Abstract

The present invention relates to a data transmission method in an internet of things. Data is transmitted between terminals in an internet of things environment; a transmit end sends original data to network data transmission devices; the network data transmission devices sequentially add a digital signature to each piece of data; and the final network data transmission device verifies all digital signatures of the received data, determines that the data is from the transmit end through a set path, and then sends the original data to a receive end. The present invention further provides a data transmission system in the internet of things and a data transmission apparatus in the internet of things. The data is singed when passing each hardware device in transmission, a later receiving device can verify the signature, so that multiple nodes on one communication chain are managed safely and effectively, the whole communication chain is ensured to communicate safely, and a non-credit person is prevented from intruding and controlling the device.

Description

technical field

[0001] The invention belongs to the field of data transmission, and in particular relates to a data transmission method, system and device in the Internet of Things. Background technique

[0002] The Internet of Things (Internet of Things) is an information carrier based on the Internet and traditional telecommunication networks. It uses technologies such as RFID, wireless data communication, and appropriate information security mechanisms to provide safe, controllable and even personalized real-time online monitoring and positioning. Management and service functions such as traceability, alarm linkage, dispatch command, plan management, remote control, security prevention, remote maintenance, decision support, etc., enable all common physical objects that can be independently addressed to achieve interconnection and interoperability. The integration of "management, control, and operation" of "high efficiency, energy saving, safety, and environmental protecti...
