LIGHTWEIGHT POST-QUANTUM CRYPTOGRAPHY FOR SECURE IOT COMMUNICATION

The rapid growth of Internet of Things (IoT) devices has increased the requirement for secure and efficient communication between resource-constrained devices. Conventional cryptographic algorithms provide effective security against existing computational threats; however, the development of large-scale quantum computers may threaten widely used public-key cryptographic techniques. Post-Quantum Cryptography (PQC) provides cryptographic mechanisms designed to remain secure against attacks from both classical and quantum computers. 
In this paper we propose a lightweight post-quantum cryptographic solution for the safe communication of IoT, taking into account the low computational power, memory and energy availability of IoT devices. The proposed approach focuses on the selection and evaluation of a suitable lightweight PQC mechanism for IoT environments and analysis of important parameters such as execution time, memory consumption, communication overhead and security considerations. The proposed approach can be evaluated in a prototype-based experimental framework under constrained-device conditions. 
The study looks at how post-quantum security can be incorporated into IoT communications, bearing in mind the real world constraints of embedded systems.
Paper proposes a lightweight post-quantum cryptographic solution for secure IoT communication with a specific focus on the constraints of IoT devices in terms of computational power, memory and energy. The paper looks at the selection and evaluation of a suitable lightweight PQC scheme for the IoT context and considers a range of parameters in the analysis including execution time, memory usage, communication overhead and security. A prototype based experimental framework can be used to evaluate the proposed approach under the constraints of a constrained device. The paper shows how post-quantum security can be brought to IoT communication in a practical manner taking into account the realities of the embedded system.
