The presence of the Internet of Things (IoT) enables the exponential growth of IoT devices. The IoT commonly involves many limited resources that are incapable of processing classical cryptographic protocols and vulnerable to threats like privacy loss, Distributed Denial of Service (DDoS) Attacks, and quantum computers. One-time passwords (OTPs) are essential in IoT for enhancing security by ensuring single-use authentication codes and preventing unauthorized access while being lightweight, scalable, and suitable for resource-constrained devices. The proposed work is a novel OTP generation scheme designed on isogeny between two Montgomery elliptic curves, such as translation maps and isogeny computed by the V élu formula to provide secure communication. This scheme is secure and lightweight due to the utilization of the Montgomery curve, known for its computational efficiency in elliptic curve operations, to significantly reduce the complexity and increase the speed of OTP generation. The security is proven by the hardness of computational Deffie Hellman (CDH) over elliptic curves and isogenies. Hence, the scheme is lightweight and suitable for use in secure IoT device communications.
