Abstract

Integrated hardware will be heavily utilized in Internet of Things (IoT) settings. Without the input of consumers, the smallest IoT systems will function and interact with one another, but their functions have to be accurate and secure from multiple threats. In this research, we concentrate on a key security concern for embedded devices in an IoT ecosystem and safe software updates. It is proposed to use blockchain technology in the latest firmware update method to safely verify a firmware version, verify the accuracy of firmware, and install the most recent firmware for embedded devices. The proposed system involves an embedded system asking nodes in a blockchain network for a software update and then receiving an answer to see if the firmware is existing or not. The embedded device receives the most recent firmware from a peer-to-peer node network if it is not already installed. The firmware's authenticity, or accuracy of firmware, is verified even if the version is the most recent. The proposed method ensures that the firmware of the embedded system is existing and unaltered. Thus, attacks that target well-known flaws in the software of embedded devices are neutralized.
