For detailed connection establishment management procedures, see Figures 2 and 3 below.

FIG. 2 shows a connection establishment management method according to an embodiment of the present invention for establishing a connection between the main device 300 and the wireless access device 100. It should be noted that although not specifically stated, the following connection establishment management method can be performed by the processing unit in the wireless access device 100 and the processing unit 340 in the main device 300.

After the main device 300 is powered on, in step S202, the processing unit 340 of the main device 300 first determines whether a previous wireless connection exists between the main device 300 and the wireless access device 100. The master device 300 can determine whether a previous wireless connection already exists by checking its connection status. In some embodiments, the master device 300 may first receive a broadcast packet from the wireless access device 100 that includes a first encrypted identification information, and decrypt the first encrypted identification information to obtain a corresponding wireless access device included therein. A first identification data of 100 is used to learn the device data of the wireless access device 100, and then according to the first identification data, it is determined whether there is a previous wireless connection with the wireless access device 100. It is reminded that if the main device 300 has previously established a wireless connection with the wireless access device 100, the main device 300 can record the relevant connection information and connection parameters used by the wireless connection, and then does not Will re-establish the connection. Assuming that a wireless connection exists, in step S204, the main device 300 will establish the main device 300 and the wireless access device according to the connection parameters (such as bandwidth requirements and other service quality requirements) used in the previous wireless connection. Wireless connection between 100.

Conversely, when it is determined that the previous wireless connection does not exist, in step S206, indicating that the previous connection failed or the first connection with the wireless access device 100, the host device 100 transmits the wireless packet containing the encrypted identification information to the wireless. The device 100 is accessed, and then step S208 is performed to continuously monitor whether any manufacturer identification data containing the identifiable wireless access device and the encrypted identification information of the device function data are detected. The encrypted identification information sent by the main device 300 includes the manufacturer data of the main device 300 and its device function data. For example, if the main device 300 is an A-brand gaming machine, the manufacturer information of the main device 300 is "A" and the device function data is "game machine". In some embodiments, a particular algorithm (eg, hashing) may be used to encrypt the vendor information of the host device and its device function information to generate encrypted identification information.

When the main device 300 detects the encrypted identification information including the identifiable wireless access device data through the wireless interface 310, in step S210, the main device 300 decrypts the encrypted identification information by using the specific algorithm (for example, hashing method). The wireless access device identification information is obtained, and the wireless access device identification information, such as the manufacturer data of the wireless access device 100 and the device function data thereof, is displayed on the screen of the display unit 330 of the main device 300 through the display unit 330. on. The user inputs an identification code of the wireless access device 100 and an identification code of the main device 300 through the input unit 320 (eg, a remote controller, a button, a keyboard, a mouse, etc.) on the screen of the display unit 330 of the main device 300. To establish an encrypted wireless connection encrypted in AES mode. Therefore, in step S212, the main device 300 transmits an encrypted identification information to the data corresponding to the identifiable wireless access device corresponding to the identification code of the wireless access device 100 received by the input unit 320 and the identification code of the primary device. The wireless access device 100 is configured to establish a wireless connection with the wireless access device 100. In this step, both the wireless access device 100 and the host device 300 must verify their own unique identification code from the wireless packet sent by the other party to start establishing a secure wireless connection. Among them, the unique identification code can be its product serial number. For example, the wireless access device 100 can verify whether the serial number of the wireless access device entrained in the wireless packet sent by the primary device 300 is the same as the serial number of the product, and the primary device 300 can verify the wireless sent by the wireless access device 100. Whether the device identification code entrained in the packet is the same as its product serial number, and if the verification result is the same, the connection between the wireless access device 100 and the main device 300 is allowed to be established. On the other hand, if there is an inconsistency, it means that the wireless access device 100 is not a device that allows connection, and thus the connection establishment procedure with the wireless access device 100 is ended. Through the foregoing connection establishment management method, the manual input step of the connection can be simplified, the connection between the devices can be quickly established, and the connection is allowed because the identification code of the input is required to be correct, and the illegal device or the user can be effectively filtered. Wired request.

After the connection establishment between the main device 300 and the wireless access device 100 is completed, any of the slave devices 410 or 420 may request to establish a connection with the host device 300 through the wireless access device 100.

FIG. 3 shows a connection establishment management method for establishing a connection between the slave device 410 and the wireless access device 100 in accordance with an embodiment of the present invention. It should be noted that although not specifically stated, the following connection establishment management method can be performed by a processing unit (not shown) in the slave device 410 and the processing unit 340 in the master device 300.

When a slave device is powered on, for example, from the device 410, the slave device 410 first determines whether a previous wireless connection exists between the slave device 410 and the wireless access device 100, as in step S302. Assuming that a previous wireless connection exists between the slave device 410 and the wireless access device 100, in step S304, the slave device 410 will use the connection parameters (eg, bandwidth requirements and other quality of service requirements) used according to the previous connection. ) to establish a wireless connection with the wireless access device 100.

Conversely, when it is determined that there is no previous wireless connection between the slave device 410 and the wireless access device 100, in step S306, the slave device 410 transmits a wireless packet containing the encrypted identification information to the wireless access device 100, and then executes Step S308. The encrypted identification information sent from the device 410 includes the manufacturer information of the slave device 410 and its device function information. For example, if the slave device is an A-brand TV set, the slave manufacturer's product information is "A" and its device function data is "TV". Similarly, in some embodiments, the processing unit of slave device 410 may utilize a particular algorithm (eg, hashing) to encrypt the vendor profile of the device and its device function data to obtain encrypted identification information. After the wireless access device 100 detects the encrypted identification information sent by the slave device 410, the wireless access device 100 decrypts the encrypted identification information by using the specific algorithm (for example, hashing method), in step S308, to obtain the The slave device recognizes the information and sends the slave device identification information to the master device 300 through the wireless interface, so that the display unit of the master device 300 displays the identification information of the slave device 410. Then, the user inputs an identification code of the wireless access device 100 and an identification code of the slave device through an input unit (eg, a remote controller, a button, a keyboard, a mouse, etc.) on the screen of the main device 300 to establish a AES encrypts encrypted wireless connections. Then, in step S310, the main device 300 transmits an encrypted identification information to the wireless access device 100 corresponding to the identification code of the wireless access device 100 received by the input unit 330 and the identification code of the slave device 410 to establish the slave device. 410 is connected to a wireless connection of the wireless access device 100. In this step, both the wireless access device 100 and the slave device 410 must verify their own unique identification code from the wireless packets sent by the host device 300 to begin to establish a secure wireless connection. The unique identification code may be its product serial number, but the invention is not limited thereto. For example, the wireless access device 100 can verify whether the serial number of the wireless access device entrained in the wireless packet sent by the primary device 300 is the same as the serial number of the product, and the secondary device 410 can verify the wireless packet sent by the primary device 300. Whether the entrained slave device serial number is the same as its product serial number, and if the verification results are the same, the connection between the slave device 410 and the wireless access device 100 is allowed to be established, so that the slave device 410 is added to the original sharing. In the network. On the other hand, if an inconsistency is found, it means that the slave device 410 is not allowed to connect, and therefore the connection between the slave device 410 and the wireless access device 100 is rejected. After the connection between the device 410 and the wireless access device 100 is completed, the host device 300 can control the slave device 410 or perform data sharing through the wireless access device 100. Similarly, the slave device 420 can also establish a connection with the wireless access device 100 according to the foregoing connection establishment management method, and then join the wireless access device 100 in the shared network.

In some embodiments, in order to transmit the encrypted identification information, at least one information element (IE) may be added to enclose the encrypted identification information. The information element is added to the beacon packet to transmit encrypted identification information and encrypted connection parameters. As shown in FIG. 4A, the information element 600 can include a plurality of fields including an element identification code field 610, a length information field 620, a device type field 630, and an encrypted identification information field 640. The length information field 620 indicates the length of the information element 600, and the device type field 630 indicates whether the information element 600 is issued by the main device 300, the wireless access device 100, or the slave devices 410, 420. The encrypted identification information field 640 includes the aforementioned device vendor data 642 and its device function data 644, as shown in FIG. 4B. Therefore, the master device, the wireless access device 100 or the slave device can receive or transmit the information element 600 and obtain the encrypted identification information from the information element 600 for subsequent determination. In addition, an additional information element can be added to enclose the encrypted connection parameters. As shown in FIG. 4C, the information element 700 can include a plurality of fields including an element identification code field 710, a length information field 720, a device type field 730, and an encrypted connection parameter field. 740, wherein the length information field 720 represents the length of the information element 700, and the device type field 730 indicates whether the information element 700 is issued by the main device 300, the wireless access device 100, or the slave devices 410, 420. The encrypted connection parameter field 740 contains the device type identification code of both parties to be wired and the product serial number of both parties. For example, if the main device 300 wants to establish a connection with the wireless access device 100, the connection parameter field 740 will include the device identification code and the unique identification code corresponding to the wireless access device 100 and include the corresponding device. Device identification code and unique identification code. In some embodiments, the information element 700 can further include another connection parameter field (not shown) that is used to indicate the connection conditions required for the device corresponding to the device type field 730, such as bandwidth requirements. The priority order or other quality of service (QoS) conditions, etc., and the master device 300, the wireless access device 100 or the slave devices 410, 420 can receive or transmit the information element 700 and obtain the encrypted connection parameters from the information element 700. Make judgments or automatically set connection conditions. Therefore, the user does not need to manually set it.

FIG. 5 shows a connection establishment management method according to an embodiment of the present invention, which is applicable to a connection establishment management system. In the present embodiment, the connection establishment management method can be applied to the connection establishment management system 10 shown in FIG. 1.

In step S502, the wireless access device 100 periodically broadcasts a packet including a first encrypted identification information, where the first encrypted identification information includes a first identification data corresponding to the wireless access device 100, such as a wireless access device. 100 manufacturer information and device function data. Similarly, the wireless access device 100 can entrain the first encrypted identification information in the aforementioned information element 600 for transmission. Next, in step S504, the main device 300 receives the packet from the wireless access device 100, decrypts the first encrypted identification information to obtain the first identification data, and displays the first identification data through the display unit. Then, in step S506, the main device 300 generates a second encrypted identification information according to a first identification code and a second identification code received by the input unit, and transmits the second encrypted identification information to the wireless access device 100. The first identification code corresponds to the wireless access device 100, and the second identification code corresponds to the main device 300. For example, if the main device is an A-brand TV set and the wireless access device is a wireless labeling device of the A-brand model B, the screen of the television will be detected according to the first identification data. A message from the wireless pick-up device of model A model B. When the user sees this message, it can decide whether to establish a connection. If yes, the product serial number (first identification code) of the wireless access device of the A-brand model B can be input through the input unit (for example, a TV remote control). And the product serial number (second identification code) of the main device itself. Thereafter, the primary device may encrypt the input first identification code and the second identification code with a specific algorithm to generate second encrypted identification information.

After receiving the second encrypted identification information, in step S508, the wireless access device 100 determines whether to establish the primary device according to the second encrypted identification information and the unique identification code of the wireless access device 100 and the unique identification code of the primary device 300. 300 wireless connection. In this step, the wireless access device 100 can decrypt the second encrypted identification information according to the decryption algorithm corresponding to the algorithm used by the host device 300, and obtain the product serial number of the wireless access device input by the user ( a first identification code) and a product serial number (second identification code) of the main device itself, and determining whether the input product serial number meets the unique identification code of the wireless access device 100 (ie, the product serial number) and the uniqueness of the main device 300 Identifier. When the first identification code meets the unique identification code of the wireless access device 100 and the second identification code conforms to the unique identification code of the main device 300, it indicates that the main device 300 and the wireless access device 100 are allowed to establish a connection, and therefore, the wireless The access device 100 determines to establish a wireless connection with the main device 300. Conversely, if the first identification code does not meet the unique identification code of the wireless access device 100 or the second identification code does not meet the unique identification code of the main device 300, it indicates that the main device 300 and the wireless access device 100 are not allowed to establish a connection. The line, therefore, the wireless access device 100 refuses to establish a wireless connection with the primary device 300 or ignores its connection establishment requirements. Similarly, the wireless access device 100 and the main device 300 can further automatically set the connection parameters according to the service quality conditions such as the predetermined connection parameters, such as the bandwidth requirement, to achieve the purpose of automatic setting.

Similarly, the wireless access device 100 can further receive a packet from the slave device 410 and transmit the packet to the master device 300, wherein the packet includes a third encrypted identification information associated with a third identification data of the slave device 410. After receiving the packet, the main device 300 decrypts the third encrypted identification information to obtain the third identification data, and displays the third identification data through the display unit. Next, the main device 300 generates a fourth encrypted identification information according to a third identification code and a fourth identification code received by the input unit, and transmits the fourth encrypted identification information to the wireless access device 100, wherein the third identification code Corresponding to the wireless access device 100, the fourth identification code corresponds to the slave device 410. After receiving the fourth encrypted identification information, the wireless access device 100 may determine whether to establish a wireless connection with one of the slave primary devices according to the fourth encrypted identification information. When the third identification code conforms to the unique identification code (eg, product serial number) of the wireless access device and the fourth identification code conforms to the unique identification code of the slave device 410, the wireless access device 100 determines to establish a wireless connection with the slave device 410. .

In some embodiments, after the automatic connection establishment is completed, the master device/slave device and the wireless access device 100 can further generate an encryption key using the verified product serial number, and utilize the generated encryption key. The key and specific encryption algorithms such as hashing are encrypted to generate encrypted identification information or encrypted connection parameters to ensure data security after the connection and to avoid establishing connections with unintended devices. In some embodiments, the wireless access device 100 can further dynamically change the encryption key according to the network time of the connection, so that the encryption key is less likely to be cracked, thereby increasing the security of the data on the connection. Sex.

It is to be noted that, in some embodiments, after the connection is successfully established, a remote control device (not shown) can also remotely control the main device 300 through the network 500 and the wireless access device 100, thereby Relevant management and monitoring of each connected slave device (e.g., slave devices 410 and 420). For example, the remote control device can access the main device 300 in the network through the network device 200 and the wireless access device 100, and then monitor the connected devices in the home network through the host device 300. Status and operating conditions.
