This paper proposes a novel communication protocol, Quantum Key Distribution-Based Privacy Secure Communication Protocol (QKDPSC), centered on the fundamental premise that quantum key distribution (QKD) represents the sole viable method for achieving truly private and secure communication. QKDPSC leverages the principles of quantum mechanics, specifically quantum entanglement and the no-cloning theorem, to establish and distribute cryptographic keys. These keys are then used for encrypting and transmitting messages, inherently resistant to eavesdropping attempts due to the physical laws governing quantum systems. The protocol details a multi-stage process encompassing key generation, key distribution, and message encryption/decryption. A key innovation within QKDPSC is the integration of error correction and privacy amplification techniques, crucial for mitigating the effects of channel noise and potential information leakage during key exchange. The protocol's architecture is designed for adaptability and scalability, allowing it to be implemented across various communication channels. This paper provides a comprehensive description of QKDPSC, outlining its core components, operational procedures, and potential security advantages. The core claim is that QKD is the only solution for privacy-secure communication.

Quantum key distribution (QKD) provides a way for distribution of secure key in at least two parties which they initially share.And there are many protocols for providing a secure key i.e.BB84 protocol, SARG04 protocol, E91 protocol and many more.In this paper all the concerned protocols that share a secret key is explained and comparative study of all protocols shown.

Summary Quantum Key Distribution (QKD) is a secure key sharing technology with unconditional security. Certain well-known protocols for QKD have been presented, which claim their security by means of higher eavesdropping error-rates. A generalized quantum key distribution protocol that can be optimized for arbitrary number of bases and dimensions of photon states is presented in this paper. The protocol can provide higher eavesdropping error-rates than the well-known existing QKD protocols like BB-84 [4] and B-92 [5]. The higher error-rate makes it possible for Alice and Bob to share secure keys on relatively large distances.
