Embodiment 1

[0125] refer to figure 1 , which shows a flow chart of a communication method between IoT devices according to an embodiment of the present application, and the specific steps include:

[0126] Step 101, establishing a communication connection between a first IoT device and a trusted device.

[0127] Since the trusted device is trusted, in order to enable both the first IoT device and the second IoT device to obtain the first communication key in a safe and reliable manner, reduce the possibility of the first communication key leaking, and then realize encryption Communication, to improve the security of communication, can establish a communication connection between the first IoT device and the trusted device.

[0128] The first IoT device and the trusted device can form a local area network through the router.

[0129] The communication connection between the first IoT device and the trusted device can be established through TCP ((Transmission Control Protocol, Transmission ...

Embodiment 2

[0143] refer to figure 2 , which shows a flow chart of a communication method between IoT devices according to an embodiment of the present application, and the specific steps include:

[0144] Step 201, respectively establish communication connections between the trusted device and the first IoT device and the second IoT device.

[0145] Since the trusted device is trusted, in order to enable both the first IoT device and the second IoT device to obtain the first communication key in a safe and reliable manner, thereby realizing encrypted communication and improving the security of communication, they can be respectively A communication connection between the trusted device and the first IoT device and the second IoT device is established.

[0146] The trusted device can determine the first IoT device and the second IoT device from the Internet of Things, for example, by receiving user designation, random selection, receiving cloud designation, etc., to determine the first ...

Embodiment 3

[0155] refer to image 3 , which shows a flow chart of a communication method between IoT devices according to an embodiment of the present application, and the specific steps include:

[0156] In step 301, the trusted device respectively establishes communication connections between the trusted device and a first IoT device and a second IoT device.

[0157] Wherein, the way in which the trusted device respectively establishes the communication connection with the first IoT device and the second IoT device can refer to the relevant description in the foregoing, and details will not be repeated here.

[0158] In this embodiment of the present application, optionally, in order to make the first IoT device or the second IoT device determine that the trusted device is credible, that is, ensure the reliability of the trusted device, and improve the security of subsequent acquisition of the first communication key and reliability, improve the security and reliability of encrypted c...

Abstract

The embodiment of the invention provides a communication method and device between Internet of Things devices. The method comprises the following steps: establishing a communication connection betweena first Internet of Things device and a trusted device; obtaining a first communication key, wherein the first communication key is provided for the first Internet of Things device and / or the secondInternet of Things device through the trusted device; based on the first communication secret key, performing encrypted communication of the first Internet of Things device and the second Internet ofThings device, so that it is ensured that the first Internet of Things device and the second Internet of Things device can obtain the first communication key, encrypted communication is performed based on the first communication key, and the safety and reliability of communication between the first Internet of Things device and the second Internet of Things device are improved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a method and device for communication between devices of the Internet of Things. Background technique [0002] With the development of Internet of Things technology, the application of various Internet of Things devices is becoming more and more extensive. In order to realize the interconnection between the IoT devices, the IoT devices need to communicate with each other. [0003] In the prior art, IoT devices are directly connected and communicate in plain text, but plain text communication is likely to lead to data leakage, and the security of communication is low. Contents of the invention [0004] In view of the above problems, the present application is proposed to provide a communication method and device between IoT devices that overcome the above problems or at least partially solve the above problems. [0005] This application provides a ...
