GFpECSetPointRandom#

Sets the coordinates of a point on an elliptic curve to random values.

Syntax#

IppStatus ippsGFpECSetPointRandom(IppsGFpECPoint* pPoint, IppsGFpECState* pEC, IppBitSupplier rndFunc, void* pRndParam, Ipp8u* pScratchBuffer);

Include Files#

ippcp.h

Parameters#

pPoint

Pointer to the IppsGFpECPoint context.

pEC

Pointer to the context of the elliptic curve.

rndFunc

Pesudorandom number generator.

pRndParam

Pointer to the pseudorandom number generator context.

pScratchBuffer

Pointer to the scratch buffer of size produced by ippsGFpECScratchBufferSize.

Description#

This function assigns random values to the coordinates of an elliptic curve point in the IppsGFpECPoint context.

The ippsGFpECScratchBufferSize function should be called with nScalars equal to at least 1 to get the valid pScratchBuffer.

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 any of the context parameters does not match the operation.

ippStsOutOfRangeErr

Indicates an error if the specified point does not belong to the finite field over which the elliptic curve is initialized.
