Crystals kyber cryptographic algorithm for efficient IoT D2d communication

Abstract

Device-to-Device (D2D) communication stands as a pivotal technology revolutionizing conventional base station-to-device (B2D) communication paradigms. It facilitates direct data exchange among Internet of Things (IoT) devices without intermediaries such as servers or cloud services. However, the direct link between devices poses significant security risks, such as data leaks and unauthorized access. In this paper, a novel Secure data Transmission using Crystals Kyber (STUCK) technique has been proposed to secure device-to-device communication efficiently. STUCK encompasses four pivotal phases: token generation, device discovery, link configuration, and secure data transmission, ensuring robust protection against potential security breaches. Leveraging the Crystals Kyber cryptographic technique, STUCK adeptly manages key operations, encrypts and decrypts data, thus ensuring the integrity of data transmission across devices. Experimental validation conducted in MATLAB validates the efficacy of the proposed system, revealing noteworthy performance metrics encompassing processing time, communication overhead, and encryption duration. Comparative analysis demonstrates superior performance of STUCK, showcasing processing time increases of 23.07%, 44.23%, and 65.38% compared to existing techniques such as B-IoMV, LMECC, and QSAP, respectively.
