After the home appliance is connected to the Internet of Things, it is legally connected to the Internet of Things through the verification of the signature information, which solves the problem that the home appliances are illegally connected to the Internet of Things, causing hidden dangers to the security of the Internet of Things information. In one embodiment Because the signature information is stored in the secure storage area of the home appliance device where the communication module is located, the information in the secure storage area cannot be read by the external device, so that the signature information cannot be obtained by the external device, that is, other devices cannot be obtained from the home appliance. Obtaining signature information in the device to illegally obtain information in the Internet of Things, further ensuring the security of the Internet of Things information.

Based on the anti-counterfeit generation device of the above-mentioned home appliance, an anti-counterfeit preparation method for the home appliance of the present application is proposed.

Referring to FIG. 2, FIG. 2 is an embodiment of an anti-counterfeiting preparation method for a home appliance device of the present application. The anti-counterfeiting preparation method for a home appliance device includes the following steps:

Step S10: Obtain a MAC address of the communication module to generate an anti-counterfeit file according to the MAC address.

In the present application, the anti-counterfeit generation device of a home appliance can be used to generate anti-counterfeit information of the home appliance. Specifically, the anti-counterfeit generation device of the home appliance obtains the MAC address of the communication module, and then generates an anti-counterfeit file according to the MAC address. The anti-counterfeit file is a license code file, that is, a license file.

Step S20: Generate a private key and a public key corresponding to the anti-counterfeit file;

When the device is legally connected to the Internet of Things, the verification information uploaded by the home appliance is decrypted according to the MAC address and the public key to determine whether the home appliance is a legal access device.

In step S30, the serial number of the communication module is signed according to the private key to obtain signature information, and the signature information is stored in a secure storage area of the home appliance device where the communication module is located.

After generating the private key of the license file, the anti-counterfeit generating device of the home appliance stores the private key of the license file and the MAC of the communication module, and then burns the license file and the MAC address to the communication module.

After the communication module is programmed, it can be installed on home appliances. At this time, the anti-counterfeit generation device of the home appliance will be connected to the home appliance where the communication module is located; then, the MAC address of the communication module of the home appliance is read to determine the corresponding private key based on the MAC address; The serial number is signed to obtain signature information. After generating the signature information, the home appliance will place the signature information in a secure storage area. The information stored in the secure storage area cannot be read by external devices, so that other devices cannot obtain signature information from home appliances to illegally obtain information in the Internet of Things, ensuring the security of the Internet of Things information.

The anti-counterfeit preparation process for the home appliance by the anti-counterfeit generation device of the home appliance involves the generation and programming of the MAC address and license of the communication module, the generation of the private and public keys of the license, and the generation of signature information of the home appliance. In some embodiments, in addition to the anti-counterfeiting preparation of the home appliance, the anti-counterfeiting generating device of the home appliance is also used for the production of the communication module. The specific process is as follows:

1. Put the communication module into the production fixture of the anti-counterfeit generation device of home appliances. At this time, the communication module does not program and firmware information.

2. The production software of the anti-counterfeit generation device of home appliances corrects the radio frequency of the communication module;

3. Obtain a MAC address for the communication module of the home appliance and configure the applied MAC address in the communication module. The MAC address can be divided into multiple MAC address segments according to the number of communication modules produced in the same batch, and for each communication module Allocate a MAC address segment, which is the MAC address of the communication module;

4. The anti-counterfeit generating device of the home appliance generates a license file of the communication module according to the MAC address;

5. The key generation device of the anti-counterfeit generation device of the home appliance generates a public key and a private key corresponding to the license file. The key generation device can be a component of the anti-counterfeit generation device of the home appliance, and can also communicate with the home appliance through a USB interface, etc. The anti-counterfeit generation device is connected. The anti-counterfeit generation device of the home appliance stores the private key and the MAC address in association, and uploads the public key and the MAC address to the IoT server;

6. The anti-counterfeit generation device of the home appliance programs the communication module to determine the patch firmware, that is, the pacth firmware, the application firmware and other information that needs to be programmed;

7. The anti-counterfeit generating device of household appliances configures the serial number of the communication module, and writes the serial number, pacth firmware, application firmware, MAC address, license file and other information to the communication module;
