Abstract
Internet of Things (IoT) device security is one of the crucial topics in the field of information security. IoT devices are often protected securely through firmware update. Traditional update methods have their shortcomings, such as bandwidth limitation and being attackers’ easy targets. Although many scholars proposed a variety of methods that are based on the blockchain technology to update the firmware, there are still demerits existing in their schemes, including large storage space and centralized stored firmware. In summary, this research proposes a highly secure and efficient protection mechanism that is based on the blockchain technology to improve the above disadvantages. Therefore, this study can reduce the need of storage space and improve system security. The proposed system has good performance in some events, including firmware integrity, security of IoT device connection, system security, and device anonymity. Furthermore, we confirm the high security and practical feasibility of the proposed system by comparing with the existing methods.
Highlights
The above-mentioned features can be compared among different blockchain platforms, and we find Ethereum is superior to others
Evaluation of Experimental firmware update file, so and that Comparison the devices can be protected from being exposed to a dangerous environment

Summary
IoT devices are often protected securely through firmware update. Many scholars proposed a variety of methods that are based on the blockchain technology to update the firmware, there are still demerits existing in their schemes, including large storage space and centralized stored firmware. This research proposes a highly secure and efficient protection mechanism that is based on the blockchain technology to improve the above disadvantages. The proposed system has good performance in some events, including firmware integrity, security of IoT device connection, system security, and device anonymity. The increasing popularity of IoT devices has been accompanied by several challenges, including security and update service availability. IoT devices are mostly less secure than personal computers with many protection mechanisms, so they often become the target of hackers [1].
