This paper proposes a scheme for secure authentication of classical messages with single photons and a hashed function.The security analysis of this scheme is also given,which shows that anyone cannot forge valid message authentication codes (MACs).In addition,the lengths of the authentication key and the MACs are invariable and shorter,in comparison with those presented authentication schemes.Moreover,quantum data storage and entanglement are not required in this scheme.Therefore,this scheme is more efficient and economical.
