it should be noted that, the mobile terminal may be installed with a matching application APP, and the user may control the household appliance through the application APP. For example, in the present embodiment, a user may input a control instruction through the application APP.
It should be added that after receiving the random number, the mobile terminal may directly obtain the control instruction, and report the obtained control instruction and the random number to the server at the same time, and the server generates the authentication key according to the random number and the second key, and then encrypts the control instruction by using the second key.
S4: and receiving the encrypted control instruction sent by the server, and sending the encrypted control instruction to the communication module, wherein the communication module decrypts the encrypted control instruction through the authentication key so as to enable the household appliance to execute the control instruction.
That is, in controlling the home appliance, a control instruction may be transmitted to the server, wherein the server may acquire address information such as a MAC address and encrypt and verify the control instruction and a user identification code such as a user ID with an authentication key. After receiving address information sent by a server and a control instruction and a user identification code which are encrypted by an authentication key, sending the control instruction and the user identification code which are encrypted by the authentication key to a communication module, wherein the communication module decrypts the encrypted control instruction and the user identification code through the authentication key to obtain the control instruction and the user identification code, compares the user identification code which is received by verification with the user identification code which is written in the communication module, and executes the control instruction if the user identification code and the user identification code are consistent.
Therefore, the control command is encrypted, the safety of the command is ensured, and the command is prevented from being tampered.
Further, as shown in fig. 2, according to an embodiment of the present invention, the method for controlling a home appliance further includes:
s5: receiving an execution success instruction sent by the communication module, wherein the communication module sends the execution success instruction after the household appliance executes the control instruction;
s6: sending a state query instruction to a communication module, wherein the communication module feeds back the state information of the household appliance after receiving the state query instruction;
s7: and receiving the state information fed back by the communication module and reporting the state information to the server.
That is, after the household appliance executes the control command, the successful execution command sent by the communication module can be received, the state query command can be sent to the communication module, and after the state information replied by the communication module is received, the state information is reported to the server.
Specifically, after the household appliance executes the control instruction, the state of the household appliance changes, and then the server can monitor the state of the household appliance in real time by receiving the state information replied by the communication module and reporting the state information to the server.
As described above, the specific process of the control method of the household appliance according to the embodiment of the present invention when controlling the household appliance is as follows:
and connecting a communication module (reconnection after disconnection), wherein the communication module generates a random number at each connection, and the communication module also generates an authentication key according to the random number and a second key PSK 2.
And reporting the random number to a server after receiving the random number sent by the communication module, wherein the server generates an authentication key according to the random number and a second key PSK 2.
And sending a control instruction to a server, wherein the server encrypts the control instruction and the user identification code by an authentication key, and after receiving the control instruction and the user identification code encrypted by the authentication key, sends the encrypted control instruction and the encrypted user identification code to a communication module, wherein the communication module verifies the encrypted control instruction and the encrypted user identification code and executes the control instruction after the control instruction and the encrypted user identification code are successfully verified.
After receiving a successful execution instruction sent by the communication module, sending a state query instruction to the communication module, and after receiving state information replied by the communication module, reporting the state information to the server.
Further, according to an embodiment of the present invention, as shown in fig. 3, the method for controlling a home appliance further includes:
s8: receiving the encrypted state information sent by the communication module, wherein the communication module encrypts the state information of the household appliance through the authentication key;
s9: and reporting the encrypted state information to a server.
That is to say, when the home appliance reports the status, after the home appliance is successfully bound with the home appliance, the communication module can acquire the status information of the home appliance at preset time intervals, encrypt the status information of the home appliance through the authentication key, receive the encrypted status information sent by the communication module, and report the encrypted status information to the server.
Therefore, the state information is encrypted, the safety of the command is ensured, and the command is prevented from being tampered.
As described above, the control method of the home appliance according to the embodiment of the present invention specifically processes the status reporting as follows:
and connecting a communication module (reconnection after disconnection), wherein the communication module generates a random number at each connection, and the communication module also generates an authentication key according to the random number and a second key PSK 2.
And reporting the random number to a server after receiving the random number sent by the communication module, wherein the server generates an authentication key according to the random number and a second key PSK 2.
After receiving the state information of the household appliance which is sent by the communication module and encrypted by the authentication key, reporting the state information encrypted by the authentication key to the server, wherein the server can decrypt and store the encrypted state information.
Further, according to an embodiment of the present invention, as shown in fig. 4, when the mobile terminal is bound to the communication module, the method further includes:
s11: and receiving the encrypted first identification information sent by the communication module, wherein the communication module encrypts the prestored first identification information through a first secret key.
It should be noted that, the mobile terminal may be installed with a matching application APP, and the user may control the household appliance through the application APP. For example, in the present embodiment, the user may control the mobile terminal to be bound with the communication module, i.e. with the household appliance, through the application APP.
The mobile terminal and the communication module can be bound according to the binding instruction.
It should be further noted that the first identification information is pre-stored in the communication module or the storage unit of the household appliance, and the first identification information may include an identification code of the household appliance, for example, an SN code of the household appliance.
Specifically, after communication is established with the communication module, at the time of initial binding, the encrypted first identification information is received by communicating with the communication module, wherein the communication module can encrypt the pre-stored first identification information by the first key. In other words, the first identification information encrypted by the first key may be read to the pass module. Wherein the first key may be pre-stored in the communication module.
S12: and acquiring second identification information of the household appliance, and sending the encrypted first identification information and the second identification information to the server, wherein the server acquires the binding information after judging that the first identification information is consistent with the second identification information, and encrypts the binding information through the first key.
Note that the communication module and the server initialize a unified first key PSK1 by default. In other words, the communication module and the server have a pre-stored unified first key PSK 1.
Wherein the binding information may include the user identification code and the second key. It should be noted that the user identification code and the second key may be encrypted separately, or the user identification code and the second key may be encrypted together.
Specifically, a two-dimensional code can be pasted on the body of the household appliance, second identification information is arranged in the two-dimensional code, and the second identification information can be obtained by scanning the two-dimensional code. The second identification information may include an identification code of the home appliance, for example, an SN code of the home appliance.
It should be noted that the second identification information may be encrypted or not. When the second identification information is encrypted, the second identification information may be encrypted with the same first key as the first identification information. At this time, the server can judge whether the first identification information is consistent with the second identification information by directly comparing whether the encrypted first identification information is consistent with the encrypted second identification information, and because the same key is used for encryption, when the encrypted first identification information is consistent with the encrypted second identification information, the first identification information is consistent with the second identification information. Or, the server may decrypt the encrypted first identification information and the encrypted second identification information, and then directly compare the first identification information with the second identification information to determine whether the first identification information is consistent with the second identification information.
