Internet of Things system based on Internet of Things encryption gateway

Abstract

The invention provides an Internet of Things system based on an Internet of Things encryption gateway. The Internet of Things system comprises an intelligent terminal device used for sending to-be-transmitted data to the Internet of Things encryption gateway; the Internet of Things encryption gateway is used for judging whether a protocol supported by the intelligent terminal equipment is an unsafe protocol, if the protocol is the unsafe protocol, refusing to accept data sent by the intelligent terminal equipment, and if the protocol is the safe protocol, analyzing the data sent by the intelligent terminal equipment by using the protocol supported by the intelligent terminal equipment to obtain to-be-transmitted data, sending the to-be-transmitted data to the Internet, or encrypting and signing the to-be-transmitted data, generating processed data, and sending the processed data to the Internet. The Internet is used for transmitting data to be transmitted or processed data; the security platform is used for receiving the to-be-transmitted data or performing signature verification operation on the processed data, performing decryption operation on the processed data to obtain the to-be-transmitted data after the signature verification is passed, and sending the to-be-transmitted data to the service platform; and the service platform is used for processing to-be-transmitted data.

Description

technical field [0001] The invention relates to the field of computers, in particular to an Internet of Things system based on an encrypted gateway of the Internet of Things. Background technique [0002] Deployment of existing industrial control gas systems such as figure 1 As shown, the data communication between the communication module and the management platform is exposed on the public network, and the data collection lacks security protection functions, and it is mainly uploaded in plain text, which is vulnerable to network attacks. [0003] Existing field device gateways often only collect data from one or a type of manufacturer's devices, and may use non-encrypted data transmission methods, which cannot guarantee completeness and greatly compromised compatibility. [0004] From the point of view of the existing large-scale instrumentation data acquisition gateway, it is only a data transmission channel tailored for a certain manufacturer's instrument. When the inst...

Problems solved by technology

Some instruments are network interfaces. In order to isolate them from the public network, it is often necessary to build an isolation network at high cost.
