GFpECAddPoint¶
Computes the sum of two points on an elliptic curve.
Syntax¶
IppStatus ippsGFpECAddPoint(const IppsGFpECPoint* pP, const IppsGFpECPoint* pQ, IppsGFpECPoint* pR, IppsGFpECState* pEC);
Include Files¶
ippcp.h
Parameters¶
pA |
Pointer to the context of the first point on the elliptic curve to be added. |
pQ |
Pointer to the context of the second point on the elliptic curve to be added. |
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 computes the coordinates of the elliptic curve point that
is equal to the sum of two given points. The following pseudocode
represents this operation: R = P + Q.
Return Values¶
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified is NULL. |
ippStsContextMatchErr |
Indicates an error condition if any of the specified contexts does not match the operation. |
ippStsOutOfRangeErr |
Indicates an error condition if any of the specified points does not belong to the finite field over which the elliptic curve is initialized. |
