A Resource-Efficient Quantum Key Distribution Protocol With Multi-User Access And Eavesdropping Detection For Quantum Networks

Abstract

In quantum networks, Quantum Key Distribution (QKD) and the related protocols are distributive to ensure security for end users. Also, attack detection, analyzing security vulnerabilities and performance reduction over high traffic are more challenging which is encountered at multi-user communication end. Existing approaches does not effectually overcome the above given challenges. This research proposed a novel approaches that merges conventional quantum multiple access approaches, QKD and improved security protocols for dealing these issues. Here, a novel Resource-Efficient Quantum Key Distribution (RE-QKD) for establishing communication security among diverse nodes and adopts the conventional quantum multiple accesses. It intends to offer higher speed and scalability during the communication process. Then, security is optimized with RE-QKD that relies on Quantum Access Network to optimize the queries from various end-users. The proposed RE-QKD is proposed to provide security towards the computing attacks and preventing the eavesdropping attack. The proposed model work efficiently and gives promising outcomes with its performance metrics. The proposed RE-QKD model attains 95% detection attack, 97% communication complexity, distributive key rate of 600b/s, 99% computational overhead and 97% communication efficiency. The simulation outcomes shows the reduction in communication complexity up-to 45% and improved detection accuracy which is superior compared to prevailing approaches. The proposed model helps in scalable development and quantum network with better security.
