Wireless communication method of wireless intelligent door lock

Abstract

The invention discloses a wireless communication method of a wireless intelligent door lock. According to the method, a key end processor is woken up by a low-frequency wake-up signal, a key ID is sent to a door lock base station by a high-frequency signal, the door lock base station performs decryption to obtain a local key, the encrypted door lock base station ID is sent to the key end by the high-frequency signal, the key end obtains the door lock base station ID after performing decryption and obtains a variable key according to the ID, the variable key is sent to the door lock base station through high frequency, and the lock base station compares the local key with the variable key, and then controls an actuator to open the door after confirming the match. By adopting the wireless communication method disclosed by the invention, the problem that the communication security of the wireless intelligent electronic door lock is not high is solved, the variable key can be formed by a rolling code and the local key, meanwhile since the rolling code is added to the encrypted data, the decrypted data and the variable key are both dynamically variable, each encrypted message encrypted by a double encryption algorithm has uniqueness, and the repetition probability of the encrypted message is infinitely close to zero, thereby effectively preventing a ciphertext from being recorded or cracked.

Description

technical field [0001] The present invention relates to an intelligent door lock, and more specifically, relates to a wireless communication method for a wireless intelligent electronic door lock. Background technique [0002] Smart home, as a popular industry in China today, has gradually entered a stable period, and door lock products that are also closely related to it, now mechanical door locks still occupy an absolute proportion. The intelligence of door locks is gradually attracting people's attention. In addition to the traditional opening methods, most of the smart door locks currently in use also add RFID magnetic cards, electronic passwords, fingerprint recognition, face recognition locks and radio frequency remote control switches. Wait for the smart opening method. [0003] Fingerprint passwords have the disadvantages of low fingerprint recognition rate performance, poor use flexibility and low security performance. For example, fingerprint password locks may no...

Problems solved by technology

[0003] Fingerprint passwords have the disadvantages of low fingerprint recognition rate performance, poor use flexibility and low security performance. For example, fingerprint password locks may not be recognized when fingers are oily and peeled. The probe is exposed, the safety performance is not high, and it is easy to be damaged by people, etc.

However, the magnetic card lock is not convenient to use, you must swipe the card every time you use it, and the security performance is poor, the magnetic card has no password interaction, no code hopping and encryption technology, and the password is single

The security performance of the electronic combination lock is poor, the password keyboard is exposed, it is easy to be destroyed and used, and the electronic password is also easy to be plagiarized. At the same time, the applicability of the electronic combination lock is poor, and it is not suitable for children and the elderly. The password must be changed after the password is unlocked.
