Combining the idea of quantum secure communication and quantum homomorphic signature, we propose a quantum secure communication protocol with signature via EPR pairs, in which the identities of the sender and the recipient could be certified and the integrity of the message transmitted is guaranteed according to their signatures. Comparing with the previous quantum secure communication scheme without signature, our protocol is not only feasible in practice but also can effectively guarantee the reliability and security of the quantum communication. The security of the protocol is analyzed.

A novel protocol of quantum cryptography, called genuine quantum secure communication (GQSC), is proposed by using a new method for local quantum measurement discrimination (LQMD). After secure quantum channel being established, the transmission of secret messages in the GQSC protocol does not require classical channel. Compared with the previous protocols of quantum secure direct communication, the advantage of the present protocol is not only more security, but also higher covert.

This paper proposes a novel secure communication protocol based on Quantum Key Distribution (QKD). The core claim is to design a protocol capable of completely secure key transmission, resisting eavesdropping and manipulation, thereby guaranteeing communication security. The protocol leverages quantum entanglement to facilitate quantum key transmission and employs cryptographic algorithms for key encryption and decryption. Traditional secure communication protocols relying on classical key exchange are vulnerable to attacks. QKD offers a significantly higher level of security. This document details the protocol's architecture, mathematical formulation of the key exchange process, and the security analysis underpinning its design. The focus is on demonstrating a robust system against known classical and quantum attacks, providing a foundation for future secure communication networks. The system is designed for a two-party communication scenario, aiming for maximal security with reasonable complexity.
