Abstract
Highlights
Internet of things technology is the future of connecting different devices, places and organizations for data analysis and device control. So, researchers turn to develop communication security for IOT. In the environment of the IoT, the number of heterogeneous terminal connections and the amount of data transmission are very large. The entry of blockchain can solve the existing problems of IoT security. In this paper we, show the previous work in this field to show the advantages and disadvantages of applying blockchain on IOT platform. This clarifies a big picture of combination between IOT and blockchain. From the comparison of the previous algorithms, we find that the decentralized architecture of blockchain reduces the pressure of the old central computing of the IoT, and provides more possibilities for the innovation of the organizational structure of the IoT.
Keywords
Internet of Things (IoT) technology is used in different devices to interconnect each other and transfer data over the Internet for the purpose of remote control automatically. IOT leads to the creation and improvement of operations in the field of activities that contribute to increasing business, increase profitability and new opportunities for enterprises in activities related to solutions and innovations [1]. However, IOT platform faces many challenges.
One of challenges that faces the IoT platform is data protection issue. Because the specifications of IOT
we present, in Section 2, overviews covering IoT technology . in Section 3, we present and discuss Blockchain technology ,its functions, nodes, and types. In Section 4, presents related work of blockchain for IoT.
