server, and a user can download the virtual key through a communication network; when the user wants to open a gate, unlocking requests are sent to a gate lock, a car lock and the like with
Bluetooth modules, and the virtual key is downloaded; the lock node can verify the legality of the virtual key through inspecting the virtual key so as to unlock for the
current user; an unlocking message can be generated during each-time unlocking, is transmitted back to the server through
Bluetooth after being processed by a corresponding
algorithm and is saved in the virtual key to generate a new virtual key. The virtual key provided by the invention can be used in intelligent buildings in modern wisdom cities, can also be used in bicycles, drawers and the like, has the biggest advantages that the keeping of the key is simplified, and the use efficiency of the key is improved, and has the characteristics of high in safety and convenient to use.
