GFPXECMulPointScalar

Adds a point on the elliptic curve over the GF(p^d) field to itself multiple times.

Syntax

IppStatus ippsGFPXECMulPointScalar(const IppsGFPXECPoint *pA, const Ipp32u *pScalar, Ipp32u scalarLen, IppsGFPXECPoint *pR, IppsGFPXECState *pEC);

Parameters

pA	Pointer to the context of the given point on the elliptic curve.
pScalar	Pointer to the data array that stores the scalar.
scalarLen	Length of the scalar.
pR	Pointer to the context of the resulting point on the elliptic curve.
pEC	Pointer to the context of the elliptic curve.

Description

This function is declared in the ippcp.h file. The function computes the coordinates of the elliptic curve point that equals the product of the given point and the scalar. The following pseudocode represents this operation: R = scalar * A.

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.
