Problems solved by technology

However, at present, the encryption key between the smart home device and the server is fixed. After the key is cracked, it is easy to cause the leakage of the transmitted data, which in turn leads to the loss of control of the Internet of Things system, and the security risk is very large.

Embodiment Construction

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0073] Such as figure 1 As shown, the present application provides an Internet of Things system, and the system includes a smart home device 100 and a server 200 . The smart home device 100 can perform data transmission with the server 200 .

[0074] Before data transmission between the smart home device 100 and the server 200 , the smart home device 100 needs to log in to the server 200 , and the process of logging in to the server 200 by the smart home device 100 is first introdu...

Abstract

The invention provides a data transmission method and an IoT system. The method comprises that in the process that intelligent household equipment makes UDP communication with a server via a first secrete key, a secret key changing instruction is sent to the intelligent household equipment in a UDP communication manner; a first feedback message sent by the intelligent household equipment in the UDP communication manner is received; under the condition that the intelligent household equipment establishes TCP communication connection with the server, a secret key changing request sent by the intelligent household equipment in the TCP communication manner is received; a second secret key which is generated randomly is sent to the intelligent household equipment in the TCP communication manner; and after that the intelligent household equipment receives the second secret key successfully, a second feedback message sent by the intelligent household equipment is received in the TCP communication manner. The secret key in the invention is changeable but not fixed, the changed secret key is transmitted in the TCP communication manner, and thus, the safety of data to be transmitted between the intelligent household equipment and the server is ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method and an Internet of Things system. Background technique [0002] With the continuous development of science and technology, smart home devices have gradually become popular. In order to remotely control smart home devices, WIFI modules are generally installed in smart home devices, so that smart home devices can communicate with servers wirelessly. Smart home devices and servers form the emerging Internet of Things system. [0003] Currently, in the Internet of Things system, UDP (User Datagram Protocol, User Datagram Protocol) is used for communication between smart home devices and servers. UDP is a connectionless transport layer protocol in the OSI (OpenSystem Interconnection, Open System Interconnection) reference model, which provides transaction-oriented simple and unreliable information transmission services. [0004] In orde...
