Mobile Internet virtual key authorizing system and hardware door lock control method thereof

Abstract

The invention relates to a mobile Internet virtual key authorizing system. The mobile Internet virtual key authorizing system comprises intelligent door locks with Bluetooth communication modules, a main smart phone with a Bluetooth communication module, a client smart phone with a Bluetooth communication module, and a server linked with all the smart phones through a wireless Internet. A control method comprises the following steps that firstly, each intelligent door lock with the Bluetooth communication module has a pair of RSA public and private secret keys; secondly, the server receives a secret key authorizing request of the main smart phone, generates an authorized secret key after verifying the ID of the main smart phone and sends the authorized secret key to the client smart phone; thirdly, the client smart phone and the intelligent door locks establish communication through Bluetooth; fourthly, the intelligent door locks obtain the secret key from the client smart phone through communication and then carry out comparison. By means of the system and the method, the effective time duration can be freely set, and thus the safety of virtual key remote authorization on the mobile Internet is greatly improved.

Description

technical field [0001] The invention relates to a mobile Internet virtual key authorization system and a hardware door lock control method thereof, belonging to the technical field of electronic intelligent door lock control. Background technique [0002] Traditional smart door locks generally use fingerprints, radio frequency IC cards, etc. as password input devices, and control the movement of the lock cylinder motor after the password verification of the internal circuit of the lock to achieve the purpose of opening the door. The disadvantage of this kind of door lock is that the duplication and delivery of the key requires face-to-face operations by both parties, which is very inconvenient for remote management of rental houses and house entrustment. The Bluetooth locks currently on the market are basically based on symmetric encryption technology, and most of them use AES encryption method to encrypt communication data. This encryption algorithm method is used in the co...

The disadvantage of this kind of door lock is that the duplication and transfer of the key requires face-to-face operations on both sides, which is very inconvenient for the remote management of rental houses and house entrustment leasing

At present, the Bluetooth locks on the market are basically based on symmetric encryption technology, and most of them use AES encryption method to encrypt communication data. This encryption algorithm method is used in the control of door locks, and the security cannot be guaranteed.
