Decentralized Framework for Data Authenticity Protection in IoT Systems
It is predicted that more than 20 billion IoT devices will be deployed worldwide by 2020. These devices form the critical infrastructure to support a variety of important applications, such as smart city, smart grid, and industrial IoT. To guarantee that these applications work properly, it is imperative to authenticate these devices, as well as the data generated by them. Although digital signatures can be applied for these purposes, the scale of the overall system and the limited computation capability of IoT devices pose two big challenges. In order to overcome these obstacles, this paper proposes a novel decentralized ledger-based authentication framework for IoT devices. The framework utilizes a two-layer decentralized ledger architecture together with a lightweight data authentication mechanism to facilitate IoT devices and data management.
