In the communication network, transmitting messages from source to destination may traverse several intermediate nodes. For a long period of time, multiple authentications and secure communications between the sender and the receiver are needed for us to transmit messages. In the classical field, authentication provides only conditional security and classical channel can not provide secure communication for liar detection. In the quantum field, multiple quantum entanglement pairs can be used for liar detection. In this paper, we design quantum authentication protocol and secure communication protocol by only using quantum channel. These protocols previously share a quantum key distribution to detect the dishonest node. The quantum key distribution can promote authentication and secure communication for achieving higher liar detection probability.

In the wireless communication network, transmitting messages from sender to receiver may traverse several intermediate nodes. Any eavesdropper can attack in the communication channel, and any malicious intermediate node can act as receiver to intercept the message. The secure routing path must solve channel attacks and attacks in the malicious node. In the classical field, the solution of the channel attacks is conditional security and we can not provide secure communication in the routing path from sender to receiver. In the quantum field, the security of the authentication protocol is based on the laws of nature, including no-cloning theorem and quantum teleportation. According to the property of no-cloning theorem and quantum teleportation, we can use the shared quantum entangled particles between communicators for liar detection problem. In the quantum cryptography, the security of the authentication protocol is unconditional security. This paper designs the two-way secure communication protocol, which can set up the secure routing path from sender to receiver. The two-way secure communication protocol includes the sender oriented checking and the receiver oriented checking. By using quantum sharing table, these checking schemes investigate whether the routing path is secure or not. In the beginning, the sender and receiver pre-share a quantum sharing table to detect all the dishonest nodes. The quantum sharing table acts as a quantum key distribution which can not be stolen by any Eve.
The emergence of sixth-generation (6G) networks presents a promising paradigm aimed at meeting stringent quality-of-service (QoS) requirements, thereby paving the way for modern applications such as the metaverse. In contrast, the advent of quantum computers poses a significant threat to the security of such networks. However, the quantum Internet signifies a remarkable advancement in communication technology, harnessing the principles of quantum entanglement and superposition to facilitate unparalleled levels of security and efficient computations. Quantum communication can be achieved through the utilization of quantum entanglement. Through the exchange of entangled pairs between two entities, quantum communication becomes feasible, enabled by the process of quantum teleportation. Given the lossy nature of the channels and the exponential decoherence of the transmitted photons, a set of intermediate nodes can serve as quantum repeaters to perform entanglement swapping and directly entangle two distant nodes. Such quantum repeaters may be malicious and by setting up malicious entanglements, intermediate nodes can jeopardize the confidentiality of the quantum information exchanged between the two communication nodes. Hence, this paper proposes a quantum identity authentication protocol that protects quantum networks from malicious entanglements. Unlike the existing protocols, the proposed quantum authentication protocol does not require periodic refreshments of the shared secret keys. Simulation results demonstrate that the proposed protocol can detect malicious entanglements with a 100% probability after an average of 4 authentication rounds. Moreover, the average number of authentication rounds required to detect an attack is reduced by 69% and 76.5% compared with benchmark protocols.

Quantum authentication protocols can be used to authenticate both quantum messages and classical messages.In this paper, a new quantum authentication protocol of classical messages is proposed.In our protocol, a sequence of Bell states is shared by the message sender and the corresponding receiver.This sequence is used as the authentication key.Four different unitary operations U 0 , U 1 , U 2 and U 3 are used to encode a classical message m and its hash value h(m) into a sequence of Bell states.To authenticate the classical message, the message receiver extracts m and h(m) from the qubits owned by himself/herself, and verifies whether h(m) matches m.The adversary's disturbance to the quantum channel can be detected by checking whether h(m) matches m.The transmitted message has the properties of both secrecy and authentication.Our quantum authentication protocol is secure against message attack and no-message attack.
By using the order rearrangement of the single photon sequence and unitary transformations, a multiparty controlled quantum communication scheme for Carrier Sense Multiple Access with Collision Detection(CSMA/CD) is presented.In this scheme, messages can only be recovered by the receivers with the permission of all controllers.It is shown that the security of messages transformation can be ensured and the performance of the proposed scheme enhances significantly since the collision can be avoided.

A novel approach to secure data transmission, quantum communication draws on fundamental principles of quantum physics. It ensures that the transmitted information is private and accurate. To provide security, quantum networks implement physical constraints such as the no-cloning rule and quantum entanglement. In contrast, computational complexity is employed by classical networks. However, with the proliferation of multiuser quantum networks, identity verification has become more challenging. People with malicious intentions might easily disrupt services in long-distance quantum networks by impersonating legitimate nodes and sharing entangled resources and quantum channels. This highlights the absolute necessity of secure authentication systems tailored to quantum environments. Enhancements to recent quantum authentication systems have been made utilizing techniques that are resistant to quantum computing. Researchers are looking into quantum digital signatures, entanglement-assisted protocols, and quantum key distribution (QKD) authentication to make multi-party communications more secure. In order to prevent attacks where a user establishes a fraudulent identity or account, these strategies can be applied to quantum networks. This study takes a look at current quantum authentication systems and gives them the once-over, focusing on how well they could handle multiple users. The article delves into the evolution of authentication systems to accommodate the distributed model, where nodes can function as senders, receivers, or relays. We aim to strike a compromise between practicality and security in our lightweight, low-latency protocols. Additionally, the paper discusses quantum-specific issues, such as side-channel attacks and device malfunctions, and how authentication techniques can help prevent them. Finally, this study demonstrates that authentication is the critical component of secure quantum communication for multiple users. The most secure quantum key distribution methods are still vulnerable to attacks from inside or outside the system if proper authentication is not in place.
