Equipment authentication method, Internet of Things terminal equipment, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an equipment authentication method, Internet of Things terminal equipment, electronic equipment and a storage medium, and relates to the field of network security, in particular to the field of equipment authentication. The method comprises the following steps: the Internet of Things terminal equipment performs multiplication operation with a preset target S box based on identification data of the Internet of Things terminal equipment to obtain encrypted data, and sends the encrypted data to gateway equipment; the gateway device receives the encrypted data and decrypts the encrypted data based on a preset target S box to obtain decrypted data; the gateway device compares the decrypted data with pre-stored identification data of the Internet of Things terminal device; and if the comparison is successful, allowing the Internet of Things terminal device to access the Internet through the gateway device. In this way, the problems that the cost is high and practical application cannot be met in the implementation scheme of secure access of the terminal equipment can be solved, effective calculation can be independently completed without depending on external knowledge under the condition that the resources of the terminal equipment are limited, and the investment of hardware facilities such as a gateway can be reduced.

Description

technical field [0001] The present disclosure relates to the field of network security, and in particular, to the field of device authentication. Background technique [0002] Terminal devices in the Internet of Things need to access the Internet, and carry out information transmission and interaction based on Internet protocols. In order to ensure the security of terminal devices when accessing the Internet of Things, the most common technical solution for secure access of IoT terminal devices is to set up an access gateway at the Internet entrance, and the gateway will read the access gateway when the IoT terminal device is connected. Identity information, and then verify the validity of the identity of the IoT terminal device through an algorithm. [0003] The design process of the solution mainly based on hardware such as gateways is complicated, and the installation cost is high; if it is moved to the terminal device side for verification, it will be limited by the low...

Problems solved by technology

[0003] The design process of the scheme based on gateway and other hardware methods is complicated, and the laying cost is high; if it is moved to the terminal device side for verification, it will be limited by the low computing power of the terminal device and limited resources such as memory, resulting in a decrease in verification efficiency. Meet the practical application
