GFpConj

Computes the conjugate of the element of the finite field GF(p²).

Syntax

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

Include Files

ippcp.h

Parameters

pA	Pointer to the context of the finite field element.
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 conjugate of an element of the finite field GF(p²). If the element of the GF(p²) field is the polynomial x + a, the conjugate element is equal to x – a, where a is an element of the ground field GF(p).

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 IppsGFpState and IppsGFpElement context parameters does not match the operation.
ippStsOutOfRangeErr	Indicates an error condition if the element pA does not belong to the finite field specified by the context pGFp.
ippStsBadArgErr	Indicates an error condition if the element pA does not belong to the GF(`p`²) field.
