Claims (5)

A lock system supporting two-factor authentication comprising a lock configured in a storage box and a smart key inserted into the lock to unlock the lock.
A smart key including a housing having an authentication module storing authentication information and a first short range communication unit supporting short range communication, and a physical key structure configured at one side of the housing and inserted into the locking device;
A lock device comprising a key bundle portion having a cylinder that is inserted into the key structure of the smart key to change the locking state of the locking device according to the rotation operation, and a solenoid portion for limiting the movement of the cylinder configured in the key bundle portion. ; And
A control module for confirming the authentication information by short-range communication with the first short-range communication unit of the smart key, and when the authentication is successful, operating the solenoid unit to unlock the lock device through the key structure
Including;
The lock is
The solenoid portion further includes a stopper rod for limiting the movement of the cylinder configured in the key assembly,
A hook portion configured to be adjacent to the key bundle portion and to be caught by the stopper rod to limit rotation of the cylinder configured at the key bundle portion,
The control module operates the stopper rod through the solenoid part when authentication is successful according to confirmation of the authentication information so that the locking portion is not caught by the stopper rod so that the locking device is unlocked by the key structure. Featuring a two-factor lockout system.
The method according to claim 1,
The short range communication unit of the smart key is composed of a first winding unit,
The locking device further includes a second winding unit which receives current from the control module and generates an induced current in the first winding unit through electromagnetic induction with the first winding unit when adjacent to the first winding unit.
The authentication module of the smart key operates by receiving an induction current from the first winding part to transmit the authentication information to the control module through the first and second winding parts. .
The method according to claim 2,
The smart key is connected to the second winding unit to accumulate the induction current, and further comprising a power storage unit for supplying power to the authentication module.
delete The method according to claim 1,
And a sensor unit which rotates together with the cylinder by the rotation of the key structure and transmits a sensing signal according to the rotation position.
The control module is a locking system supporting dual authentication, characterized in that for determining the lock state of the locking device based on the sensing signal of the sensor unit.
