Quantum Key Distribution (QKD) can be characterized as the revolutionary method of ensuring security in the course of the information exchange and it is based on the principles of quantum mechanics. This research presents a new QKD protocol for the future generation network solving significant issues concerning security and scalability. The designed protocol employs sophisticated methods that promote character distribution effectiveness, reduce error frequency, and integrate the investigated system into obtainable systems. In practical experiments and with the help of numerous simulations, the authors prove that the discussed protocol outperforms existing approaches and can be efficiently used in large networks and even the Internet. These results present a feasible and efficient approach for the improvement of communication security with the emerging potentials of Next Generation Networks and their role with the development of quantum cryptography and its incorporation into contemporary communication structures.

As the limitations of classical cryptographic systems become increasingly evident in the face of advancing quantum algorithms, Quantum Key Distribution (QKD) emerges as a vital paradigm for securing information in next-generation networks. This paper explores the theoretical foundations and protocol architectures underpinning QKD, including BB84, E91, and newer hybrid approaches designed for scalable integration into existing infrastructures. Performance metrics such as key generation rate, error thresholds, and resistance to various attack models are critically examined across both fiber-optic and free-space implementations. Furthermore, the study delves into real-world deployment challenges—ranging from synchronization errors and quantum channel noise to cost-efficiency and interoperability with classical systems. By offering a comparative analysis and proposing optimization strategies, this work aims to pave the way for robust quantum-secure communication protocols suited for large-scale, heterogeneous network environments.

The current development of quantum computing threatens the security of conventional encryption algorithms such as RSA. In recent years, Quantum Key Distribution (QKD) has introduced to the world of information security a viable method that is anticipated to provide security protection against the threat of quantum computing. In this paper, we investigate the protocols of the QKD system. Next, we focus on an experimental study of quantum key distribution. A physical QKD system is leveraged to assist us in further investigating quantum key distribution processes. In our study, an eavesdropper was evaluated to analyze the impact on the QKD processes. In the experimental study results, the difference in key generation, exchange, and error rates between normal and attack scenarios can be observed.
