Therefore, the deciphering by deciphering module 26 obtains raw data, thereby obtains corresponding product ID, frame hopping and corresponding the driving unblanked or the key information of locking.
If be in learning state, then the remote control gate lock 20 of receiving end receives after the complete data of a frame, judges at first whether check code is correct, if correct, then according to top described, utilizes 26 pairs of data of deciphering module to be decrypted.Otherwise, then think misdata, do not process.Then judge by control module 22 whether sequence number is legal, if sequence number also is legal, the data after then will deciphering deposit in the second memory module 24.
In addition, the present invention also provides opening/blocking method of a kind of remote control gate lock, and the method step as shown in Figure 2.
At first, triggering the button of remote-control key presses, open/block signal (step 102) to send to corresponding remote control gate lock, after receiving trigger pip, read product ID, frame hopping and the random number of preserving in the remote-control key memory block, and then upgrade corresponding frame hopping and random number (step 104).
Then, the random number that utilization is read generates the cipher mode code, with to the product ID that reads and frame hopping and trigger the encryption of sorting of raw data that key information corresponding to remote-control key form, and utilize encryption key that the rear enciphered data that obtains of ordering encryption is fixed code encryption, the data after then will encrypting are carried out high-frequency emission (step 106) to remote control gate lock.
Remote control gate lock is corresponding to be received enciphered data and carries out corresponding fixed code deciphering and ordering deciphering, to obtain corresponding raw data (step 108).
Read product ID, frame hopping and the key information preserved in the memory block in the remote control gate lock after the decoding, and corresponding product ID, the frame hopping of the raw data that obtains with deciphering mate, to judge whether to carry out opening/block action (step 110) of remote control gate lock.And, by judging the key information in the raw data, can judge that execution is unblanked accordingly or block action.
In certain embodiments, fixed code encryption or the encryption of sorting can be only carried out in the step 106, certainly by this double-encryption mode of encryption and the fixed code encryption of sorting, the safer sending and receiving of data can be realized.
