Using Blockchain to Improve Security of the Internet of Things

Abstract

The Internet of Things has increased in popularity in recent years, with daily life now being surrounded by “smart devices.” This network of smart devices, such as thermostats, refrigerators, and even stationary bikes affords us convenience, but at a cost. Security measures are typically inferior on these devices; considering that they collect our data around the clock, this is a big reason for concern. Recent research shows that blockchain technology may be one way to address these security concerns. This paper discusses the Internet of Things and the current issues with how security is handled, discusses how blockchain can shore up some of these shortcomings, and goes in depth into examples of how blockchain has been implemented to improve the security of the Internet of Things.
