GFPXExp

Raises an element of the GF(p^d) field to a non-negative power.

Syntax

IppStatus ippsGFPXExp(const IppsGFPXElement *pGFpxElementA, const Ipp32u *pExp, Ipp32u expLen, IppsGFPXElement *pGFpxElementR, IppsGFPXState *pGFpx);

Parameters

pGFpxElementA	Pointer to the context of the GF(`p^d`) element that represents the base of the exponentiation.
pExp	Pointer to the data array that stores the exponent.
expLen	Length of the exponent.
pGFpxElementR	Pointer to the context of the resulting element of the GF(`p^d`) field.
pGFpx	Pointer to the context of the GF(`p^d`) field.

Description

This function is declared in the ippcp.h file. The function raises the element of the GF(p^d) field to the given non-negative power. The following pseudocode represents this operation: R = A^E.

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.
ippContextMatchErr	Indicates an error condition if any of the IppsGFPXState or IppsGFPXElement context parameters does not match the operation.
