GFpECMulPoint¶
Multiplies a point on an elliptic curve by a scalar.
Syntax¶
IppStatus ippsGFpECMulPoint(const IppsGFpECPoint* pP, const IppsBigNumState* pN, IppsGFpECPoint* pR, IppsGFpECState* pEC, Ipp8u* pScratchBuffer);
Include Files¶
ippcp.h
Parameters¶
pP |
Pointer to the context of the given point on the elliptic curve. |
pN |
Pointer to the Big Number context storing the scalar value. |
pR |
Pointer to the context of the resulting point on the elliptic curve. |
pEC |
Pointer to the context of the elliptic curve. |
pScratchBuffer |
Pointer to the scratch buffer. Can be NULL. |
Description¶
This function computes the coordinates of the elliptic curve point that
equals the product of the given point and a scalar. The following
pseudocode represents this operation: R = scalar ⋅ P.
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 specified contexts does not match the operation. |
ippStsOutOfRangeErr |
Indicates an error condition in the following cases:
