Optionally, Fig. 6 is that a kind of details that step S110 in the information ciphering method for implementing to exemplify is corresponded to according to Fig. 5 is retouched
State, as shown in fig. 6, the step S110 in the information ciphering method can also comprise the following steps.
In step S111, terminal receives the timestamp that gateway is sent according to default time interval.
The time interval of gateway sending time stamp is a pre-set time range value, which cannot be set
It is excessive, it can not set too small, in actual intelligent domestic system, the time interval can be finely adjusted in advance.Show one
In example property embodiment, time interval is preset as 5 seconds.
For terminal when receiving the timestamp that gateway is sent at predetermined intervals, it does not immediately obtain the time
Stamp, and only when generating control information according to the control operation of triggering, just obtains timestamp that it receives and is added into
In control information.
In step S112, the timestamp received when generating control information is obtained in the timestamp sent from gateway.
Using method as above, gateway is stabbed according to default time interval to terminal sending time, so that terminal is generating
During control information, the last timestamp received is directly searched in the timestamp for receiving gateway transmission, so that nothing
It need to be stabbed to the special query time of gateway, substantially increase the convenience for obtaining timestamp.
Optionally, Fig. 7 is that the another kind details that step S110 in the information ciphering method for implementing to exemplify is corresponded to according to Fig. 5 is retouched

As previously described, timestamp is the time mark carried out in a time metric.
To ensure the accuracy of timestamp, make gateway after receive information can according to timestamp sentencing into the row information true and false
Disconnected, gateway will be appreciated that the timestamp that terminal adds in the control information.Therefore, when terminal will send control information to gateway,
Request is obtained by being stabbed to gateway sending time, request gateway sending time stamp, so as to ensure that the timestamp is that gateway is known
Timestamp.
In LAN, terminal is stabbed to gateway sending time by router and obtains request.
In step sl 15, the timestamp for receiving gateway respond request and returning.
Gateway is stabbed to terminal sending time immediately when the timestamp that receiving terminal is sent obtains request.
Using method as described above, terminal stabs to gateway sending time when generating control information and obtains request, request
Gateway sending time is stabbed, and travel frequently over router without gateway stabs to terminal sending time, so as to avoid the waste of resource.
Fig. 8 is another information ciphering method flow chart according to an exemplary embodiment, as shown in figure 8, the letter
Encryption for information method may comprise steps of.
In step S210, the encryption information of gateway receiving terminal transmission.
The encryption information that gateway receiving terminal is sent is the encryption information that terminal is sent by LAN to gateway.
In step S220, it is decrypted according to default key pair encryption information, obtains control information.
As previously described, the key each preserved in gateway and terminal is identical or corresponding.
One information of terminal-pair is encrypted according to its key stored be sent to gateway after, gateway is deposited according to it after the receipt
The key of storage can successfully be decrypted.
For example, the key stored in terminal is key X1, the key stored in gateway is key X2, key X2 and key X2
Be it is identical or corresponding, can be right by key X2 when being encrypted to obtain encryption information Y2 to information Y1 by key X1
Encryption information Y2 successful decryptions obtain information Y1.
In step S230, the timestamp in control information is obtained, timestamp and control when judging receiving encryption key
Whether the time interval between timestamp in information is less than default time threshold, if yes (Y), then performs step S241；
If NO (N), then perform step S242.
As previously described, terminal is that the control information for adding timestamp is encrypted.
Thus, it is also to include timestamp after encryption information is decrypted, in obtained control information.
As previously described, timestamp is that the time carried out in time metric is marked.Thus, in the timestamp of different time
It is different, the temporal information of timestamp description is to change with the passing of time.
For example, the time that timestamp is the system time progress to gateway marks, terminal is in the control operation according to triggering
When generating control information, the system time 12 that the time stamp T 1 that gateway is sent is gateway is obtained:00:00, and receiving encryption key
When gateway when being receiving encryption key of time stamp T 2 system time 12:00:03.
In another example timestamp is that the time that the timer in gateway carries out is marked, terminal is grasped according to the control of triggering
When making generation control information, the timing 30 that the time stamp T 1 that gateway is sent is gateway Timer is obtained:00:10, and receive and add
The timing 30 of gateway Timer when time stamp T 2 during confidential information is receiving encryption key:00:13.
Time threshold is a pre-set time range value, which cannot set excessive, can not set
It is too small, by the data transfer in actual LAN, time threshold can be finely adjusted.In one exemplary embodiment, the time
Threshold preset is 5 seconds.
If the time interval between the timestamp in timestamp and control information during receiving encryption key is less than default
Time threshold, then it is effective to show the control information, is not that other-end is attacked by pretending to be in LAN.Cause
This, is controlled relevant device according to the control information.Because if control information is effective, terminal-pair control information into
Row encryption is almost instantaneity with gateway receiving encryption key, i.e. terminal-pair control information is encrypted to receive with gateway and encrypts
Time interval between information is typically very little.
If the time interval between the timestamp in timestamp and control information during receiving encryption key is not less than default
Time threshold, then show when terminal-pair control information is encrypted and during encryption information that gateway receiving terminal is sent between
Time interval is larger, it is likely to and the other-end in LAN is attacked by pretending to be, and therefore, abandons the control information,
Corresponding operating is not performed according to the control information.
In step S241, control information is sent to relevant home equipment, so that home equipment is according to control information
Work.
In step S242, control information is abandoned.
Using method as described above, gateway is in the timestamp during control information is obtained after being decrypted to encryption information, only
There is the time interval between the timestamp in the timestamp and control information in receiving encryption key to be less than default time threshold
Value, is just sent to relevant home equipment by the control information, is that the home equipment performs corresponding operating, avoids other-end from leading to
Cross to pretend to be and gateway is attacked, so as to ensure that the communication security in intelligent domestic system, substantially increase to related household
The security that equipment is controlled.
Fig. 9 is the side being controlled in a kind of intelligent domestic system according to an exemplary embodiment to home equipment
Method schematic diagram.
In step S310, terminal, gateway are connected by the communication with cloud server, receive cloud server hair respectively
The key information sent, key information include default key.
It is understood that terminal and gateway are encrypted into row information or key when information is decrypted is side with key information
Formula is stored in advance in its respective storage, and then the key in key information of the terminal by obtaining its storage, and according to this
Control information is encrypted in key, and gateway is after encryption information is received, in the key information by obtaining its storage
Key, and be decrypted according to the key pair encryption information.
And when terminal, gateway communicate with cloud server connect first, cloud server believes the key comprising key
Breath is sent respectively to terminal and gateway, and the key information that terminal receives respectively with gateway is identical, so as to ensure that terminal exists
After being sent to gateway to control information encryption, gateway can be smoothed out decrypting.
In step s 320, terminal adds net when generating control information according to the control operation of triggering in control information
Close the timestamp sent.
In step S330, terminal is encrypted the control information for adding timestamp according to default key, and will
To encryption information be sent to gateway.
In step S340, the encryption information of gateway receiving terminal transmission, believes encryption according to the encryption and decryption mode of agreement
Breath is decrypted, and obtains control information.
In step S350, gateway obtains the timestamp in control information, timestamp when judging receiving encryption key with
Whether the time interval between timestamp in control information is less than default time threshold, if it has, then performing step S361；
If it has not, then perform step S362.
