A Quantum-Inspired Secure Communication Platform with Eavesdropping Detection

Abstract

Secure communication is a critical requirement in modern digital systems, especially with the growing computational capabilities that threaten traditional cryptographic techniques. Quantum Key Distribution (QKD) offers a promising solution by enabling secure key exchange based on the principles of quantum mechanics. This paper presents a simulation-based platform for analyzing a quantum-inspired secure communication framework using the Bennett–Brassard 1984 (BB84) protocol. The proposed system models the processes of quantum bit transmission, basis selection, key generation, and error detection. The performance of the system is evaluated using the Quantum Bit Error Rate (QBER) to identify potential eavesdropping and transmission noise. Experimental results demonstrate that the generated key length increases proportionally with the number of transmitted bits, while approximately half of the bits contribute to the final shared key due to random basis matching. The platform provides an extensible framework for studying quantum-aware security mechanisms and exploring future secure communication systems in the post-quantum era.
