摘要:Most of the quantum authentication protocols are used to authenticate quantum messages. In this paper, by using a pair of non-entangled qubits, a quantum authentication protocol of classical messages is proposed. In the pair of qubits, the first one is used to carry a bit message, and the second one is used as a tag to authenticate the classical message. In our protocol, a bit string instead of a sequence of maximally entangled states is used directly as an authentication key, so the authentication key can be easily stored offline. On the other hand, in our protocol, a unitary operation U A is chosen to encrypt the qubits so that the successful probability of all attacks analyzed is less than one. Our quantum authentication protocol is secure against various attacks such as the no-message attack and message attacks.
