in the embodiment of the application, in order to improve the communication security between the client and the smart home devices, a corresponding communication key is set for each smart home device, and the communication keys of different smart home devices may be different. And then, a communication key list is locally stored in the client, wherein the communication key list comprises a plurality of communication keys of intelligent household equipment belonging to the same intelligent household system as the client and a mapping relation between the communication keys and the intelligent household equipment. When the client communicates with the intelligent household equipment, the instruction data are encrypted based on the communication key which has the mapping relation with the intelligent household equipment in the communication key list, so that the communication safety is improved.
However, if the communication key corresponding to the smart home device is generated only once and cannot be changed, the communication key is easily decoded by an illegal operator, so in order to further improve the security of communication, in the smart home control method provided in the embodiment of the present application, the communication key of each smart home device is set to be updatable. Specifically, in the operation process of the client, whether a communication key update condition is met can be detected, and the communication key of the smart home device is updated under the condition that the communication key update condition is determined to be met.
As an embodiment, during the operation process of the client, the current time may be collected in real time, and whether the current time is the key update time is detected, and if it is determined that the current time is the key update time, it is determined that the communication key update condition is satisfied.
As an alternative implementation manner, the key update time may be one or more time values set according to actual requirements, for example, the key update time may be 14:00 per day, and for example, the key update time may be 10:00, 12:00, and 00:00 per day. Based on this, when detecting whether the current time is the key update time, the current time may be compared with each set key update time, and if the current time is consistent with any one of the key update times, the current time is determined to be the preset key update time. By the method, the user-defined communication key updating time can be realized.
As another optional implementation manner, the communication key of the smart home device may also be set to be updated periodically, for example, once every 2 hours. Based on this, when detecting whether the current time is the key update time, the latest storage time corresponding to the locally stored communication key list may be obtained, a time difference between the current time and the latest storage time is calculated, and if it is determined that the time difference is equal to a preset time value (for example, 2 hours), the current time is determined to be the preset key update time. For example, the communication key of the smart home device is set to be updated every 2 hours, and if the last update time is 10:00 and the current time is 12:00, the current time is determined to be the key update time. In this way, periodic updates of the communication key can be achieved.
