2 schematically shows a pairing scheme of an electronic device and a lighting device according to an embodiment of the present invention. In the embodiment of the present invention, in a situation where there are three electronic devices, i.e., the first illuminating device 210-1, the second illuminating device 210-2, and the third illuminating device 210-3, It is assumed that the first illuminating device 200 wants to pair with the second illuminating device 210-2. However, the embodiment of the present invention can be equally applied in a situation where at least one illumination device exists.

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

The electronic device 100 that has obtained the identification data of the second illuminating device 210-2 transmits the obtained identification data to the peripheral first illuminating device 210-1, the second illuminating device 210-2, To the device 210-3 (step 222). For example, the electronic device 200 may include identification data obtained in an advertisement message transmitted through an advertising channel, and may include peripheral first illumination device 210-1, second illumination device 210-2, 3 lighting apparatus 210-3. According to another embodiment, in addition to the advertisement message transmitted through the advertisement channel, the electronic device 200 may include identification data in other types of messages transmitted through other channels, 2 lighting device 210-2, and the third lighting device 210-3.

Each of the first illuminating device 210-1, the second illuminating device 210-2 and the third illuminating device 210-3 can perform the authentication process based on the identification data received from the electronic device 200 (Step 224). That is, each of the first illuminating device 210-1, the second illuminating device 210-2, and the third illuminating device 210-3 compares the identification data received from the electronic device 200 with its own identification data So that the electronic device 200 can determine whether the lighting device to be paired is the self. For example, the second illuminating device 210-2 compares the identification data received from the electronic device 200 with the identification data of the second illuminating device 210-2 to confirm that the identification data thereof is the same as the identification data thereof, The controller 200 determines that the lighting device to be paired is the own device. Accordingly, the second illuminating device 210-2 can transmit a response signal to the electronic device 200 to perform a pairing process. As another example, each of the first illuminating device 210-1 and the third illuminating device 210-3 may compare identification data received from the electronic device 200 with its own identification data, It is determined that the identification data is different and the electronic device 200 judges that the lighting device to be paired is not itself. Accordingly, each of the first illuminating device 210-1 and the third illuminating device 210-3 may not perform any response operation.

In addition, the electronic device 200 and the second illuminator 210-2 may generate a Temporary Key (TK) based on the identification data (e.g., the RGB value of the light or the period value of the illumination) And can be used for the pairing process. For example, the electronic device 200 and the second illuminator 210-2 can perform link layer encryption at the time of pairing using the TK generated based on the identification data.

3A shows 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 is generated in step 301. FIG. The Bluetooth pairing event can be generated by user input or by 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 an application execution for controlling a lighting device. As a more detailed example, in an application for controlling a lighting device supporting Bluetooth, when a pairing menu with a lighting device or a pairing mode is selected, it can be detected that a Bluetooth pairing event is generated.

When the occurrence of the 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 Bluetooth pairing event is detected, the electronic device 200 may automatically drive the camera to photograph the peripheral illumination device and transmit a pairing request signal to the peripheral illumination devices. For example, as shown in FIG. 4, the electronic device 200 may generate a pairing request signal (I4) in which the IO capability is keyboard / Display 411 and the Man-In-The-Middle attack (MITM) 410). Here, the IO capability indicates whether the electronic device 200 is capable of inputting and outputting. In the embodiment of FIG. 4, the electronic device 200 is capable of inputting via the keyboard and displaying the screen. In addition, MITM indicates whether or not the TK key can be used to protect against a man-in-the-middle attack. In the embodiment of FIG. 4, the electronic device 200 indicates that the man-in-the-middle attack is possible using the TK key.

Then, the electronic device 200 captures the illumination device in step 305 to acquire the identification data. For example, the electronic device 200 can capture a captured image (still image) by capturing an illuminating device through an automatically driven camera and extracting the RGB values of the illuminating device from the captured image. As another example, the electronic device 200 may acquire a moving image by photographing the illuminating device for a predetermined period of time through an automatically driven camera, and analyze a plurality of images included in the acquired moving image to obtain a period value of illumination . Here, the electronic device 200 can acquire a captured image or a moving image by photographing the lighting apparatus by the user's input while the camera is automatically driven.

Thereafter, the electronic device 200 proceeds to step 307 to transmit the identification data obtained by the photographing to the lighting device. For example, the electronic device 200 may include an RGB value of the illuminating device obtained from the captured image, or a period value of the illuminating device obtained from the moving image, in the advertisement message to provide at least one illuminating device 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 at the electronic device 200. As shown in FIG. 4, the pairing response signal 420 may have the IO capability of keyboard / Display 421 and the Man-In-The-Middle attack (MITM) may be Yes 422. Here, the IO capability indicates whether input and output of the illumination device 210 are possible, and the MITM indicates whether or not it is possible to protect against the meson attack using the TK key. The illumination device 210 can not input the TK through the keyboard and can not receive the input of the TK. However, according to the embodiment of the present invention, capability indicates keyboard / Display 421, and MITM indicates Yes. This is to generate a TK value based on the identification data of the lighting device and proceed with pairing in a passkey entry mode. Here, the pass key and tree mode is one of the known Bluetooth pairing modes.

Then, the electronic device 200 generates the TK based on the identification data. For example, the electronic device 200 may generate a six-digit TK based on the RGB value or illumination period of the illuminator. According to an embodiment, the electronic device 200 may multiply the illumination period by any fixed value (k) to produce a TK value comprised of six digits. According to another embodiment, the electronic device 200 generates a 2-digit value of the 6-digit TK value using the R value among the RGB values of the lighting device, as shown in FIG. 5, The other 2-digit value can be generated, and the remaining 2-digit value can be generated using the B value. According to an embodiment, the electronic device 200 may change RGB to a six digit TK using a known color quantization scheme. For example, the electronic device 200 may change RGB to TK by using a color quantization method that converts each of the R value, the G value, and the B value represented by the step 255 into an arbitrary level (e.g., 10 levels) . For example, known color quantization schemes include uniform color quantization, popularity algorithms, median cut algorithms, and Octree algorithms. The uniform color quantization is a method of dividing R, G, and B values at regular intervals. For example, uniform color quantization is a method of dividing RGB values into 256 steps by dividing R value and G value into 8 levels and dividing B value into 4 levels. The popularity algorithm is a method of generating a list of the number of colors and colors obtained from the scanned image, and sorting the colors based on the number of times in the generated list to select the top 256 ones. The median cut algorithm method converts the axes of R, G, and B values into a 3D planar view, and then separates the number of desired colors. The Octree algorithm generates a tree with a depth of N and adjusts the depth of the tree to select the desired number of colors.

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 to perform link layer encryption, and transmits the TK value and / or the STK value Based LTK (Long Term Key) value to be used for communication between the electronic device 200 and the illuminating device 210.

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

FIG. 3B shows a pairing procedure of a lighting apparatus 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 informs the electronic device 200 of the identification data of the lighting device in step 323. FIG. For example, the lighting device 210 may generate a random RGB value or cycle value based on its MAC address for pairing with the electronic device 200 without being paired with the electronic device 200 And output the illumination according to the generated RGB value or cycle value. Since the RGB value or the period value is generated based on the MAC address of the lighting device 210, the RGB value or the period value can be used as identification data for identifying the lighting device 210 among the plurality of lighting devices.

Thereafter, the illumination device 210 receives the identification data from the electronic device 200 in step 325, and checks whether the identification data received from the electronic device 200 matches the identification data of the electronic device 200 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 the period value of the illumination received from the electronic device 200 is the same as the illumination period value generated in step 323. [ When the identification data received from the electronic device 200 and the identification data of the electronic device 200 do not match, the lighting device 210 recognizes that the electronic device 200 desires to pair with another lighting device other than itself, The procedure according to the embodiment can be terminated.

When the identification data received from the electronic device 200 matches the identification data of the electronic device 200, the lighting device 210 recognizes that the electronic device 200 wants to pair with the electronic device 200. In step 329, And transmits a response signal. The pairing response signal 420 may be the keyboard / display 421 and the Man-In-The-Middle attack (MITM) may be Yes 422 as shown in FIG. Here, the IO capability indicates whether input and output of the illumination device 210 are possible, and the MITM indicates whether or not it is possible to protect against the meson attack using the TK key. The illuminating device 210 according to the embodiment of the present invention can not input the IO capability of the pairing response signal 420, keyboard / Display (421), and set MITM to Yes. This is to generate a TK value based on the identification data of the lighting device 210 and proceed with pairing in a passkey entry mode.

Thereafter, the lighting device 210 generates a TK based on the identification data in step 331. [ For example, the lighting device 210 may generate the TK using the RBG value or the lighting period generated based on the MAC address of the lighting device 210. [ In accordance with an embodiment, the lighting device 210 may multiply the illumination period by any fixed value (k) to produce a TK value comprised of six digits. Here, any fixed value k may be a predetermined value with the electronic device 200. According to another embodiment, as shown in FIG. 5, the illuminating device 210 generates a 2-digit value of the 6-digit TK value using the R value among the RGB values of the illuminating device, The other 2-digit value can be generated, and the remaining 2-digit value can be generated using the B value. In accordance with an embodiment, the lighting device 210 may change RGB to a six-digit TK using a known color quantization scheme. Here, the lighting device 210 may generate the TK value using the same color quantization scheme as the electronic device 200. [

Then, the lighting device 210 proceeds to step 333 and performs a pairing process with the electronic device 200 based on the TK value generated. For example, the lighting apparatus 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 transmits the TK value and / or the STK value Based LTK (Long Term Key) value to be used for communication between the electronic device 200 and the illuminating device 210.

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

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

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

When the occurrence of the 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 Bluetooth pairing event is detected, the electronic device 200 may automatically drive the camera to photograph the peripheral illumination device and transmit a pairing request signal to the peripheral illumination devices. For example, as shown in FIG. 4, the electronic device 200 may generate a pairing request signal (I4) in which the IO capability is keyboard / Display 411 and the Man-In-The-Middle attack (MITM) 410).

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

If the type of the illumination device to be paired is a color type, the electronic device 200 may acquire an image of the illuminating device taken in step 607, and may acquire RGB data from the image obtained in step 609. For example, the electronic device 200 may acquire a still image including the illumination device through photography and extract an RGB value representing the color of the illumination device within the acquired image. Then, the electronic device 200 proceeds to step 611 and transmits the obtained RGB data to the lighting device 210, and then proceeds to step 613. At this time, the electronic device 200 may transmit the advertisement message including the RGB data through the advertisement channel. Accordingly, the advertisement message can be transmitted to a plurality of illuminating devices located in the periphery of the electronic device 200. [

On the other hand, if the type of the lighting device to be paired is white type, the electronic device 200 photographs the lighting device for a preset time period in step 617, and proceeds to step 619 to acquire periodic data from the moving picture do. For example, the electronic device 200 may analyze the image of the illumination device taken for a preset time (e.g., 10 seconds) and acquire the period value of the illumination based on the number of times the illumination is turned on / off for a preset time can do. Then, the electronic device 200 proceeds to step 621 and transmits the acquired period data to the lighting device 210, and then proceeds to step 613. At this time, the electronic device 200 may transmit periodic data to the advertisement message through the advertisement channel. Accordingly, the advertisement message can be transmitted to a plurality of illuminating devices located in the periphery of the electronic device 200. [

The electronic device 200 checks in step 613 whether or not a pairing response signal is received from the lighting device 210. [ If a pairing response signal is received, the electronic device 200 proceeds to step 615 and generates a TK value based on the RGB data or the period data. For example, when the electronic device 200 transmits RGB data to the lighting device 210 and receives a pairing response signal in response thereto, the electronic device 200 generates a TK value based on the RGB data using the color quantization method . As another example, if the electronic device 200 transmits periodic data to the lighting device 210 and receives a pairing response signal in response thereto, the periodic data may be multiplied by a predetermined value to generate a TK value.

In step 615, the electronic device 200 performs authentication and link layer encryption based on the generated TK value to perform a pairing procedure. 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 to perform link layer encryption, and transmits the TK value and / or the STK value Based LTK (Long Term Key) value to be used for communication between the electronic device 200 and the illuminating device 210. Thereafter, the electronic device 200 ends the pairing procedure according to the embodiment of the present invention.

On the other hand, when the pairing response signal is not received, the electronic device 200 proceeds to step 623 and checks whether a signal requesting the white type of pairing progress is received from the lighting device. For example, after transmitting the RGB data, the electronic device 200 checks whether a signal requesting the white type pairing progress is received within a predetermined time period instead of the pairing response signal. If a signal requesting the white type pairing process is received, the electronic device 200 returns to step 617 and executes the following steps again.

On the other hand, when the electronic device 200 does not receive a signal requesting a pairing process of a white type, that is, a signal requesting a pairing progress with the pairing response signal is not received within a predetermined time, the electronic device 200 It is determined that the pairing has failed and the pairing procedure according to the embodiment of the present invention ends. At this time, the electronic device 200 may display a message indicating that the pairing fails on the screen.

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

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

If it is a color type lighting device, the lighting device 210 randomly generates an RGB value based on the MAC address in step 705, and performs an illumination function based on the RGB value generated in step 707. For example, the illumination device 210 may output illumination of a color corresponding to the generated RGB value. Then, the lighting device 210 receives RGB data from the electronic device in step 709. [ For example, the lighting device 210 may receive the advertisement message via an advertisement channel and extract RGB data from the advertisement message. Then, the lighting apparatus 210 checks whether the RGB data received from the electronic device 200 in step 711 and the RGB values generated in step 705 match. If the received RGB data and the generated RGB value match, the electronic device 200 determines that the lighting device to be paired is itself, and the lighting device 210 transmits a pairing response signal to the electronic device in step 713 send. 4, the IO capability may be the keyboard / Display 421 and the Man-In-The-Middle attack (MITM) may be Yes 422. In this case, For example, the lighting device 210 can not input or display a screen through the keyboard and can not input a TK. However, according to the embodiment of the present invention, the IO capability of the pairing response signal 420 may be input to the keyboard / Display 421, and set MITM to Yes. This is to generate a TK value based on the RGB value or the illumination period value of the lighting device 210 and proceed with pairing in a passkey entry mode.

Then, the lighting apparatus 210 proceeds to step 715 and generates a TK value based on the identification data, that is, RGB data. For example, the lighting device 210 may change RGB to a six-digit TK using a known color quantization scheme. As shown in FIG. 5, the lighting apparatus 210 generates a 2-digit TK value using the R value among the RGB values of the lighting apparatus based on the color quantization scheme, Value of the 6-digit TK value and another 2-digit value of the 6-digit TK value using the B value. Here, the lighting device 210 may generate the TK value using the same color quantization scheme as the electronic device 200. [

Then, the lighting device 210 proceeds to step 717 and performs a pairing process with the electronic device 200 based on the generated TK value. For example, the lighting apparatus 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 transmits the TK value and / or the STK value Based LTK (Long Term Key) value to be used for communication between the electronic device 200 and the illuminating device 210.

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

If it is determined in step 711 that the received RGB data does not match the generated RGB value, the lighting apparatus 210 proceeds to step 727 and checks whether the RGB values are mismatched by using the filter. For example, if the lighting device 210 includes a filter for a particular 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 in 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 values do not match, the lighting apparatus 210 determines whether or not the values of the remaining color series except for the color series filtered by the filter included in the lighting apparatus 210 match It is possible to judge whether or not the RGB values are mismatched by using the filter. For example, when the illumination device 210 uses an R-series filter, it is determined whether the G value and the B value except the R value among the received RGB data and the generated RGB value match. If the R value of the received RGB data is inconsistent with the R value of the generated data but the G value of the received RGB data matches the G value of the generated data and the B value of the received data and B If the values match, the lighting device 210 may determine that the RGB values are mismatched by using the filter. On the other hand, if the R value of the received RGB data is inconsistent with the R value of the generated data, the G value of the received RGB data does not match the G value of the generated data, or the B value of the received data and B If 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 are inconsistent due to the use of the filter, the lighting apparatus 210 proceeds to step 729 to request the electronic device 200 to proceed with the pairing of the white type, and then proceeds to step 719 to re-execute the following steps .

On the other hand, if the RGB values are not mismatched due to the use of the filter, the lighting device 210 breaks the lighting device to be paired by the electronic device 200 into a non-self, and performs the pairing procedure according to the embodiment of the present invention And terminates.

On the other hand, if it is determined in step 703 that the lighting device 210 is a white type lighting device, the roughing device 210 randomly generates a periodic value based on the MAC address in step 719, To perform a lighting function. For example, the illumination device 210 may control the illumination to be turned on / off a number of times corresponding to the period value generated during a predetermined time during outputting the illumination. Thereafter, the lighting device 210 receives the period data from the electronic device in step 723. [ For example, the lighting device 210 may receive the advertisement message via the advertisement channel and extract the periodic data from the advertisement message. Thereafter, the lighting apparatus 210 checks whether the period data received from the electronic device 200 in step 725 and the period value generated in step 719 coincide with each other. If the received periodic data does not match the generated periodic value, the lighting device 210 determines that the lighting device to be paired by the electronic device 200 is not its own, Exit the procedure.

On the other hand, when the received period data matches the generated period value, the lighting apparatus 210 determines that the lighting apparatus to be paired by the electronic apparatus 200 is the own apparatus, and transmits a pairing response signal to the electronic apparatus in step 713 send. 4, the IO capability may be the keyboard / Display 421 and the Man-In-The-Middle attack (MITM) may be Yes 422. In this case, For example, the lighting device 210 can not input or display a screen through the keyboard and can not input a TK. However, according to the embodiment of the present invention, the IO capability of the pairing response signal 420 may be input to the keyboard / Display 421, and set MITM to Yes. This is to generate a TK value based on the RGB value or the illumination period value of the lighting device 210 and proceed with pairing in a passkey entry mode.

Thereafter, the lighting apparatus 210 proceeds to step 715 to generate the TK value based on the identification data, i.e., the period data of the illumination. For example, the lighting device 210 may generate the TK value by multiplying the period value by a predetermined value. Then, the lighting device 210 proceeds to step 717 and performs a pairing process with the electronic device 200 based on the generated TK value. For example, the lighting apparatus 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 transmits the TK value and / or the STK value Based LTK (Long Term Key) value to be used for communication between the electronic device 200 and the illuminating device 210.

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

3A, 3B, 6, and 7, when the occurrence of the Bluetooth pairing event is detected, the electronic device 200 automatically drives the camera and transmits a pairing request signal. However, according to another embodiment, after acquiring the identification data, the electronic device 200 may include identification data in the pairing request signal and transmit a pairing request signal including the identification data. In another embodiment, the electronic device 200 may transmit identification data to peripheral lighting devices and may transmit a pairing request signal to the peripheral lighting devices separately from the identification data. According to another embodiment of the present invention, when the pairing request signal is transmitted after acquiring the identification data, the illumination device 210 may perform the identification data notification function or notify the identification data at every predetermined time. For example, in the unpaired state, a predetermined RGB value or a predetermined period of time may be output according to a preset method, and a randomly generated RGB value or cycle may be output can do. As another example, in the unpaired state, it is possible to always output lights at randomly generated RGB values or cycles based on their MAC addresses.
