GFpECSetPointRandom

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

Syntax

IppStatus ippsGFpECSetPointRandom(IppsGFpECPoint*

, 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.
Description
This function assigns random values to the coordinates of an elliptic curve point in the
IppsGFpECPoint
context.
If the pointer to the scratch buffer is
NULL
, the function uses a short internal buffer for computations.
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.
