Embodiment 1

[0118] User A's home appliance is a smart rice cooker of a certain brand I, and it can be known that the smart rice cooker has two encryption commands in the Bluetooth broadcast data A sent during the Bluetooth network distribution process. For example, the two encryption commands are encryption commands 5 and an encryption instruction 10, and the encryption rule of the encryption instruction 5 is the AES encryption algorithm, and the encryption rule of the encryption instruction 10 is the DES encryption algorithm; the smart rice cooker sends the Bluetooth broadcast data A according to the rules in Table 1.

[0119] The hacker has a fraudulent device K, and it can be seen that the Bluetooth broadcast data sent by the fraudulent device K itself is not equal to the Bluetooth broadcast data A of the smart rice cooker, because the hacker can perform the Bluetooth broadcast data of the fraudulent device K according to the Bluetooth broadcast data A. Tampering, the tampered Bluetooth...

Embodiment 2

[0128] User A's home appliance is a smart rice cooker of a certain brand I, and there are two encrypted instructions in the Bluetooth broadcast data A sent, for example, the two encrypted instructions are encrypted instruction 5 and encrypted instruction 10, and the encrypted instruction 5 is encrypted. The rule is the AES encryption algorithm, and the encryption rule of the encryption sequence 10 is the DES encryption algorithm; the smart rice cooker sends the Bluetooth broadcast data A according to the rules in Table 1; a hacker has a malicious terminal that can be connected to the home appliance, then the hacker uses the malicious terminal Follow the steps below:

[0129] (1) The user's smart rice cooker sends Bluetooth broadcast data A, the malicious terminal receives the Bluetooth broadcast data A, and connects to the Bluetooth of the smart rice cooker, but the malicious terminal does not know the specific encryption rules of the encryption sequence 5, therefore, the malic...

Abstract

The embodiment of the invention relates to the technical field of smart home, in particular to a household appliance, an application terminal and a Bluetooth network distribution method and system, and is used for solving the problem of low safety caused by Bluetooth network distribution in the household appliance. The household appliance comprises: a Bluetooth module used for sending Bluetooth broadcast data, the Bluetooth broadcast data comprising a first encryption instruction, and the first encryption instruction being used for instructing to encrypt the Bluetooth broadcast data according to a first encryption rule, and receiving first encrypted broadcast data sent by an application terminal; and the MCU is used for encrypting the Bluetooth broadcast data by using the first encryption rule to obtain second encrypted broadcast data, and disconnecting the Bluetooth connection with the application terminal after determining that the first encrypted broadcast data and the second encrypted broadcast data are inconsistent.

Description

technical field [0001] The embodiments of the present invention relate to the field of smart home technology, and in particular to a home appliance, an application terminal, and a Bluetooth network distribution method and system. Background technique [0002] With the development of Internet technology, smart home devices have become popular, and more and more families have smart home devices that can be connected to routers. When smart home devices need to be connected to routers, they need to obtain the SSID (ServiceSet Identifier, Service Set Identifier) ​​of the router. ID) and password (PASSWORD) to achieve network distribution. Among the network distribution methods of smart home devices, a commonly used method for network distribution of home appliances is Bluetooth network distribution. [0003] However, in the current Bluetooth distribution network mode of home appliances, due to the visibility of Bluetooth broadcasts, some lawbreakers have caused security damage. ...
