That is, according to the present invention, the master key device 100 generates the encryption code using the parameter and the machine dependent ID, and assigns the operation control authority to the slave key device 200 using the parameter and the encryption code excluding the machine dependent ID And by verifying the encryption code in the lock system 10, it is possible to prevent tampering or tampering with the encryption code and enhance the security.

In the present invention, the master key device 100 is an electronic key device for registering and using a master key that is an origin of an electronic key. The slave key device 200 receives an operation control right from the master key device 100, And may be an electronic key device for controlling the system 10. At this time, the electronic key used in the slave key device 200 can be referred to as a rental key.

2 is a diagram illustrating a process of transferring a control right and authenticating through a lock system 10 in an electronic key system 20 capable of transmitting a control right of the lock system 10 according to an embodiment of the present invention . Hereinafter, with reference to Figs. 1 and 2, each component of the electronic key system 20 capable of transmitting the control right of the lock system 10 according to the embodiment of the present invention will be described in detail.

The master key device 100 communicates with the lock system 10 to control the operation of the lock system 10 and communicates with other electronic key devices to grant control of the operation of the lock system 10 to other electronic key devices However, the encrypted code can be generated using parameters and machine dependent IDs. The other electronic key device that has been given the operation control authority by the master key device 100 can control the lock system 10 using the lease key and can serve as the slave key device 200. [

The slave key device 200 receives the parameters and the encryption code from the master key device 100 and is given the operation control authority of the lock system 10 and controls the operation of the lock system 10 within the granted authority range Can be controlled. That is, the slave key device 200 is granted the operation control authority only by the parameter and the encryption code except for the machine dependent ID, and can request authentication to the lock system 10 using the parameter and the encryption code.

The lock system 10 receives the parameter and the encryption code from the master key device 100 or the slave key device 200 and uses the machine dependent ID generated by the information of the master key device 100 registered in advance, The verification module 11 can verify the encryption code. The machine dependent ID is generated by using the hardware information of the master key device 100 and constitutes at least two selected from the group including the serial number, the MAC address, and the Bluetooth module ID of the master key device 100 A number, a letter, or a combination of a number and a part of a letter.

By using such a machine dependent ID, theft can be prevented and security can be enhanced.

Further, even if the same master device 100 is used, the machine dependent IDs can be configured differently each time the master key or the machine dependent ID is registered in the lock system 10. [ That is, when the user re-registers the machine dependent ID or the master key, a new machine dependent ID different from the existing registered machine dependent ID can be generated and registered. As described above, since the machine dependent ID can be generated by combining a part of a serial number, a part of a MAC address, and a part of a Bluetooth module ID number, it is possible to combine parts different from each other at registration or add a time stamp or an arbitrary serial A new machine dependent ID can be configured. Accordingly, the user can override the leased key already leased by registering the new machine dependent ID after renting the electronic key, and it is possible to re-register the new master key even if the master key is leaked once, thereby improving the safety.

In some embodiments, the parameter may further include a revocation authority for the lease key. That is, the new rental key is transmitted to the slave key device 200 which is already using the rental key, and the parameter including the cancel right is transferred, so that the existing rental key can be automatically canceled. Accordingly, it is possible to cancel the individual rental key without re-registering the master key or the machine dependent ID after borrowing the rental key, thereby improving user convenience.

In addition, the operation control authority can be restricted to control the operation of the lock system 10 only when another electronic key device satisfies the usage constraint included in the parameter. That is, the slave key device 200 can control the operation of the lock system 10 only when various usability restriction conditions such as the use period of the rental key, the use frequency, and the use area are satisfied.
