AI Technical Summary

Technical Problem

In Wi-Fi networks, obtaining public key certificates by scanning device QR codes poses security risks and is inefficient, especially when multiple devices are connected and frequent operations lead to inefficiency.

Method used

By configuring the device to work in conjunction with the wireless network and certificate server, the public key certificate of the access device can be obtained online. This includes receiving and sending messages to obtain and verify the device address and service set identifier, ensuring that the device is within the pre-configured address list, and using the certificate server to manage the legitimacy of the public key certificate, thus achieving fully online operation.

Benefits of technology

It reduces security risks in the process of obtaining public key certificates, improves the efficiency of obtaining certificates, avoids the cost of pre-made certificates when devices are shipped, and supports rapid access to IoT terminals.

Abstract

The application provides a device public key certificate acquisition method and a communication device. In the method, a device receives a first message from a first access device, the first message being used for requesting a public key certificate of the first access device; a second message is sent to a wireless network, the second message being used for notifying the wireless network that a service set identifier serves the first access device; a third message is received from the first access device, the third message being used for indicating the public key certificate of the first access device; and the public key certificate of the first access device is acquired according to the third message. In this way, the public key certificate of the access device can be acquired online, which can reduce security risks and improve the acquisition efficiency of the public key certificate compared with the code scanning method.
