GFpMultiExp

Multiplies exponents of elements of the finite field.

Syntax

IppStatus ippsGFpMultiExp(const IppsGFpElement* const ppElmA[], const IppsBigNumState* const ppE[], int nItems, IppsGFpElement* pElemR, IppsGFpState* pGF, Ipp8u* pScratchBuffer);

Parameters

ppElmA

Pointer to the array of contexts of the finite field elements representing the base of the exponentiation.

ppE

Pointer to the array of the Big Number contexts storing the exponents.

nItems

Number of exponents.

pElemR

Pointer to the context of the resulting element of the finite field.

pGFp

Pointer to the context of the finite field.

pScratchBuffer

Pointer to the scratch buffer.

Description

This function multiplies exponents of elements of the finite field. The finite field is specified by the context pGFp. You can get the size of the scratch buffer by calling the ippsGFpScratchBufferSize function.

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 IppsGFpState, IppsBigNumState, and IppsGFpElement does not match the operation.

ippStsOutOfRangeErr

Indicates an error condition if any of the elements of ppElmA do not belong to the finite field specified by the context pGFp.

ippStsBadArgErr

Indicates an error condition if nItems is less than 1 or greater than 6.
