Abstract

The Internet of Things (IoT) refers to a network concept that extends its clients to any item for information exchange and communication. Blockchain is a new application paradigm of distributed data storage, point-to-point transmission, consensus mechanism, asymmetric encryption, intelligent contract and other computer technologies. Blockchain technology for IoT has been a hot topic in academia and industry. This paper mainly summarizes the main existing research results of the challenges faced by IoT, the technical characteristics of blockchain, the advantages of applying blockchain technology in IoT, security challenges (key management, intrusion detection, access control, privacy protection) and the technology to deal with them. Finally, the prospect of this industry would be summarized and discussed. On the basis of this study, we hope to put forward suggestions and provide references for future research orientation.

Keywords: Internet of Things (IoT), blockchain, intrusion detection, access control
