GFpExp¶
Raises an element of the finite field to the specified power.
Syntax¶
IppStatus ippsGFpExp(const IppsGFpElement* pA, const IppsBigNumState* pE, IppsGFpElement* pR, IppsGFpState* pGFp, Ipp8u* pScratchBuffer);
Include Files¶
ippcp.h
Parameters¶
pA |
Pointer to the context of the element of the finite field representing the base of the exponentiation. |
pE |
Pointer to the Big Number context storing the exponent. |
pR |
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 raises the element of the finite field to the given
non-negative power. The following pseudocode represents this operation:
R = AE. The finite field is specified by the context pGFp.
You can get the size of the scratch buffer by calling the function
GFpScratchBufferSize.
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, IppsBigNumState, and IppsGFpElement context parameters does not match the operation. |
ippStsOutOfRangeErr |
Indicates an error condition if pA or pR does not belong to the finite field specified by the context pGFp. |
