AI_ECBuildPubKeyAccelTable
62 RSA BSAFE Crypto-C Library Reference Manual
AI_ECBuildPubKeyAccelTable
Purpose:
This AI allows you to build an acceleration table for a public key and the base point to
be used in various elliptic curve (EC) operations. The acceleration values come from a
table that includes values built for the base point, which are the same as those from
AI_ECBuildAcceleratorTable, and additional values built for the public key. This AI
performs at greater speeds than
AI_ECBuildAcceleratorTable for both ECDSA verify
and ECDH Phase 2 operations.
Type of information this allows you to use:
elliptic curve parameters as defined in X9.62 to generate auxiliary data for the
acceleration of elliptic curve operations with base point and public key. Elliptic curve
parameters can be generated through the execution of
AI_ECParamGen.
Format of info supplied to B_SetAlgorithmInfo:
pointer to a B_EC_PARAMS structure:
where
parameterInfoType
must be AI_ECPubKey and
parameterInfoValue
must be an
A_EC_PUBLIC_KEY structure:
Format of info returned by B_GetAlgorithmInfo:
B_GetAlgorithmInfo is not supported with this AI. If called, it will return an error.
