Device-Independent Quantum Secure Direct Communication with User Authentication. (arXiv:2304.03201v1 [quant-ph])

Quantum Secure Direct Communication (QSDC) is an important branch of quantum
cryptography, which enables the secure transmission of messages without prior
key encryption. However, traditional quantum communication protocols rely on
the security and trustworthiness of the devices employed to implement the
protocols, which can be susceptible to attacks. Device-independent (DI) quantum
protocols, on the other hand, aim to secure quantum communication independent
of the devices used by leveraging fundamental principles of quantum mechanics.
In this research paper, we introduce the …
