摘要：Classical messages can be authenticated by traditional authentication protocols based on hash functions. The security of these protocols depends on long authentication keys, the selection of appropriate hash functions and some assumptions concerning the computational complexity of some algorithms. In this paper, by encoding the classical binary messages and binary keys as nonorthogonal quantum messages and nonorthogonal sets of states, respectively, and using quantum encrypting scheme, a new quantum authentication protocol is proposed. In our protocol, instead of entangled quantum states, the traditional binary bits, which can be easily saved, are encoded as quantum keys. Because the quantum messages are nonorthogonal, any forgery or measurement on the quantum messages will be detected with a certain probability. Our protocol allows the authentication of binary classical messages in a secure manner.
