The application of the intelligent household appliance can adjust the current communication safety level according to whether the intelligent household appliance is invaded or not, the intelligent household appliance is prevented from being controlled at will, the use data of the intelligent household appliance is prevented from being leaked, and the safety is improved.
Different communication security levels correspond to different communication encryption methods, the higher the communication security level is, the more complicated the corresponding communication encryption method is, the better the confidentiality is, and correspondingly, the longer the time required for encrypting and decrypting data is.
The first initial communication security level is generally the lowest communication security level, and data transmission only needs simple encryption or does not need encryption. The first target level is higher than the first initial communication security level, and therefore, data needs to be decrypted, which takes a long time.
In the step S1, whether the current intelligent household appliance is invaded or not can be judged by acquiring the control frequency of the current intelligent household appliance, wherein the acquisition mode of the control frequency is the prior art; or a behavior library is preset, and whether the current behavior is an intrusion behavior is judged according to the behavior library, and the establishment mode of the behavior library is also the prior art.
In some embodiments, step S2 comprises:
A1. acquiring the position information of the current intelligent household electrical appliance;
A2. and acquiring a first target grade corresponding to the current intelligent household appliance from a preset first grade form according to the position information.
In the step A1, the position information of the intelligent household appliance may be obtained through a preset classification table, such as a bedroom door and a bedroom; television, living room; certainly, the position information of some intelligent household appliances is not fixed, for example, a sweeping robot, a house model is established through the existing three-dimensional modeling, and then the real-time position information is acquired through a built-in WiFi module. The first level form records first target levels corresponding to different position ranges, and the first target levels can be preset according to actual needs.
In step A2, the first target level is higher than the first initial communication security level.
By the method, the proper communication security level can be adjusted according to the position of the intelligent household appliance, the position is important, the communication security level of the intelligent household appliance which needs to frequently relate to the privacy data of the user is improved, and the privacy data is prevented from being leaked; the ordinary intelligent household electrical appliance which is generally located and does not need to frequently relate to user privacy data keeps the original communication security level or properly increases the communication security level, the influence of overlong data transmission decryption time caused by overhigh communication security level is reduced, the ordinary intelligent household electrical appliance can be normally used as far as possible, the classified encryption of the intelligent household electrical appliance is realized, and the applicability is improved.

In the step D2, the first target levels corresponding to different control instructions are recorded in the fourth level form, and may be preset according to actual needs. Assuming that, in the fourth level table, the communication security level corresponding to the control command for turning on the display lamp is level 2, and the communication security level corresponding to the control command for turning up the temperature and turning down the temperature is level 5, when the air conditioner is invaded, the communication security level corresponding to the control command for turning on the display lamp is adjusted from the first initial communication security level to level 2, and the communication security level corresponding to the control command for turning up the temperature and turning down the temperature is adjusted from the first initial communication security level to level 5.
Through the mode, when the intelligent household appliance is invaded, the communication safety level of the important control instruction can be increased, and an invader is prevented from randomly controlling the important instruction.
In a further embodiment, step S3 is followed by:
s4, performing self-checking on the current intelligent household appliance every other second preset time period to judge whether the current intelligent household appliance is still invaded;
s5, if the current intelligent household appliance is not invaded, the communication security level of the current intelligent household appliance is adjusted downwards according to the first preset level, and the step S4 is repeatedly executed until the communication security level of the current intelligent household appliance is restored to the first initial communication security level;
and S6, if the current intelligent household electrical appliance is still invaded, maintaining the communication security level of the current intelligent household electrical appliance unchanged, and repeatedly executing the step S4.
In step S4, the second preset time period may be set as needed.

And if the current intelligent household appliance is still invaded, maintaining the communication security level of the current intelligent household appliance unchanged, and performing self-checking after a second preset time period.
Through this kind of mode, compare once only with communication security level drop to first initial communication security level, adopt the mode that reduces step by step safer, further reduce the risk.
In some preferred embodiments, step S3 is followed by:
taking the current intelligent household appliance as a center, acquiring a communication security level required by other intelligent household appliances in the intelligent household appliance group within a first preset range when the other intelligent household appliances suffer from invasion, and recording the communication security level as a second target level;
and sending a grade adjusting instruction to other intelligent household appliances which are lower than the corresponding second target grade and are in the first preset range, so that the corresponding intelligent household appliances can adjust the communication safety grade of the intelligent household appliances.
The first preset range can be set as required, for example, a circular area formed by using the intelligent household appliance as a center.
