Intelligent door lock control method and device

Abstract

The invention provides an intelligent door lock control method and device. The intelligent door lock control method comprises steps as follows: communication connection between a door lock main unit and an intelligent key is established; the door lock main unit generates a registration secret key and sends the registration secret key to the intelligent key; the door lock main unit generates a data secret key according to the registration secret key, and authentication certification between the door lock main unit and the intelligent key is completed; the door lock main unit encrypts an unlocking code with the data secret key, and the encrypted unlocking code is sent to the intelligent key; the door lock main unit responds to an unlocking code received by the door lock main unit and obtained by decrypting the intelligent key, so that a door lock is unlocked. Authentication certification between the door lock main unit and the intelligent key is realized, then the unlocking code is encrypted with the data secret key, bidirectional encryption certification is realized, the safety of unlocking code transmission between the door lock main unit and the intelligent key can be effectively protected, and the safety problem about code disclosure in the use process of a mechanical code lock, an electronic code lock or a fingerprint lock and the like in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent door locks, in particular to an intelligent door lock control method and device. Background technique [0002] At present, with the continuous improvement of people's living standards, more and more attention is paid to security measures, and the household and automotive fields have become an important part of security, such as the existing door locks, car door locks, safe door locks, etc. Most of the coded locks are traditional mechanical coded locks or electronic coded locks or fingerprint locks, etc., and these traditional mechanical coded locks or electronic coded locks or fingerprint locks are unlocked with fixed codes. The mechanical lock key has high stability and low cost. Electronic combination locks and fingerprint locks are easy to use, but they also have great disadvantages, such as mechanical keys are easy to be copied, inconvenient to use, mechanical locks have poor anti-theft an...
