Detailed Description

template<class INTFACE, class KEY_INTFACE>
class DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >

Discrete Log (DL) signature scheme base implementation.

Template Parameters

INTFACE	PK_Signer or PK_Verifier derived class
KEY_INTFACE	DL_Base key base used in the scheme

DL_SignatureSchemeBase provides common functions for signers and verifiers. DL_Base<DL_PrivateKey> is used for signers, and DL_Base<DL_PublicKey> is used for verifiers.

Member Function Documentation

SignatureLength()

template<class INTFACE , class KEY_INTFACE >

size_t DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::SignatureLength ( ) const

inline

Provides the signature length.

Returns

signature length, in bytes

SignatureLength returns the size required for r+s.

Definition at line 1550 of file pubkey.h.

MaxRecoverableLength()

template<class INTFACE , class KEY_INTFACE >

size_t DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::MaxRecoverableLength ( ) const

inline

Provides the maximum recoverable length.

Returns

maximum recoverable length, in bytes

Definition at line 1558 of file pubkey.h.

MaxRecoverableLengthFromSignatureLength()

template<class INTFACE , class KEY_INTFACE >

size_t DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::MaxRecoverableLengthFromSignatureLength ( size_t  signatureLength ) const

inline

Provides the maximum recoverable length.

Parameters

signatureLength

the size of the signature

Returns

maximum recoverable length based on signature length, in bytes

this function is not implemented and always returns 0.

Definition at line 1565 of file pubkey.h.

IsProbabilistic()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::IsProbabilistic ( ) const

inline

Determines if the scheme is probabilistic.

Returns

true if the scheme is probabilistic, false otherwise

Definition at line 1570 of file pubkey.h.

AllowNonrecoverablePart()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::AllowNonrecoverablePart ( ) const

inline

Determines if the scheme has non-recoverable part.

Returns

true if the message encoding has a non-recoverable part, false otherwise.

Definition at line 1575 of file pubkey.h.

RecoverablePartFirst()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::RecoverablePartFirst ( ) const

inline

Determines if the scheme allows recoverable part first.

Returns

true if the message encoding allows the recoverable part, false otherwise.
