ABSTRACT

Blockchain is considered an integral part of today’s Internet. Although this technology is originated from cryptography and classical security domain, it was not utilized in the last few decades. Due to the increased security concerns over continuous cyber attacks and fraudulent activities, blockchain is considered to be a feasible solution now-a-days. Simultaneously, the adoption of Internet of Things (IoT) is growing rapidly, which makescyber security more challenging than ever. In this context, this chapter focuses on the key features of IoT architecture and how blockchain can be leveraged towards addressing the cyber security issues. The chapter will be helpful for both academics and industry professionals working in the cyber security.
