2 schematically illustrates a method for pairing an electronic device and a lighting device according to an embodiment of the present invention. In an embodiment of the present invention, in a situation where three electronic devices, that is, the first lighting device 210-1, the second lighting device 210-2, and the third lighting device 210-3 exist, the electronic device A case in which 200 intends to pair with the second lighting device 210 - 2 will be described. However, the embodiment of the present invention may be equally applied to a situation in which at least one lighting device exists.

Referring to FIG. 2 , the electronic device 200 according to an embodiment of the present invention photographs a second lighting device 210 - 2 to be paired with. At this time, the electronic device 200 may acquire data for identifying the second lighting device 210 - 2 through photographing of the second lighting device 210 - 2 (step 220 ). For example, the electronic device 200 may obtain a red green blue (RGB) value of the second lighting device 210 - 2 from a photographed image of the second lighting device 210 - 2 . As another example, the electronic device 200 captures the second lighting device 210-2 for a predetermined time to obtain a cycle value indicating the number of times the lighting output of the second lighting device 210-2 is turned on/off. can For example, the electronic device 200 may measure the number of times the lighting device is turned on/off for 10 seconds. That is, the electronic device 200 may obtain the RGB value or the lighting period value of the lighting device as identification data of the second lighting device 210 - 2 .

The electronic device 100, which has obtained the identification data of the second lighting device 210-2, uses the obtained identification data to the peripheral first lighting device 210-1, the second lighting device 210-2, and the third lighting device. It is transmitted to the device 210-3 (step 222). For example, the electronic device 200 includes the obtained identification data in an advertisement message transmitted through an advertisement channel, and includes the first ambient lighting device 210-1, the second lighting device 210-2, and the second lighting device 200-1. 3 may be transmitted to the lighting device 210-3. According to another embodiment, in addition to the advertisement message transmitted through the advertisement channel, the electronic device 200 includes the identification data in another type of message transmitted through another channel to include the first ambient lighting device 210-1, the first It may be transmitted to the second lighting device 210-2 and the third lighting device 210-3.

Each of the first lighting device 210-1, the second lighting device 210-2, and the third lighting device 210-3 may perform an authentication process based on the identification data received from the electronic device 200. There is (step 224). That is, each of the first lighting device 210-1, the second lighting device 210-2, and the third lighting device 210-3 compares the identification data received from the electronic device 200 with their own identification data. Thus, the electronic device 200 may determine whether the lighting device to be paired with is itself. For example, the second lighting device 210 - 2 compares the identification data received from the electronic device 200 with its own identification data, and confirms that the received identification data and its identification data are the same, and the electronic device 200 determines that the lighting device to be paired is itself. Accordingly, the second lighting device 210 - 2 may transmit a response signal to the electronic device 200 to perform a pairing process. As another example, each of the first lighting device 210-1 and the third lighting device 210-3 compares the identification data received from the electronic device 200 with its own identification data, and compares the received identification data with its own identification data. It is confirmed that the identification data is different, and the electronic device 200 determines that the lighting device to be paired is not itself. Accordingly, each of the first lighting device 210 - 1 and the third lighting device 210 - 3 may not perform any response operation.

Additionally, the electronic device 200 and the second lighting device 210 - 2 generate a temporary key (TK) based on identification data (eg, RGB value of lighting or periodic value of lighting) used for authentication. It can be created and used in the pairing process. For example, the electronic device 200 and the second lighting device 210 - 2 may perform link layer encryption during pairing using a TK generated based on identification data.

3A illustrates a pairing procedure of an electronic device according to an embodiment of the present invention.

Referring to FIG. 3A , the electronic device 200 detects whether a Bluetooth pairing event occurs in step 301 . The Bluetooth pairing event may be generated by a user input or execution of a specific application. For example, in an embodiment of the present invention, a Bluetooth pairing event may be generated by a user input for controlling a specific lighting device or execution of an application for controlling a lighting device. As a more detailed example, in an application for controlling a lighting device supporting Bluetooth, when a pairing menu or a pairing mode with a lighting device is selected, it can be detected that a Bluetooth pairing event occurs.

When the occurrence of a Bluetooth pairing event is detected, the electronic device 200 automatically drives the camera in step 303 and transmits a pairing request signal. For example, when the occurrence of a Bluetooth pairing event is detected, the electronic device 200 may automatically drive a camera to photograph the ambient lighting device and transmit a pairing request signal to the ambient lighting devices. For example, as shown in FIG. 4 , the electronic device 200 has a pairing request signal ( 410) may be transmitted. Here, IO capability indicates whether the electronic device 200 is capable of input and output. In the embodiment of FIG. 4 , the IO capability indicates that the electronic device 200 can input through a keyboard and display a screen. In addition, MITM indicates whether protection from a man-in-the-middle attack is possible using the TK key. In the embodiment of FIG. 4 , the electronic device 200 indicates that a man-in-the-middle attack is possible using the TK key.

Thereafter, the electronic device 200 acquires identification data by photographing the lighting device in step 305 . For example, the electronic device 200 may acquire a captured image (still image) by photographing a lighting device through an automatically driven camera, and extract RGB values of the lighting device from the captured image. As another example, the electronic device 200 may acquire a moving picture by photographing a lighting device for a predetermined time through an automatically driven camera, and may obtain a period value of illumination by analyzing a plurality of images included in the obtained moving picture. . Here, the electronic device 200 may acquire a captured image or a moving picture by photographing the lighting device according to a user's input in a state in which the camera is automatically driven.

Thereafter, the electronic device 200 proceeds to step 307 and transmits the identification data obtained by photographing to the lighting device. For example, the electronic device 200 includes the RGB value of the lighting device obtained from the captured image or the period value of the lighting device obtained from the video in the advertisement message, and sends it to at least one lighting device located in the vicinity through the advertisement channel. send.

Thereafter, the electronic device 200 receives a pairing response signal from the lighting device. For example, the electronic device 200 may receive a pairing response signal from the lighting device 210 photographed by the electronic device 200 . As shown in FIG. 4 , in the pairing response signal 420 , IO capability may be keyboard/Display 421 , and Man-In-The-Middle attack (MITM) may be Yes 422 . Here, IO capability indicates whether input and output of the lighting device 210 are possible, and MITM indicates whether protection from a man-in-the-middle attack is possible using the TK key. Substantially, the lighting device 210 is a situation in which input and screen display through the keyboard is not possible and cannot receive TK, but in an embodiment of the present invention, the IO of the pairing response signal 420 by the control of the lighting device 210 capability may indicate keyboard/Display (421), and MITM may indicate Yes. This is to perform pairing in a passkey entry mode by generating a TK value based on the identification data of the lighting device. Here, the passkey entry mode is one of known Bluetooth pairing modes.

Thereafter, the electronic device 200 generates a TK based on the identification data. For example, the electronic device 200 may generate a six-digit TK based on an RGB value or an illumination period of the lighting device. According to an embodiment, the electronic device 200 may generate a TK value composed of 6 digits by multiplying the illumination period by an arbitrary fixed value k. According to another embodiment, as shown in FIG. 5 , the electronic device 200 generates two-digit values among six-digit TK values by using R values among RGB values of the lighting device, and uses the G values. You can create another two-digit value, and use the B value to create the other two-digit value. According to an embodiment, the electronic device 200 may change RGB to 6-digit TK using a known color quantization method. For example, the electronic device 200 converts RGB to TK by using a color quantization method that converts each of the R, G, and B values expressed in steps 255 into arbitrary levels (eg, 10 levels). can For example, known color quantization schemes include uniform color quantization, a popularity algorithm, a median cut algorithm, and an Octtree algorithm. Uniform color quantization is a method of dividing each of the R, G, and B values at regular intervals. For example, the uniform color quantization divides the R value and the G value into 8 stages, and divides the B value into 4 stages to divide the RGB values into a total of 256 stages. The popularity algorithm creates a list of colors and the number of colors obtained from the scanned image, and selects the top 256 colors by sorting the colors based on the number of times in the generated list. The median cut algorithm method converts the axes of R, G, and B values to a 3D plane view, and then separates the desired number of colors. The octree algorithm creates a tree with a depth of N, and selects the desired number of colors by adjusting the depth of the tree.

Thereafter, the electronic device 200 performs a pairing process with the lighting device based on the TK value generated in step 313 . For example, the electronic device 200 performs an authentication process based on the TK value, generates a Short Term Key (STK) value based on the TK value, performs link layer encryption, and performs link layer encryption on the TK value and/or the STK value. can be used for communication between the electronic device 200 and the lighting device 210 by generating a Long Term Key (LTK) value based on .

Thereafter, the electronic device 200 may end the pairing procedure according to an embodiment of the present invention.

3B illustrates a pairing procedure of a lighting device according to an embodiment of the present invention.

Referring to FIG. 3B , the lighting device 210 receives a pairing request signal from the electronic device 200 in step 321 , and performs a function for notifying the identification data of the lighting device to the electronic device 200 in step 323 . For example, in a state in which the lighting device 210 is not paired with the electronic device 200 , a random RGB value or period value is generated based on its MAC address for pairing with the electronic device 200 . It can be created and output lighting according to the generated RGB value or period value. Here, since the RGB value or the period value is generated based on the destination of the lighting device 210 , it may be used as identification data for distinguishing the corresponding lighting device 210 from among a plurality of lighting devices.

Thereafter, the lighting device 210 receives identification data from the electronic device 200 in step 325 , and checks whether the identification data received from the electronic device 200 matches its own identification data in step 327 . For example, the lighting device 210 may compare whether the RGB value received from the electronic device 200 is the same as the RGB value generated in step 323 . As another example, the lighting device 210 may compare whether a cycle value of the illumination received from the electronic device 200 is the same as the illumination cycle value generated in step 323 . When the identification data received from the electronic device 200 and the identification data of the lighting device 210 do not match, the lighting device 210 recognizes that the electronic device 200 wants to pair with a lighting device other than itself, The procedure according to the embodiment may be terminated.

When the identification data received from the electronic device 200 and its identification data match, the lighting device 210 recognizes that the electronic device 200 wants to pair with itself, and proceeds to step 329 for pairing with the electronic device. Send a response signal. As shown in FIG. 4 , the pairing response signal 420 may have an IO capability keyboard/Display 421 and a Man-In-The-Middle attack (MITM) Yes 422 . Here, IO capability indicates whether input and output of the lighting device 210 are possible, and MITM indicates whether protection from a man-in-the-middle attack is possible using the TK key. Substantially, the lighting device 210 is a situation in which input and screen display through the keyboard is not possible and the TK cannot be input, but the lighting device 210 according to an embodiment of the present invention provides the IO capability of the pairing response signal 420 . Set to keyboard/Display(421), and set MITM to Yes. This is to perform pairing in a passkey entry mode by generating a TK value based on the identification data of the lighting device 210 .

Thereafter, the lighting device 210 generates a TK based on the identification data in step 331 . For example, the lighting device 210 may generate a TK using an RBG value or an illumination period generated based on its own address. According to an embodiment, the lighting device 210 may generate a TK value composed of six digits by multiplying the lighting period by an arbitrary fixed value k. Here, the arbitrary fixed value k may be a value previously agreed with the electronic device 200 . According to another embodiment, as shown in FIG. 5 , the lighting device 210 generates a 2-digit value out of a 6-digit TK value by using the R value among the RGB values of the lighting device, and uses the G value. You can create another two-digit value, and use the B value to create the other two-digit value. According to an embodiment, the lighting device 210 may change RGB to 6-digit TK using a known color quantization method. Here, the lighting device 210 may generate the TK value using the same color quantization method as the electronic device 200 .

Thereafter, the lighting device 210 performs a pairing process with the electronic device 200 based on the generated TK value in step 333 . For example, the lighting device 210 performs an authentication process based on the TK value, generates a Short Term Key (STK) value based on the TK value, performs link encryption, and then performs link encryption, TK value and/or STK value can be used for communication between the electronic device 200 and the lighting device 210 by generating a Long Term Key (LTK) value based on .

Thereafter, the lighting device 210 may end the pairing procedure according to an embodiment of the present invention.

6 illustrates a detailed procedure for performing pairing in an electronic device according to an embodiment of the present invention.

Referring to FIG. 6 , the electronic device 200 detects whether a Bluetooth pairing event occurs in step 601 . The Bluetooth pairing event may be generated by a user input or execution of a specific application. For example, in an embodiment of the present invention, a Bluetooth pairing event may be generated by a user input for controlling a specific lighting device or execution of an application for controlling a lighting device. As a more detailed example, in an application for controlling a lighting device supporting Bluetooth, when a pairing menu or a pairing mode with a lighting device is selected, it can be detected that a Bluetooth pairing event occurs.

When the occurrence of a Bluetooth pairing event is detected, the electronic device 200 automatically drives the camera in step 603 and transmits a pairing request signal. For example, when the occurrence of a Bluetooth pairing event is detected, the electronic device 200 may automatically drive a camera to photograph the ambient lighting device and transmit a pairing request signal to the ambient lighting devices. For example, as shown in FIG. 4 , the electronic device 200 has a pairing request signal ( 410) may be transmitted.

Thereafter, the electronic device 200 confirms the type of the lighting device to be paired. For example, the electronic device 200 may determine whether the lighting device to be paired is a color-type lighting device or a white-type lighting device. The electronic device 200 may identify the type of the lighting device to be paired by the user's input. For example, the electronic device 200 may display an interface requesting to select a type of lighting device to be paired on the screen, and may identify the type of lighting device to be paired by a user input. At this time, when it is confirmed that the lighting device to be paired is of the color type, the electronic device 200 may drive or switch the camera shooting mode to the photo shooting mode for acquiring a still image, and it is determined that the lighting device to be paired is a white type. When confirmed, the camera shooting mode may be driven or switched to a moving picture shooting mode for acquiring a moving image. As another example, the electronic device 200 may display an interface for requesting to select a photographing method of a lighting device to be paired, and confirm the type of the lighting apparatus to be paired by the user's selection of a photographing method. For example, when the photo shooting mode is selected, it may be determined that the type of the lighting device to be paired is a color, and when the video shooting mode is selected, it may be determined that the type of the lighting device to be paired is the white type. As another example, the electronic device 200 may analyze an image input by automatic camera driving to determine whether the lighting device to be paired is a color type or a white type.

If the type of the lighting device to be paired is the color type, the electronic device 200 may obtain an image obtained by photographing the lighting device in step 607 and obtain RGB data from the obtained image in step 609 . For example, the electronic device 200 may acquire a still image including the lighting device through photographing, and extract RGB values representing the color of the lighting device from the obtained image. Thereafter, the electronic device 200 proceeds to step 611 and transmits the obtained RGB data to the lighting device 210 , and proceeds to step 613 below. In this case, the electronic device 200 may include RGB data in the advertisement message and transmit it through the advertisement channel. Accordingly, the advertisement message may be transmitted to a plurality of lighting devices located in the vicinity of the electronic device 200 .

7 illustrates a detailed procedure for performing pairing in a lighting device according to an embodiment of the present invention.

Referring to FIG. 7 , the lighting device 210 receives a pairing request signal from the electronic device 200 in step 701 , and checks the type of the lighting device in step 703 . For example, the lighting device 210 may determine whether it is a color-type lighting device or a white-type lighting device.

When the lighting device 210 is a color-type lighting device, the lighting device 210 randomly generates RGB values based on the beer element in step 705 , and proceeds to step 707 and performs a lighting function based on the generated RGB values. For example, the lighting device 210 may output lighting of a color corresponding to the generated RGB value. Thereafter, the lighting device 210 receives RGB data from the electronic device in step 709 . For example, the lighting device 210 may receive an advertisement message through an advertisement channel and extract RGB data from the advertisement message. Thereafter, the lighting device 210 checks whether the RGB data received from the electronic device 200 in step 711 and the RGB value generated in step 705 match. If the received RGB data and the generated RGB value match, the electronic device 200 determines that it is the lighting device to be paired with, and the lighting device 210 sends a pairing response signal to the electronic device in step 713 . send. Here, in the pairing response signal 420 , as shown in FIG. 4 , IO capability may be keyboard/Display 421 , and Man-In-The-Middle attack (MITM) may be Yes 422 . For example, the lighting device 210 is a situation in which input and screen display through the keyboard are not possible and TK cannot be received, but according to an embodiment of the present invention, the IO capability of the pairing response signal 420 is keyboard/ Display 421 may be set, and MITM may be set to Yes. This is to perform pairing in a passkey entry mode by generating a TK value based on the RGB value or the lighting period value of the lighting device 210 .

Thereafter, the lighting device 210 generates a TK value based on identification data, that is, RGB data in step 715 . For example, the lighting device 210 may change RGB to 6-digit TK using a known color quantization method. As a more detailed example, the lighting device 210 generates two-digit values among the six-digit TK values by using the R values among the RGB values of the lighting device as shown in FIG. 5 based on the color quantization method, and G The value can be used to generate other two-digit values among the six-digit TK value, and the remaining two-digit values can be generated from the six-digit TK value by using the B value. Here, the lighting device 210 may generate the TK value using the same color quantization method as the electronic device 200 .

Thereafter, the lighting device 210 performs a pairing process with the electronic device 200 based on the generated TK value in step 717 . For example, the lighting device 210 performs an authentication process based on the TK value, generates a Short Term Key (STK) value based on the TK value, performs link encryption, and then performs link encryption, TK value and/or STK value can be used for communication between the electronic device 200 and the lighting device 210 by generating a Long Term Key (LTK) value based on .

Meanwhile, when it is determined in step 711 that the received RGB data and the generated RGB values do not match, the lighting device 210 proceeds to step 727 and checks whether the RGB values do not match by using the filter. For example, when the lighting device 210 includes a filter for a specific color, the lighting output color of the lighting device 210 may be different from the RGB value generated by the MAC address. In this case, the RGB value obtained by photographing the lighting device 210 by the electronic device 200 is different from the RGB value generated by the MAC address of the lighting device 210 . Accordingly, when the received RGB data and the generated RGB value do not match, the lighting device 210 determines whether the values of the remaining color series except for the color series filtered by the filter included in the lighting device 210 match. By judging, it can be determined whether the RGB values are inconsistent by using the filter. For example, when the lighting device 210 uses the R-series filter, it is determined whether the G value excluding the R value and the B value match among the received RGB data and the generated RGB values. If the R value of the received RGB data and the R value of the generated data do not match, but the G value of the received RGB data and the G value of the generated data match, the B value of the received data and the B value of the generated data When the values match, the lighting device 210 may determine that the RGB values do not match by using the filter. On the other hand, the R value of the received RGB data and the R value of the generated data do not match, the G value of the received RGB data and the G value of the generated data do not match, or the B value of the received data and the B value of the generated data When the values do not match, the lighting device 210 may determine that the RGB values are not mismatched by using the filter.

If the RGB values do not match due to the use of the filter, the lighting device 210 proceeds to step 729 to request the electronic device 200 to proceed with white type pairing, and proceeds to step 719 to perform the following steps again. .

On the other hand, if the RGB values do not match by using the filter, the lighting device 210 breaks the lighting device that the electronic device 200 wants to pair with is not itself, and performs the pairing procedure according to the embodiment of the present invention. quit

On the other hand, as a result of the inspection in step 703, when the roughing device 210 is a white type lighting device, it randomly generates a cycle value based on the beer cow in step 719, and proceeds to step 721 based on the generated cycle value. to perform the lighting function. For example, the lighting device 210 may control the lighting to be turned on/off as many times as the number of times corresponding to the period value generated for a preset time while outputting the lighting. Thereafter, the lighting device 210 receives period data from the electronic device in step 723 . For example, the lighting device 210 may receive an advertisement message through an advertisement channel, and extract period data from the advertisement message. Thereafter, the lighting device 210 checks whether the period data received from the electronic device 200 in operation 725 matches the period value generated in operation 719 . If the received period data and the generated period value do not match, the lighting device 210 determines that the lighting device to be paired with the electronic device 200 is not itself, and pairing according to an embodiment of the present invention Terminate the procedure.

On the other hand, when the received period data and the generated period value match, the lighting device 210 determines that the lighting device to be paired with the electronic device 200 is itself, and sends a pairing response signal to the electronic device in step 713 . send. Here, in the pairing response signal 420 , as shown in FIG. 4 , IO capability may be keyboard/Display 421 , and Man-In-The-Middle attack (MITM) may be Yes 422 . For example, the lighting device 210 is a situation in which input and screen display through the keyboard are not possible and TK cannot be received, but according to an embodiment of the present invention, the IO capability of the pairing response signal 420 is keyboard/ Display 421 may be set, and MITM may be set to Yes. This is to perform pairing in a passkey entry mode by generating a TK value based on the RGB value or the lighting period value of the lighting device 210 .

Thereafter, the lighting device 210 generates a TK value based on identification data, that is, period data of lighting, in step 715 . For example, the lighting device 210 may generate the TK value by multiplying the period value by a preset value. Thereafter, the lighting device 210 performs a pairing process with the electronic device 200 based on the generated TK value in step 717 . For example, the lighting device 210 performs an authentication process based on the TK value, generates a Short Term Key (STK) value based on the TK value, performs link encryption, and then performs link encryption, TK value and/or STK value can be used for communication between the electronic device 200 and the lighting device 210 by generating a Long Term Key (LTK) value based on .
