Detailed Description

template<class INTERFACE, class KEY_INTERFACE>
class DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >

Discrete Log (DL) signature scheme base implementation.

Template Parameters

INTERFACE	PK_Signer or PK_Verifier derived class
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 INTERFACE, class KEY_INTERFACE>

size_t DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::SignatureLength ( ) const

inline

Provides the signature length.

Returns

signature length, in bytes

SignatureLength returns the size required for r+s.

Definition at line 1400 of file pubkey.h.

MaxRecoverableLength()

template<class INTERFACE, class KEY_INTERFACE>

size_t DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::MaxRecoverableLength ( ) const

inline

Provides the maximum recoverable length.

Returns

maximum recoverable length, in bytes

Definition at line 1408 of file pubkey.h.

MaxRecoverableLengthFromSignatureLength()

template<class INTERFACE, class KEY_INTERFACE>

size_t DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::MaxRecoverableLengthFromSignatureLength ( size_t  signatureLength ) const

inline

Provides the maximum recoverable length.

Parameters

signatureLength

the size fo the signature

Returns

maximum recoverable length based on signature length, in bytes

this function is not implemented and always returns 0.

Definition at line 1415 of file pubkey.h.

IsProbabilistic()

template<class INTERFACE, class KEY_INTERFACE>

bool DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::IsProbabilistic ( ) const

inline

Determines if the scheme is probabilistic.

Returns

true if the scheme is probabilistic, false otherwise

Definition at line 1420 of file pubkey.h.

AllowNonrecoverablePart()

template<class INTERFACE, class KEY_INTERFACE>

bool DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::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 1425 of file pubkey.h.

RecoverablePartFirst()

template<class INTERFACE, class KEY_INTERFACE>

bool DL_SignatureSchemeBase< INTERFACE, KEY_INTERFACE >::RecoverablePartFirst ( ) const

inline

Determines if the scheme allows recoverable part first.

Returns

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