The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present application, belong to the protection scope of the present application.

In practical application, the specified cloud server can generate accurate license information, but the cloud server does not send the license information immediately, but can reach an agreement with the intelligent household appliance, and appropriate time delay is carried out according to actual conditions, so that the license information is sent at an appropriate time. Therefore, even if the license generation program is leaked, other pseudo base stations can generate accurate license information according to the license generation program, but the intelligent household appliance can not burn the license information until the intelligent household appliance is legal when the license information is sent to the intelligent household appliance.

According to the method and the device, the intelligent household appliances are used for matching and verifying the sending time information of the request information and the arrival time information of the license information, so that whether the license information is sent by the appointed cloud server or not is judged, misuse caused by the agency factory due to secret leakage of the license generating program is prevented, property loss is reduced, and safety is improved.

In step B2, a plurality of first thresholds may be preset to correspond to different interface flows, a plurality of second thresholds are preset to correspond to different first thresholds, when the real-time interface flow reaches a certain first threshold, the second threshold may be obtained according to the first threshold, and the first preset time interval is extended or reduced by the second threshold.
By the method, the first preset time interval can be adjusted in real time according to the interface flow information of the router, and adaptability and verification accuracy are improved.

By the method, the first preset time interval can be adjusted in real time according to the network downloading speed, and adaptability and verification accuracy are improved.
In some preferred embodiments, the current network quality information includes a network response speed, and step A1 includes:

E2. calculating a network response speed according to the plurality of first communication time lengths;
the step A2 comprises the following steps:
E3. and adjusting the first preset time interval according to the network response speed.
In step E1, the probe packet may be generated by an existing generator.
In step E2, the network response speed is equal to the sum of all the first communication durations divided by the number of probe packets.
In step E3, a plurality of network response speed intervals and a plurality of third preset time intervals may be preset, and each network response speed interval corresponds to one third preset time interval, so that when the network response speed is in a certain network response speed interval, a corresponding third preset time interval may be obtained according to the network response speed interval, and the third preset time interval is used to replace the first preset time interval.

In other embodiments, step A1 comprises:
F1. acquiring current date information;
the step A2 comprises the following steps:

In step F1, the manner of acquiring the current date information is the prior art.
The current date information includes year, month and day, and step F2 includes:
acquiring the year;
acquiring a first preset delay time according to the year;
and adjusting the first preset time interval according to the first preset delay time.
For example, the acquired year is 2020, the corresponding first preset delay time is 200 ms, and 200 ms is added to the original first preset time interval as a new first preset time interval (that is, the start time of the new first preset time interval is 200 ms later than the start time of the original first preset time interval, and the end time of the new first preset time interval is 200 ms later than the end time of the original first preset time interval).
In other embodiments, step F2 comprises:
acquiring a month;
acquiring a second preset delay time according to the month;
and adjusting the first preset time interval according to the second preset delay time.
For example, the acquired month is 10 months, the corresponding second preset delay time is 100 milliseconds, and 100 milliseconds are added to the original first preset time interval as a new first preset time interval (that is, the starting time of the new first preset time interval is 100 milliseconds later than the starting time of the original first preset time interval, and the ending time of the new first preset time interval is 100 milliseconds later than the ending time of the original first preset time interval).
In other embodiments, step F2 comprises:
acquiring the number of days;
acquiring a third preset delay time according to the number of days;
and adjusting the first preset time interval according to the third preset delay time.
For example, the number of days of the acquisition is 20, the corresponding third preset delay time is 50 milliseconds, and 50 milliseconds are added to the original first preset time interval as a new first preset time interval (that is, the start time of the new first preset time interval is 50 milliseconds later than the start time of the original first preset time interval, and the end time of the new first preset time interval is 50 milliseconds later than the end time of the original first preset time interval).
In practical application, the entrusting party may set different delay times for products on different dates, so as to conveniently distinguish product batches. The delay time is calculated automatically according to the current date information by the intelligent household appliance so as to adjust a first preset time interval (the burning program of the intelligent household appliance is provided by a client and is invisible after being packaged, and a foundry cannot know the content of the calculation program), and meanwhile, the delay program is arranged on the cloud server so that the second sending time of the license information can be adjusted according to the date, products with different production dates can be distinguished conveniently, meanwhile, the randomness of a verification mode is increased, and the products are more difficult to crack.
