ECC-Based Lightweight Authentication for Resource-Constrained Devices Leveraging the Edge Node

CPS have undergone significant evolution, integrating computational elements with physical processes to create intelligent, interconnected systems. However, their interconnected nature exposes them to diverse security threats. Authentication emerges as a critical aspect of CPS security, yet traditional methods face limitations, particularly for resource-constrained devices. In this article, we address these challenges by proposing a secure and efficient authentication mechanism based on elliptic curve cryptography. We provide a formal proof of its security using the Mao–Boyd logic and Proverif, ensuring resilience against known attacks. In addition, we compare the performance of the proposed scheme with other established schemes, demonstrating its effectiveness in enhancing CPS security without compromising operational efficiency. Proposed research contributes to the ongoing effort to fortify CPS against evolving cyber threats, fostering safer and more resilient systems for various applications.
