Investigation of System Performance of Quantum Cryptography Key Distribution in Network Security

For the past decade progress in quantum cryptography changed the status of quantum key distribution (QKD) from laboratory to the practical innovation technology. Quantum cryptography is an emerging technology in which two parties can secure network communications by applying the phenomena of quantum physics. Quantum cryptography applies the uncertainty principle and the no-cloning theorem of quantum mechanics to provide ultra-secure encryption key distribution between two parties. Conventional secret-key cryptography techniques require the communication of a secret key prior to message exchange, and does not detect eavesdropping, and quantum principles can be used to detect eavesdropping probabilistically when it occurs. But there are challenges, and limitations to implement practical quantum cryptography such as detector performance for measuring photons, or optical sources which, enforce by the state-ofthe-art components crucial for the system performance of quantum cryptography, and fiber optical distance range affect the system performance of quantum cryptography For that reason, the goal of this research is to investigate the system performance of quantum cryptography key distribution in network security, and this investigation develops a theoretical integrated research model or conceptual model framework concerning (figure 4) parameters which affect QKD system performance, and generates a key that affects by those variables. To support the research the experimental data are performed, collected, and analyzed at MagiQ Technology in the Research & Development Lab. The rate of cryptography key or sifted key rate and the quantum bit error rate (QBER) are used to gauge the performance. The research presents a guideline to improve the system performance of the quantum cryptography. Keywords-component; Quantum Crytography, QKD System Performance; System Conceptual Model;
