GFPXECVerifyPoint

Verifies whether the point belongs to the elliptic curve over the GF(p^d) field.

Syntax

IppStatus ippsGFPXECVerifyPoint(const IppsGFPXECPoint *pPoint, IppsECResult *result, IppsGFPXECState *pEC);

Parameters

pPoint	Pointer to the context of the elliptic curve point.
result	The result of the verification.
pEC	Pointer to the context of the elliptic curve.

Description

This function is declared in the ippcp.h file. The function verifies whether the given point belongs to the elliptic curve over the GF(p^d) field. The result of the verification is returned in *result and can have the following values:

ippECValid	The point belongs to the curve.
ippECPointIsNotValid	The point does not belong to the curve.

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.
