Supported EC Domain Parameters
The following tables list all pre-defined ECC domain pararmeters. Use the iaik.security.ec.common.ECStandardizedParameterFactory methods to make use of them. You can either provide the curve name (
getParametersByName(name) method
), use the object identifier (
getParametersByOID(oid) method
) or select domain parameters by the key length (
getParametersByBitLength(bits)
method). Some of the curves have more than one name. In this case you can specify any you like.
Supported ECC Domain Parameter for Elliptic Curves over Prime Fields
This is the recommended field type and more efficient in software. The
NIST curves are being used if you initialize the keypair generator just with
the keysize.
