Two Semi-Quantum Direct Communication Protocols with Mutual Authentication Based on Bell States
In this paper, we proposed two semi-quantum direct communication protocols based on Bell states. By pre-sharing two secret keys between two communicants, Alice with the advanced quantum ability can transmit secret messages to the classical Bob who can only perform the limited classical operations. At the same time, both sides of the communication can comfirm the legitimacy of each other’s identity. Security and qubit efficency analysis have been given. The analysis results show that the two protocols can resistant to several well-known attacks and their qubit efficency is higher than some current protocols.
