With the proliferation of the Internet of Things (IoT) and the ever-increasing number of devices interconnected through it, security has become a paramount concern. In this paper, we introduce an innovative strategy to bolster IoT security through the fusion of Elliptic Curve Cryptography (ECC) and Isogeny-Based Cryptography. Our approach is underpinned by a bespoke algorithm crafted with IoT security in mind. This approach leverages the strengths of both ECC and Isogeny-Based cryptography to not only enhance the efficiency of encryption and decryption but also to fortify the security of IoT systems, as illustrated in the accompanying IoT diagrams—a vital component of this paper. We offer a fundamental implementation centered on the core principles of our security analysis. This approach acts as a foundational framework, laying the groundwork for a more comprehensive examination in future research. Furthermore, our work extends beyond the immediate present, providing a forward-looking perspective on the evolving landscape of IoT security.
