Enhancing vehicle IoT security through matrix power functions in supertropical semiring

Abstract

The growing ecosystem of Internet of Things (IoT) devices in the automotive industry demands innovative solutions for secure communication and data exchange. In this context, we present a novel lightweight symmetric key exchange protocol based on matrix power functions, employing the supertropical semiring as a platform. This protocol offers a unique and robust approach to ensuring the confidentiality and integrity of data transmission in Vehicle IoT (VIoT) devices. In this paper, we detail the theoretical foundations of our protocol, explaining the mathematics behind supertropical semirings. We also describe the algorithm of key exchange process, highlighting its efficiency and security features. Furthermore, we demonstrate the feasibility and performance of our protocol through extensive simulations and experimentation analysis.
