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(p2) field. |
