GFpMul_PE

Multiplies an element of the finite field and an element of its parent field.

Syntax

IppStatus ippsGFpMul_PE(const IppsGFpElement*
pA
, const IppsGFpElement*
pParentB
, IppsGFpElement*
pR
, IppsGFpState*
pGFp
);

ippcp.h
Parameters
pA
Pointer to the context of the first multiplicand, an element of the finite field.
pParentB
Pointer to the context of the second multiplicand, an element of the parent finite field.
pR
Pointer to the context of the resulting element of the finite field.
pGFp
Pointer to the context of the finite field.
Description
This function computes the product of the element
pA
of the finite field specified by the context
pGFp
and the element
pParentB
of its ground finite field. The following pseudocode represents this operation:
R = A ⋅ B
.
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
IppsGFpState
and
IppsGFpElement
context parameters does not match the operation.
ippStsOutOfRangeErr
Indicates an error condition in the following cases:
  • The element
    pA
    does not belong to the finite field specified by the context
    pGFp
    .
  • The element
    pParentB
    does not belong to the ground field of the finite field specified by the context
    pGFp
    .
ippStsBadArgErr
Indicates an error condition if the context
pGFp
does not specify a prime field.
