLPState* pCtx);

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.

This function is declared in the ippcp.h file. The function sets up DL-based cryptosystem domain parameters into the cryptosystem context.

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.
