Access Control in IoT using Hyperledger Fabrics Blockchain for Temperature, Humidity, and Pressure

Abstract

IoT system is widely used in industry and gives many benefits to the user. It helps a lot with monitoring and provides real-time information from sensors to the main node. While the IoT brings benefit, it also has its risks, vulnerabilities, and weaknesses. Based on these flaws, it can potentially be manipulated by the hackers to access and deny the services of the IoT system. Having access control through Hyperledger Fabrics Blockchain, it provides a permission blockchain framework that allows only registered devices or sensors to communicate and store the sensor data, which is temperature, humidity, and pressure. This paper will describe generally the integration of IoT using Sense Hat emulator and Hyperledger Fabrics Blockchain setup to show only the legitimate sensors are allowed to be stored in the ledger. In this study, it shows that access control can be managed using blockchain, especially for IoT, which have lacks resources to manage the traditional access control.
