Abstract

Traditional encryption techniques face serious threats from the rapid development of quantum computing, which could soon compromise many classical algorithms. To address this, new quantum-resistant security methods are needed to protect private data and communications. This paper proposes a hybrid encryption approach that integrates quantum key distribution (QKD) with a simplified 3×3 advanced encryption standard (AES) key matrix, creating a lightweight system. The objective is to provide an efficient encryption method suitable for devices with limited processing power, such as IoT devices. The model was simulated using Qiskit, achieving an average quantum bit error rate of 0.00%, protocol efficiency of 49.72 %, and quantum fidelity of 1.000 under certain conditions. During eavesdropping scenarios, the error rate increased to 16.90 %. The simplified AES achieved a 50.14 % avalanche effect and an encryption time of 0.3073 ms, reducing latency by 17 % compared to standard AES. These results suggest that combining QKD with lightweight AES can provide quantum resilience and computational efficiency, offering a practical solution for secure communication in the post-quantum era.
