Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an Internet of Things device network configuration system and method using NFC technology. Background Art

[0002] The Internet of Things (IoT) is an important trend in the development of science and technology in recent years. Its core is to connect various objects to the network to achieve intelligent control and management. With the increasing popularity of IoT devices, such as smart homes, smart wearables, and smart medical care, users have higher expectations for the experience of device connection and configuration. They hope to have a way to quickly, simply, and safely add newly purchased or adjusted devices to the existing system.

[0003] Traditional network configuration methods, such as Wi-Fi and Bluetooth connections, are widely used, but users often face a series of challenges. First, these methods usually require users to perform multiple steps, such as entering passwords, selecting networks, and waiting for devices to search and connect, which not only consumes users' time but may also lead to operational errors. Second, due to the wide communication range of these network configuration methods, they are vulnerable to multiple security threats such as man-in-the-middle attacks and counterfeit device attacks, increasing the risk of user data leakage, especially in smart home environments, which may involve user privacy and physical safety.

[0004] In addition, as mobile devices, especially smartphones and tablets, become increasingly important in people's lives, it becomes crucial to provide users with an easy way to work with these devices.

[0070]

[0071]

[0072] NFC tag production

[0073] To ensure the integrity and security of data, encryption or signing methods are used to ensure that the data in the NFC tag is not tampered with during transmission. NFC tags should contain:

[0074] 1. Record#1: Write a URL that supports the iOS Universal Links function and write the device identification information into the URL so that the specific device can be located in the subsequent network configuration process. For example: https: / / nfc.rinoiot.com / {appId} / nfc-control? uuid={device uuid}&pid={product id}

[0075] 2. Record#2: Enter the Android APP package name, such as com.rinoiot.smart.

[0076] Usage Process

[0077] 1. The user brings the NFC module on the mobile device close to the NFC tag on the IoT device.

[0078] 2. The mobile device system recognizes the NFC tag and determines whether the application is installed on the device. If not, the app store is opened to prompt the user to install the application. If already installed, the application is opened to prompt the user to install the application.

[0079] 3. After the user opens the application according to the prompt, the application completely obtains the URL information in the NFC tag and parses the key ID data.

[0080] 4. The application sends the acquired key ID data to the cloud, and the cloud returns the Bluetooth identification information of the device.

[0081] 5. The application finds nearby IoT devices based on the Bluetooth identification information returned by the cloud and sends the network configuration information to the device.

[0082] 6. After receiving the network configuration data, the IoT device connects to the network and completes the network configuration process.

[0083] Security

[0084] 1. Short-distance feature: The working distance of NFC technology is usually within 4 cm, which greatly reduces the risk of being read by illegal devices.

[0085] 2. Data Integrity and Encryption:

[0086] – Data in NFC tags can be digitally signed to ensure data integrity during transmission. Any unauthorized modification of the data can be easily detected.

[0087] – Encrypt data stored on NFC tags using AES or other advanced encryption standards to ensure data privacy.

[0088] 3. Secure channel: Establish a secure channel between mobile phones and IoT devices to ensure that the network configuration information is not stolen or tampered with during transmission.

[0089] 4. Dynamic Verification:

[0090] – When the mobile phone reads the NFC tag, the cloud server can dynamically generate a one-time verification code, which the mobile app must enter to proceed to the next step, thus ensuring the security of the network configuration process.

[0091] – The information in an NFC tag can be changed periodically or based on specific conditions, making it dynamic and reducing the risk of illegal copying or tampering.

[0092] 5. Two-way authentication:

[0093] – During the network configuration process, not only does the mobile phone authenticate the IoT device, but the IoT device also authenticates the mobile phone to ensure that both parties are legitimate and trustworthy.

[0094] 6. Anti-replay attack:

[0095] – Use timestamp or random number technology to ensure that each network configuration request is unique, preventing attackers from capturing and resending network configuration requests;

[0096] 7. Device tampering detection:

[0097] – Sensors can be installed inside the device to detect any physical tampering with the device, such as attempts to open the device or access internal circuits. Once tampering is detected, the device can immediately sound an alarm and stop working;

[0098] 8. Permission control:

[0099] – During the network configuration process, the cloud server can perform permission checks on requests to ensure that the requests come from authorized users. In addition, network configuration permission levels can be set, such as administrators and ordinary users, to limit the network configuration capabilities of different users;

[0100] The above measures can further ensure that the NFC-based IoT device configuration experience is not only simple, efficient, but also secure. This is essential to ensure the privacy of user data and the integrity of the device.

[0101] The detailed steps are as follows:

[0102] NFC identification: The user uses the NFC module on the mobile device to approach the NFC tag on the IoT device.

[0103] Device response: The mobile device automatically recognizes the NFC tag and triggers related events. At this time, the system will check the URL or package name on the tag to determine whether the corresponding application needs to be launched or downloaded.

[0104] Data parsing: After the application is launched, it will read the URL information of the NFC tag. It will parse the device ID and other related information from the URL.

[0105] Communicate with the cloud: The application sends the device ID parsed from the NFC tag to the cloud server. The cloud server returns the network configuration information of the corresponding IoT device based on the device ID.

[0106] Complete network configuration: The application completes the device network configuration process based on the network configuration information received from the cloud server.

[0107] Here is an example:

[0108] Consider a user who has purchased a smart desk lamp with a built-in NFC module. The user wants to connect this desk lamp to the Wi-Fi at home. The user only needs to activate the NFC function of the mobile phone and bring it close to the NFC tag area of ​​the desk lamp. The mobile phone automatically reads the NFC data, opens the corresponding application, and the user enters the password of the home Wi-Fi in the application. The application sends the password to the desk lamp, and the desk lamp automatically completes the Wi-Fi connection. The whole process is simple and fast.

[0109] Through this specific implementation, the present invention realizes a network configuration method for Internet of Things devices using NFC technology, ensuring the simplicity, speed and security of network configuration.

[0110] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
