- Abstract summary: We propose a new theoretical scheme for quantum secure direct communication (QSDC) with user authentication.
The present protocol uses only one orthogonal basis of single-qubit states to encode the secret message.
We discuss the security of the proposed protocol against some common attacks and show that no eaves-dropper can get any information from the quantum and classical channels.

- Abstract: In this paper, we propose a new theoretical scheme for quantum secure direct
communication (QSDC) with user authentication. Different from the previous QSDC
protocols, the present protocol uses only one orthogonal basis of single-qubit
states to encode the secret message. Moreover, this is a one-time and one-way
communication protocol, which uses qubits prepared in a randomly chosen
arbitrary basis, to transmit the secret message. We discuss the security of the
proposed protocol against some common attacks and show that no eaves-dropper
can get any information from the quantum and classical channels. We have also
studied the performance of this protocol under realistic device noise. We have
executed the protocol in IBMQ Armonk device and proposed a repetition code
based protection scheme that requires minimal overhead.

Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state.
In a quantum network, this protocol can be efficiently implemented using a single copy of a N-qubit Greenberger-Horne-Zeilinger (GHZ) state to distil a secure N-user conference key bit.

In the key agreement protocols, an attacker can impersonate a legal user to participate in the negotiation process and eavesdrop the agreement key easily.
This is often overlooked in most quantum key agreement protocols, which makes them insecure in practical implementation.
Considering this problem, the function of authenticating the user's identity is added in the proposed protocol.

Our results show that the RRDPTS protocol can achieve higher secret key rate in comparison with the RRDPS, in the condition of high quantum bit error rate.
