Currently, hyperelliptic curve cryptography (HECC) got attractions towards low power devices such as Industrial Internet of things (IIoT). As we all know, it has the capability of utilizing low key size, which can be suitable for IIoTenvironment. Inspired by the aforementioned property of HECC, we proposed an efficient scheme for IIoT using certificateless signature with the help of HECC. the presented approach is proven to be unforgeable against the challenges of type I and type II attackers. We tested the security of the designed approach through Automated Validation of Internet Security Protocols and Applications (AVISPA). We also performed the computational and communicational cost comparisons with already existed schemes, and it is observed from our analysis that our scheme is computationally efficient and needs low communication cost.
1. Introduction
Internet of Things (IoT) is a network of physical interconnected devices, which incorporate embedded technologies such as RFID, sensors, and other smart devices [1, 2], networked together for communicating with the external environments via the Internet [3, 4]. On the other hand, IoT is growing its scope through linking cities to mature smart systems. these smart systems are designed to combine our routine items with smart devices to create a fully automated intelligent system (AIS) that has the potential to reduce human effort. According to a recent Ericsson report, about 18 billion smart IoT devices will be connected to the Internet by 2022 [5]. This new innovative trend has paved the way for integrating these innovative technologies into various fields such as healthcare, data mining, transportation, and commerce [6–10]. Since its first proposal [11], IoT has attained considerable admiration among the research community in both pedagogy and industries [12].
9. Conclusion
this study presents an efficient scheme for IIoT using certificateless signature with the help of the hyperelliptic curve cryptosystem (HCC). the presented approach is proven to be unforgeable against the challenges of type I and type II attackers. the security of the proposed work is tested through a popular tool “AVISPA.” A comprehensive comparative analysis against relevant schemes has been given which shows how our proposed scheme is better in terms of both communication and computation costs from them. Based on the above claims, we argue that the designed scheme will be the best option for the resource-limited devices in terms of cost consumptions.
