Quantum Secure Direct Communication with Authentication Expansion Using Single Photons

Jing Yang, Chuan Xi Wang, Ru Zhang

In this paper we propose two quantum secure direct communication (QSDC) protocols with authentication. The authentication key expansion method is introduced to improve the life of the keys with security. In the first scheme, the third party, called Trent is introduced to authenticate the users that participate in the communication. He sends the polarized photons in blocks to authenticate communication parties Alice and Bob using the authentication keys. In the communication process, polarized single photons are used to serve as the carriers, which transmit the secret messages directly. The second QSDC process with authentication between two parties is also discussed.In this paper we propose two quantum secure direct communication (QSDC) protocols with authentication.

Employing Single Photons for Measurement-Device-Independent Quantum Secure Direct Communication With Identity Authentication

Guodong Li, Jiacheng Liu, Qingle Wang +1 more

Quantum secure direct communication (QSDC) enables secure message transmission without needing pre-shared keys. To enhance the practical reliability of QSDC systems, measurement-device-independent (MDI) protocols have emerged, providing robust security in real-world applications. Despite the advantages of MDI protocols, their implementation has not yet accomplished communication using only single photons which are advantageous due to their ease of preparation and transmission. In this letter, by employing single photons, we propose a novel MDI-QSDC protocol with identity authentication. This protocol achieves mutual identity authentication between the communicating parties, Alice and Bob, enabling authenticated Alice to securely transmit her secret message directly to authenticated Bob. Theoretical analysis demonstrates the protocol is resilient to identity and message security threats. Simulations with practical experimental parameters and efficiency analysis highlight its potential in quantum communication.Quantum secure direct communication (QSDC) enables secure message transmission without needing pre-shared keys.

Cryptanalysis of quantum secure direct communication protocol with mutual authentication based on single photons and Bell states

Nayana Das, Goutam Paul

Abstract Recently, Yan et al . proposed a quantum secure direct communication (QSDC) protocol with authentication using single photons and Einstein-Podolsky-Rosen (EPR) pairs ( Yan L. et al ., Comput. Mater. Contin. , 63 (2020) 1297). In this work, we show that the above QSDC protocol is secure neither against intercept-and-resend attack, nor against impersonation attack. With any of these two types of attacks, an eavesdropper can recover the full secret message. We also propose a suitable modification of this protocol, which not only defeats the above attacks, but also resists all other common attacks. Thus, our modified protocol provides an improvement over the existing one in terms of security.Abstract Recently, Yan et al . proposed a quantum secure direct communication (QSDC) protocol with authentication using single photons and Einstein-Podolsky-Rosen (EPR) pairs ( Yan L. et al ., Comput.
