Smart lock with MAC address and control method of the smart lock

Abstract

The invention discloses a smart lock with an MAC address and a control method of the smart lock. After a smart phone applies to a cloud server for the unlocking right of the smart lock with the current MAC address through a wireless network environment, a time-limited unlocking secrete key K is obtained; the smart phone reads the MAC address A and the current value R of a random number generator built in the smart lock through a Bluetooth communication function; the smart lock carries out encryption operation on the MAC address A, a built-in secrete key K and the random number R, thus obtaining an unlocking password P2; after the smart phone carries out encryption operation on the MAC address A, the random number R and the unlocking secrete key K, thus obtaining an unlocking password P1, and the P1 is sent to the smart lock through the Bluetooth communication function; and when the smart lock judges that the P1 is equal to the P2, an electric locking mechanism is unlocked, thus finishing once unlocking action. The smart lock does not need to be in communication connection with the cloud server, and as long as there is a power line, the smart lock can work; burying a pipeline is also unnecessary, therefore, the structure of the system is simplified, the response speed is accelerated, the construction difficulty and the construction cost are reduced, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the field of access control, in particular to an intelligent lock with a MAC address in an access control management system and a control method thereof. Background technique [0002] The access control system is an entrance and exit management control system, which is widely used in large office spaces and residential areas. Common access control systems include: password access control system, non-contact IC card (inductive IC card) access control system, biological access control system based on fingerprint, iris, palm type and other biometric identification. [0003] The existing access control management method is to connect each access control device in the form of a bus or a network. Each access control device reads the information of a specific identity medium (access control card) and confirms the information to the host through a data transmission channel (bus or network). After authenticity, act accordingly. Since ...

Problems solved by technology

This access control management method is an extension of the traditional access control management method. It just replaces the access control card with a smart phone. During the project installation, it still cannot get rid of the process of laying pipelines and connecting various pipelines (power lines, data lines). If the cloud server fails or the number of smart locks is large, and the cloud server does not respond in time, the entire system will be paralyzed
