Reply to Comment on ''Quantum secret sharing based on a reusable   Greenberger-Horne -Zeilinger states as secure carriers''
  We show that the criticism of a recent comment \cite{ch2} on the insecurity of a quantum secret sharing protocol proposed in \cite{v2} is based on a misconception about the meaning of security and hence is invalid. The same misconception also appears in another comment of the authors \cite{ch1} on the security of an entangled-based quantum key distribution protocol \cite{zhang,v1}.
