Abstract
The Internet of Things (IoT) plays a significant role in shaping different aspects of our lives. IoT devices have become increasingly important due to their ability to connect, collect, and analyze data, automate processes, improve safety and efficiency, and deliver personalized experiences. However, the advancement in quantum computer development poses a significant threat to resource-constrained IoT devices. This new generation of computers can break the classic public-key cryptographic schemes and digital signatures implemented in these IoT devices. While protecting IoT devices from quantum computer attacks poses many challenges, researchers are continuously making significant progress in developing lightweight post-quantum cryptographic algorithms for efficient key exchange mechanisms and digital signature algorithms tailored to IoT devices to overcome this issue. This paper proposes Q-SECURE, a post-Quantum resistant Security Enhancing Cryptography for Unified Resource-constrained device Encryption. A novel scheme that enables any IoT system to leverage the assistance of other devices in the network to gain the capability to generate any proposed post-quantum cryptographic key of a given size using distributed and parallel computing.
