ECCPMulPointScalar

Performs scalar multiplication of a point on the elliptic curve defined over GF(p).

Syntax

IppStatus ippsECCPMulPointScalar(const IppsECCPPointState* pP, const IppsBigNumState* pK, IppsECCPPointState* pR, IppsECCPState* pECC);

ippcp.h

Parameters

pP

Pointer to the elliptic curve point P.

pK

Pointer to the scalar K.

pR

Pointer to the elliptic curve point R.

pECC

Pointer to the context of the elliptic cryptosystem.

Description

The function performs the K scalar multiplication of an elliptic curve point P over GF(p) with the result in a point R such that R = K· P.

The elliptic curve domain parameters must be hitherto defined by one of the functions: ECCPSet or ECCPSetStd.

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 one of the contexts pointed by pP, pK, pR, or pECC is not valid.
