Locking and unlocking method and system based on lock connector

Abstract

The invention discloses a locking and unlocking method and system based on a lock connector. The method comprises the steps that a lock side is connected with a server side through the lock connectorand a mobile terminal; during unlocking, the lock connector initiates unlocking, then, the lock side generates a random code, and the random code is sent to the server side. The server side performs calculation with the combination of the random code and a connection secret key to obtain an authorization code, then, the authorization code is sent to the lock side, the lock side performs calculation with the combination of the random code and the connection secret key to obtain a verification code, whether the verification code and the authorization code are consistent or not is judged throughcomparison, and when the two codes are consistent, unlocking is performed. After unlocking is completed, the lock connector stores an unlocking record. During locking, the lock connector initiates locking, if the corresponding lock side exists in the unlocking record, a locking instruction is sent, if not, locking authorization is requested from the server side, and after authorization is obtained, the locking instruction is sent to the lock side. The method avoids one-way control of the server side over the lock side, whether or not to unlock is judged through interaction of the two parties,and unlocking is safer.

Description

technical field [0001] The present invention relates to electronic locks. Background technique [0002] Under the prior art, during the unlocking process of the electronic lock, there is usually a controller role. For example, in the use of biometric technology, the biological information provided by the controller, such as fingerprints, irises, etc., the electronic lock judges whether the information provided by the controller belongs to the authorized person, and if the judgment is consistent, the lock will be executed. For another example, in a password lock, the controller inputs the password, and the electronic lock judges whether the input password belongs to the authorized person, and if the judgment is consistent, unlocking is performed. Also in the electronic lock controlled by the background, the background acts as the controller, and the controller provides the authorization code necessary for unlocking, and then the electronic lock judges whether the authorizati...

Problems solved by technology

The disadvantage of this one-way control is that the electronic lock cannot determine whether the controller is a forgery, that is, the controller may be illegal, but because the authorization verification information provided by it is legal in the electronic lock, the electronic lock is considered legal

Obviously, there are security risks in this way
