Referring to FIG. 1 , an ultra-wideband sensor-based port logistics container security system (hereinafter referred to as 'system') 100 may include a first sensor device 110 and a second sensor device 130. . Here, the first sensor device 110 is a management terminal installed (attached) to a part of a container to control or manage entry/exit of the container. The second sensor device 130 is a manager terminal having access rights to the container. In addition, both the first sensor device 110 and the second sensor device 130 are UWB sensors.

Specifically, when the encryption key generation mode is executed by a signal input from the outside, the first sensor device 110 generates an encryption key, transmits it to the second sensor device, and transmits an encryption key confirmation request after a preset time. Thus, it is determined whether or not the locking device is locked according to whether the generated encryption key is properly received by the second sensor device.

To this end, the first sensor device 110 may include a first antenna unit 111, a first generation unit 113, a first storage unit 115, and a first control unit 117.

The first antenna unit 111 transmits and receives signals between the second sensor device 130 and other devices.

The first generating unit 113 generates an encryption key as a means for checking access rights to a container.

The first storage unit 115 stores the encryption key generated by the first generation unit 113 as well as various information or data necessary for container security.

When the encryption key generation mode is executed by a signal input from the outside, the first control unit 117 generates an encryption key and transmits it to the second sensor device 130, and then transmits an encryption key confirmation request after a preset time. Depending on whether the previously generated encryption key is received by the second sensor device 130, control is performed to determine whether or not to lock the locking device.

Here, the signal input from the outside may be a signal directly input to the first sensor device 110 by a manager, and for this purpose, the first sensor device 110 may further include an input/output unit (not shown).

On the other hand, when the second sensor device 130 receives an encryption key from the first sensor device 110, temporarily stores the received encryption key, and then receives an encryption key confirmation request from the first sensor device 110. In response, the previously temporarily stored encryption key is transmitted to the first sensor device 110, and when a confirmation notification is received from the first sensor device 110, the temporarily stored encryption key is completely stored.

To this end, the second sensor device 110 may include a second antenna unit 131, a second storage unit 133, and a second control unit 135.

The second antenna unit 131 transmits and receives signals between the first sensor device 110 and other devices.

The second storage unit 133 temporarily stores or completely stores the encryption key received from the first sensor device 110, and also stores various types of information or data required for container security. Here, whether to temporarily store or completely store the encryption key may be determined based on whether or not the first sensor device 110 confirms the encryption key received by the second sensor device 130, and the first sensor device 130 Prior to the decision of the device 110, that is, the first received encryption key is temporarily stored.

When an encryption key is received from the first sensor device 110, the second controller 135 temporarily stores the received encryption key, and when receiving an encryption key confirmation request from the first sensor device 110, the second control unit 135 responds thereto. The previously temporarily stored encryption key is transmitted to the first sensor device 110, and when a confirmation notification is received from the first sensor device 110, control is performed to completely store the temporarily stored encryption key.

Referring to FIG. 2, first, when the encryption key generation mode is executed by the signal input from the outside, the first sensor device 110 generates an encryption key, stores the generated encryption key (S101), The generated encryption key is transmitted to the second sensor device 130 (S105).

At this time, the second sensor device 130 is not a predetermined device, detects an adjacent UWB sensor (device) within a preset range, and sends the detected UWB sensor an encryption key, which is a means of confirming access to the container. It is to decide as a 2-sensor device.

That is, when the first sensor device 110 detects an adjacent (approaching) UWB sensor within a preset range around itself, it regards it as the second sensor device 130 and transmits the encryption key generated in step S101. .

Meanwhile, while the first sensor device 110 performs steps S101 to S105, when the second sensor device 130 detects that the first sensor device 110 generates an encryption key, it waits to receive the encryption key. There may be (S103). However, this is a step that can be omitted and is not an essential step.

Next, when the second sensor device 130 receives the encryption key from the first sensor device 110, it temporarily stores the received encryption key (S107), and the first sensor device 110 sends the second sensor device When a predetermined time elapses from the point at which the encryption key is transmitted to (130), the second sensor device 130 transmits an encryption key confirmation request to the second sensor device 130 to check whether or not the encryption key has been normally received. Do (S109).

Here, the predetermined time is a time preset in the first sensor device 110, and counting is performed based on a preset time from the time when the encryption key is transmitted to the second sensor device 130 and exceeds the preset time. An encryption key confirmation request may be transmitted to the second sensor device 130 .

When the second sensor device 130 receives an encryption key confirmation request from the first sensor device 110, it transmits the temporarily stored encryption key to the first sensor device 110 in response to the request in step S107 (S111). .

When the encryption key is received from the second sensor device 130, the first sensor device 110 checks whether the received encryption key and the encryption key generated in step S101 match, and as a result of the check, the two encryption keys are If matched, immediately after transmitting an encryption key confirmation indicating that the encryption key has been confirmed to the second sensor device 130 (S113), the locking device is executed (engaged) (S115).

Meanwhile, when the encryption key confirmation is received from the first sensor device 110, the second sensor device 130 completely stores the encryption key temporarily stored in step S107 (S117).

After the encryption key between the first sensor device 110 and the second sensor device 130 is generated in this way, when the first sensor device 110 detects an adjacent UWB sensor within a preset range (S119), steps S109 to By performing the same operation as in step S113, it is checked whether encryption keys match (S211).

As a result of the check, if the encryption key between the first sensor device 110 and the second sensor device 130 is matched, the lock is unlocked because the second sensor device 130 has access to the container. And, if the encryption keys between the first sensor device 110 and the second sensor device 130 do not match, the second sensor device 130 does not have access to the container, so the locking device is left as it is. Maintain (S213).

Among the series of processes described above, steps S101 to step 117 are steps in which the first sensor device 110 and the second sensor device 130 generate an encryption key (encryption key generation mode), and steps S119 to S123 are This is a step of determining whether to release the lock based on the encryption key generated between the first sensor device 110 and the second sensor device 130 (unlock mode).

Thereafter, the time from the time of sending the stored encryption key is counted, and if the elapsed time exceeds the threshold (preset time), the second sensor device 130 determines whether the encryption key transmitted in step S207 has been normally received. An encryption key confirmation request for confirmation is transmitted to the second sensor device 130 (S211).

Thereafter, when an encryption key is received from the second sensor device 130 as a response (S213), it is checked whether the encryption key stored in step S203 and the encryption key received in step S213 match (S215).

Subsequently, as a result of checking in step 215, if the encryption key stored in step S203 and the encryption key received in step S213 match, a confirmation notification is sent to the second sensor device 130 (S217), and the locking device is engaged. (S219).

Meanwhile, as a result of checking in step 215, if the encryption key stored in step S203 and the encryption key received in step S213 do not match, each procedure from step S207 is re-performed.
