A Hybrid Protocol Method Using Noise-Based Switching for Quantum Key Distribution Systems
Quantum Key Distribution is a secure communication method for sharing the encryption key exclusively between known parties. In this work, we present a multi-protocol approach to Quantum Key Distribution by integrating the BB84, SARG04, and E91 protocols. Depending on the noise threshold, the system adaptively switches to the desired protocol in order to optimize the performance of the Quantum Key Distribution system. The simulations are conducted using IBM Qiskit and a comparative analysis of Quantum Bit Error Rate, Secret Key Rate, and Visibility were done for each protocol. The proposed work highlights the reliability and effectiveness of Quantum Key Distribution systems.
