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
);
Include Files
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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
