Application of Blockchain in IoT Data Trust and Information Available Technology
Shuo Liu · 2019
Due to the lack of flexible and effective processing mechanism in the process of data interaction and information transmission in Internet of Things(IoT), this has seriously hindered the process of realizing "interconnection of all things, sharing of all information " in IoT. In order to optimize the above problems, this paper introduces Blockchain technology, and focuses on the analysis of the mapping relationship of Blockchain technology for the hierarchical architecture of IoT. At the perception level of IoT, Merkle tree technology is used to realize the encryption and security of data; at the network level of IoT, the consensus mechanism for the correct use of the information is compared and analyzed. Based on the preliminary discussion of the application of the above Blockchain technology in IoT, the development trend of " IoT+Blockchain" technology in the future is conceived.
