A method and system for opening and closing locks based on lock connectors

Abstract

The invention discloses an opening and closing method and system based on a lock connector. In this method, the lock body end is connected to the server end through the lock connector and the mobile terminal. When the lock is unlocked, it is initiated by the lock connector, and then the random code is generated by the lock body, and then the random code is sent to the server. The server calculates the authorization code by combining the random code with the connection key, and then sends the authorization code to the lock body, and the lock body calculates the verification code by combining the random code with the connection key, and compares whether the verification code is consistent with the authorization code. When the two match, perform unlocking. After the unlocking is completed, the lock connector saves the unlocking record. When locking, it is initiated by the lock connector. If there is a corresponding lock body in the unlock record, a lock command is sent, otherwise, a lock authorization is requested from the server, and a lock command is sent to the lock body after authorization is obtained. The method of the present invention avoids the one-way control of the lock body by the server, but determines whether to unlock through interaction between the two parties, so that 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
