GFpECBindGxyTblStd
Enables the use of base point-based pre-computed tables in kernels performing scalar*Point multiplication.
Syntax
IppStatus ippsGFpECBindGxyTblStd192r1(IppsGFpECState* pEC);
IppStatus ippsGFpECBindGxyTblStd224r1(IppsGFpECState* pEC);
IppStatus ippsGFpECBindGxyTblStd256r1(IppsGFpECState* pEC);
IppStatus ippsGFpECBindGxyTblStd384r1(IppsGFpECState* pEC);

Parameters
pEC |
Pointer to the cryptosystem context based on a standard elliptic curve |
Description
The functions enable the use of base point-based pre-computed tables in kernels performing scalar*Point multiplication. This will result in the better performance for ippsGFpECSignDSA, ippsGFpECVerifyDSA and ippsGFpECPublicKey public API. The call to these functions should be placed after pEC state is allocated and initialized.
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 the pEC parameter does not match the operation. |
ippStsBadArgErr |
Indicates an error condition if the pEC parameter does not specify the finite field over which the given standard elliptic curve is defined. |
