    "abstract": "A general class of authentication schemes for arbitrary quantum messages is\nproposed. The class is based on the use of sets of unitary quantum operations\nin both transmission and reception, and on appending a quantum tag to the\nquantum message used in transmission. The previous secret between partners\nrequired for any authentication is a classical key. We obtain the minimal\nrequirements on the unitary operations that lead to a probability of failure of\nthe scheme less than one. This failure may be caused by someone performing a\nunitary operation on the message in the channel between the communicating\npartners, or by a potential forger impersonating the transmitter.",
