A New Secure Quantum Signature Masked Authentication Scheme

This paper proposes a new way of Quantum signature masked authentication, in which both user and certifying authority is needed for generating final signature. Our scheme uses decoy particle to protect key from all the attacks in the transmission process and does not require encryption of each key. The paper also shows that our scheme is protected against impersonation, forgery and outside attack and is more efficient than the other masked schemes existing in quantum cryptography.
