Problems solved by technology

[0003] At present, there are more and more smart devices connected to the Internet of Things, the number of devices is increasing rapidly, and the scale of applications is getting larger and larger. The cloud server-centered approach currently adopted, and the infrastructure costs and maintenance costs of the data center continue to increase. It is vulnerable to centralized malicious attacks. The cloud server database stores all data. Once an exception occurs, data loss will cause great losses, and the data is easy to be tampered with. The current wireless sensor network is very vulnerable to attacks. Data transmission Data is easy to leak, IoT devices are easy to be controlled, user data privacy is difficult to guarantee, data is easy to be tampered with during transmission, and data obtained by sensors is difficult to share
