Context: Key management among large-scale networks is still a challenging issue considering the limited information about adversaries (whether quantum or classical). One solution for such an issue is to use quantuminspired to which refers to a technology, an algorithm, or a strategy that uses conventional computers to execute quantum physics concepts. These techniques make an effort to imitate particular quantum computing properties, such as superposition, entanglement, or quantum parallelism, in order to more effectively or creatively handle particular issues. It can provide security against all types of intruders. Objectives: In this article, inspired by Quantum Key Distribution, we proposed a key-management protocol for enhancing the security and reliability of the network. Two major objectives have been taken into consideration during the proposal of QLSN (proposed protocol), (i) reduced risk if the network needs to transfer the long keys and (ii) a reliable network to transmit the information safely. Methods: (i) QLSN is proposed in the place of the classical Diffie–Hellman key exchange algorithm, which makes it secure against attacks during the transmission of data through the IPSec tunnel. (ii) Risk Analysis is performed on 1-bit, 2 bits, 15 bits, and 50 bits sizes of data. Data transmission is tested for risk analysis and the probability of attacks is checked under different scenarios. Results: The simulation results illustrated the better performance of the proposed protocol in different scenarios with large-scale networks compared to the existing Diffie–Hellman key exchange used in the IPSec protocol proposed by CISCO. Using quantum algorithms and processing advantages, quantum adversaries may be able to take advantage of weaknesses in conventional security systems. Conclusion: An essential step in determining and validating the viability of proposed protocol inside a quantum computing framework is the integration of a QLSN protocol into the IBM Qiskit simulator. By addressing pressing concerns, this validation approach clarifies the performance and security consequences of large-scale networks. Looking ahead, the fusion of artificial intelligence and quantum computing promises fresh methods for key management that will improve network security. In addition, Turing machines–classical computing tools that bridge the gap between the classical and quantum computing paradigms–will continue to play crucial roles in the complex world of large-scale networks
