Detailed Description

Member context interface.

Function Documentation

EpidStatus EpidComputePreSig	(	MemberCtx const *	ctx,
		PreComputedSignature *	precompsig
	)

Performs Pre-computation that can be used to speed up signing.

Warning

Do not re-use the same pre-computed signature to generate more than one signature. If a pre-computed signature is used for computing two signatures, an attacker could learn the Intel(R) EPID private key.

Parameters

[in]	ctx	The member context.
[out]	precompsig	The pre-computed signature.

Returns

EpidStatus
