Analysis on issues and challenges of IoT and the solution based on blockchain technology

Abstract

With the development of science and technology, the Internet of Things (IoT) has become an area of great influence and potential. However, the deficient data security and privacy problems of the current IoT systems seriously limit its application. This is due to the fact that the information exchange and data authentication in IoT must be done through the central server. In order to solve the fraud possibility of device, false authentication, unreliable data sharing, eliminating the concept of a central server, the block chain (BC) technology was adopted as part of the Internet of things used to improve the above problems. This paper elaborates the component interaction in the Internet of things which bring security and privacy problems, and introduces the existing block chain technology, the application of Internet of things. Various challenges of IoT and IoT with BC as well as future research directions are summarized.
