Abstract

As Internet-of-Things (IoT) infrastructure has significantly dominated our life such as smart homes, hospitals, vehicles, and farms, efficient and secure IoT data management have been a new challenge to handle massive volumes of data and a myriad of IoT devices. To solve these problems, blockchain has become a critical technology to create a decentralized and publicly accessible network for immutable and verifiable data transaction for IoT. This paper proposes an efficient and secure data management system by using the blockchain technology to issue certificates for IoT devices and to retrieve data by using the certificates in any locations. The certified IoT devices in blockchain provide user privacy and data integrity for users while giving efficient data storage and retrieval through our blockchain-based IoT certificate management system. The certificates issued to the IoT devices hold data generated by the device and store it on the blockchain. We evaluate our proposed system on Ethereum to measure transaction cost and speed by issuing and verifying certificates according to the amount of data stored.
