Using IDoT Attributes for Secure Power Data Sharing Based on Blockchain Dynamic Access Control

Data collected through devices are stored in a single cloud and processed in Internet of Things (IoT) environment. Because IoT has a limitation of computing and storage space of devices. In order to solve the problem of reliability of centralized system, previous researches have been carried out to link blockchain to the Internet. However, user privacy protection is an indispensable factor for sharing data through the Internet. However, these limitations are not overcome. In this paper, the access control of the user is made flexible and robust through Dynamic Access Control Table (DACT) using the context attribute of IDentity of Things (IDoT). The system proposed in this paper can build a platform to securely share users’ power consumption data in the energy cloud. 1
