Cabinet access control system and method based on dynamic password

Abstract

A cabinet access control system based on a dynamic password comprises a cloud platform, a communication controller, an intelligent lock and a mobile device, the communication controller and the mobiledevice are both in wireless connection with the cloud platform, the communication controller is in wired or wireless connection with the intelligent lock, and the mobile device is in wired or wireless connection with the intelligent lock. The invention further discloses a control method of the cabinet access control system based on the dynamic password. According to the invention, the unlocking modes of a contact type or non-contact type IC card and the like of the existing lock are abandoned, and a user does not need to carry the unlocked IC card or user card and the like at any time. Password verification is carried out in the intelligent lock, a secret key is stored in an exclusive area of the intelligent lock, and when an operator inputs a dynamic password through a key or a touch screen of the intelligent lock, the dynamic password is effective once and needs to be input within the effective duration of the password, leakage does not need to be worried about, and safety performance is high.

Description

technical field [0001] The invention relates to a cabinet access control system and method based on a dynamic password. Background technique [0002] During the use of outdoor cabinets such as optical boxes, a large number of construction workers are involved in unpacking operations, and the key management problem has become a difficulty and pain point in daily management. In the few cases of intelligent transformation at present, the traditional access control method is generally adopted, and the opening of the lock is controlled by setting a white list or setting a temporary password in the lock. The biggest weakness of this method is the concept that the locks do not have a key. Relevant personnel of the factory who are familiar with the system can easily open all the locks, which brings great risks to the security of the customer's system. [0003] In the prior art, most of the access control is opened by swiping a card. Even if there is an authentication terminal, the ...

Problems solved by technology

Some smart locks also involve dynamic factors and keys, but their dynamic factors are time synchronization or event synchronization factors, and the dynamic factor update method is to increase or decrease the same value, which has low security performance, and most of the keys are prefabricated by lock manufacturers , and the locks of the same model have the same key, the manufacturer can open the access control, and the security is poor
