The invention discloses a dynamic password-based unlocking system and a dynamic password-based unlocking method. The unlocking system comprises a server, a lock control device and an electric controllock; the lock control device has a unique identification code; the server communicates with the lock control device through wireless communication connection; when the current time reaches password updating time, if the wireless communication connection is not disconnected, the lock control device generates a dynamic password and transmits the dynamic password and the unique identification code to the server; the server saves the dynamic password which is received recently and transmits the dynamic password to a mobile terminal; after an unlocking password is input into the lock control device through the mobile terminal, the lock control device compares the unlocking password with the dynamic password; if the unlocking password is consistent with the dynamic password, the electric control lock is controlled to unlock. The dynamic password-based unlocking system and the dynamic password-based unlocking method can improve security, prevent a user from wasting time and improve user experience.
Description
technical field [0001] The invention relates to the technical field of remote unlocking, in particular to an unlocking system and an unlocking method based on a dynamic password. Background technique [0002] At present, commonly used access control locks, cabinet door locks, anti-theft locks, etc. all use mechanical locks with metal keys. These locks have defects such as inconvenient carrying of keys, easy loss of keys, and malicious preparation of keys, so the security is low. In order to improve security, electronically controlled locks have appeared in recent years. These electronically controlled locks use coded keyboards, access control cards, etc. as unlocking keys. Among them, the electronically controlled locks using coded keyboards are widely promoted because they do not need to carry access control cards for unlocking. [0003] However, the electronically controlled lock that adopts the password keyboard is fixed due to the password, and once it is maliciously sto...
