Member Function Documentation

template<unsigned int NumT, unsigned int ThreshT> const ShareType::ValueType& CODEX_VSS::ShareSet< Combinatoric< NumT, ThreshT > >::operator() (  unsigned int    i )  const [inline]

The share for a given index. Parameters: i  The index of a share. Returns: The corresponding share, which is uninitialized if that share is not held locally. Exceptions: CODEX_Exceptions::IllegalIndexException  if the index is out of range. Definition at line 494 of file Combinatoric.h.

template<unsigned int NumT, unsigned int ThreshT> void CODEX_VSS::ShareSet< Combinatoric< NumT, ThreshT > >::recover (  CODEX_ASN1::SecureBigNumber &    result )  const [inline]

Recover the secret from the set of shares. Parameters: result  The recovered secret, uninitialized if not enough shares are present in the set. Definition at line 524 of file Combinatoric.h.

template<unsigned int NumT, unsigned int ThreshT> void CODEX_VSS::ShareSet< Combinatoric< NumT, ThreshT > >::setShare (  unsigned int    i, const typename ShareType::ValueType &    share )  [inline]

Set the share at a given index to a particular value. Parameters: i  The index of a share. share  The value to which the share should be set. Exceptions: CODEX_Exceptions::IllegalIndexException  if the index is out of range. Definition at line 507 of file Combinatoric.h.

template<unsigned int NumT, unsigned int ThreshT> bool CODEX_VSS::ShareSet< Combinatoric< NumT, ThreshT > >::shouldHave (  unsigned int    shareNum, unsigned int    partNum )  const [inline]

Test whether a participant in a secret sharing scheme should have a particular share index. Parameters: shareNum  The index of a share. partNum  The identifier of a participant. Returns: Whether or not the participant should have this share. Exceptions: CODEX_Exceptions::IllegalIndexException  if either parameter is out of the valid range.
