Problems solved by technology

[0003] The lack of effective protection for data transmission security between IoT monitoring terminals, especially wireless terminals and IoT monitoring platforms, will bring serious security risks to the IoT monitoring system. Once the attacker intercepts key information, the entire The system intrudes, or maliciously tampers with the data collected by the terminal and modifies the instructions issued by the monitoring platform to the terminal, which brings huge security risks

Embodiment Construction

[0038] The technical solution of the present disclosure will be described in further detail below with reference to the drawings and embodiments.

[0039]In related technologies, it is often necessary for the IoT terminal to encrypt the terminal DUC with the application time and IMEI as the key, and then send it to the platform for registration, and the platform verifies the legitimacy of the terminal DUC. DUC is the displacement code of the IoT terminal equipment, which is unique and corresponds to the IoT monitoring terminal one by one. After the verification is passed, it is sent to the terminal as a key according to the current time, and the terminal uses the received time and the IMEI of the terminal as the key to encrypt the message.

[0040] In such an encrypted communication method, when the terminal uploads a message, the platform can obtain the IMEI code of the terminal communication module, and the attacker can also obtain the IMEI code, so the attacker can also gen...

Abstract

The invention provides an Internet of Things communication method, platform, terminal and system, and relates to the technical field of Internet of Things. The Internet of Things communication methoddisclosed by the invention comprises the following steps: an Internet of Things platform receives an encrypted message from a terminal; a DUC (Device Unique Code) of the terminal is determined based on the association relationship between the IMEI (International Mobile Equipment Identity) and the DUC according to the IMEI of the terminal communication module; and the encrypted message is decryptedby using the DUC to obtain message information. Through the method, the Internet of Things terminal and the platform can utilize the DUC as a secret key to perform encryption and data interaction, and the DUC is not transmitted in the interaction process, so that the encryption reliability is improved, and the possibility of attack and data tampering is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet of Things, in particular to a communication method, platform, terminal and system of the Internet of Things. Background technique [0002] The monitoring system based on the Internet of Things has been applied in more and more fields, including camera monitoring, power equipment monitoring, gas pipeline monitoring, fire pipe network monitoring, environmental protection monitoring, etc., especially the remote monitoring system based on wireless Internet of Things technology has been obtained widely used. In these IoT monitoring systems, for the sake of safety, various monitoring terminals need to register and authenticate the monitoring business platform, monitor data transmission and other operations, and also accept control instructions. [0003] The lack of effective protection for data transmission security between IoT monitoring terminals, especially wireless terminals and IoT m...
