Secure Communication Based On Key Generation With Quantum Reinforcement Learning

Abstract

Data security and secure communication is one of the most important issues of today. In this study, a quantum-based
 method for secure communication is proposed. In the proposed method, the necessary secret key in communication is generated
 locally by each participant through quantum gates. The quantum gates are taught by using quantum reinforcement learning (QRL).
 Proposed study is simulated using the Qiskit library for Python. Proposed study performs the learning action with an accuracy of
 87.95% for 195 gates, 85.47% for 128 gates, 83.59% for 64 gates, 76.25% for 32 gates. As the key size increases, the performance
 of the method increases. The participants don’t share the secret key in the presented method. Thus, the communication becomes
 more secure. In the study, the method is also examined in terms of security. Security analysis shows that the proposed method
 provide secure communication.
