Quantum communication is a technology that trans-mits quantum states. Quantum secure direct communication is a promising application because unlike Quantum key distribution, a message can be transmitted directly through a quantum channel. The secrecy capacity of the QSDC protocol can be estimated using the decoy state. However, the secrecy capacity of the practical QSDC protocol is lowered due to the finite-size effect. In this study, we introduce QSDC protocol with an entanglement source and single-photon measurement and we analyze the secrecy capacity considering statistical fluctuation.
