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.
