[0053] Example 1

[0054] Figure 1 This is a flowchart of a wireless communication method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where wireless communication is performed between a Bluetooth sensor and a vehicle-mounted system. The method can be executed by a Bluetooth sensor, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0055] S110: In response to a sensor-triggered event, obtain service information and device key.

[0056] Among them, the sensor trigger event is the event that triggers the Bluetooth sensor to broadcast data, and the service information is the service-related information that the Bluetooth sensor needs to broadcast. To prevent the broadcast information from being forged, anti-counterfeiting information can be added to the broadcast content, and the device key is the key required to calculate this anti-counterfeiting information.

[0057] Optionally, the Bluetooth sensor can be configured in external electronic devices such as mobile phones, computers, and smartwatches. Sensor trigger events can be of various types, such as conditions like temperature or time reaching set values, or user actions like button presses or clicks on the electronic device. In response to a sensor trigger event, the Bluetooth sensor can obtain corresponding business information from the electronic device. For example, if the sensor trigger event is that the current temperature has reached a set value, the corresponding business information could be the current temperature data.

[0058] In this embodiment, the Bluetooth sensor can communicate wirelessly with the vehicle's infotainment system. Before communication, the Bluetooth sensor and the vehicle's infotainment system can authenticate each other through security authentication methods to generate a device key for calculating anti-counterfeiting information, which is pre-stored on the Bluetooth sensor and the vehicle's infotainment system respectively.

[0059] S120. Generate a broadcast message in a set format based on the device key and service information.

[0060] The broadcast message includes an anti-counterfeiting field. The broadcast message is a message broadcast by the Bluetooth sensor.

[0061] In this embodiment, the format of the broadcast message is predefined. Figure 2 This is a schematic diagram of a broadcast message format provided by an embodiment of the present invention. As shown in the figure, the broadcast message consists of 8 fields, and the names and number of bytes occupied by each field are as follows: identity (2 bytes), product id (2 bytes), flag (1 byte), device id (4 bytes), seq (2 bytes), random (2 bytes), object (n bytes), and nonce (2 bytes). Among them, device id is the device identification information contained in the broadcast message, and nonce is the anti-counterfeiting field contained in the broadcast message. The description of each field in the broadcast message is shown in Table 1.

[0062] Table 1. Explanation of each field in the broadcast message.

[0063]

[0064]

[0065] Optionally, the method for generating a broadcast message in a set format based on the device key and service information may be: generating a first message field containing service information and device identification information according to the set broadcast format; generating an anti-counterfeiting field based on the first message field and the device key; and using the combination of the first message field and the anti-counterfeiting field as the broadcast message.

[0066] Specifically, a broadcast message consists of two parts: a first message field containing service information and an anti-spoofing field. When generating a broadcast message, the first message field, containing service information and device identification information (device id), can be generated first according to the prescribed broadcast format. Taking the broadcast format specified in Table 1 as an example, the first message field is the field preceding the nonce field. When generating the first message field, the Bluetooth sensor can fill in the required information for each field sequentially into the corresponding positions according to the format requirements.

[0067] By setting the format of broadcast messages, different types of Bluetooth sensors can send broadcast messages in a standard format, which facilitates unified management on the vehicle's infotainment system. Furthermore, by using the device key to generate an anti-counterfeiting field, it is possible to prevent unauthorized devices from forging broadcast messages.

[0068] Furthermore, the method for generating the anti-counterfeiting field based on the first message field and the device key can be as follows: combine the first message field and the device key, and combine them with a block encryption algorithm to obtain the target message authentication code; perform hash processing on the target message authentication code to obtain the anti-counterfeiting field.

[0069] Specifically, the block cipher algorithm used in this scheme can be AES-CMAC (Cryptographic Message Authentication Code). AES-CMAC is an encryption algorithm used to generate a message authentication code (MAC) from a given message and a symmetric key, providing data integrity and authentication. This algorithm is based on AES (Advanced Encryption Standard) block cipher and operates in CBC-MAC (Cryptographic Block Chaining Message Authentication Code) mode. AES-CMAC processes the input data (message) by repeatedly using the AES algorithm, generating a fixed-length MAC using the key, typically 128 bits (16 bytes). Due to its efficiency and security, AES-CMAC is commonly used in resource-constrained environments.

[0070] Figure 3 This is a schematic diagram illustrating the generation process of an anti-counterfeiting field according to an embodiment of the present invention. The broadcast message in the diagram follows the format of Table 1. As shown in the figure, when generating the anti-counterfeiting field, the generated first message field and the locally stored device key are obtained respectively. The first message field is fields 1-7 in the broadcast message. The first message field is divided into blocks, each block being 128 bits (16 bytes). If the length of the first message field is not a multiple of 128 bits, it is padded with 0; if the message length is already a multiple of 128 bits, no padding is performed. After block division, each block is encrypted using AES and iteratively processed using an XOR operation. These blocks are combined with the device key to generate the final 16-byte MAC (Message Authentication Code), i.e., the target message authentication code. The XOR operation is a bitwise operation with the following rules: if the values ​​of two corresponding bits are the same, the result is 0; if the values ​​of two corresponding bits are different, the result is 1. The XOR operation is exclusive, meaning that two events cannot be true simultaneously, emphasizing a "mutually exclusive" relationship. Finally, the target message authentication code is hashed to obtain a 2-byte anti-counterfeiting field.

[0071] Due to the efficiency and security of the AES-CMAC algorithm, using the AES-CMAC algorithm to calculate the anti-forgery field can make the anti-forgery of broadcast messages more efficient and secure. S130, broadcast messages are sent via Bluetooth.

[0072] In this embodiment, after receiving the broadcast message, the Bluetooth sensor can send the broadcast message to the vehicle's infotainment system via Bluetooth broadcast.

[0073] Preferably, the Bluetooth sensor can send broadcast messages via BLE broadcast. BLE (Bluetooth Low Energy) broadcast is a mechanism used by BLE devices to periodically announce their presence. Bluetooth Low Energy (BLE), also known as Bluetooth Low Energy, is a personal area network (PAN) technology designed and marketed by the Bluetooth SIG. Compared to classic Bluetooth, BLE aims to significantly reduce power consumption and cost while maintaining the same communication range.

[0074] The wireless communication method provided in this invention can be applied to a Bluetooth sensor. First, in response to a sensor trigger event, it acquires service information and a device key. Then, it generates a broadcast message with a predefined format based on the device key and service information. The broadcast message includes an anti-counterfeiting field. Finally, it sends the broadcast message via Bluetooth broadcast, allowing the vehicle's infotainment system to receive and parse it. This wireless communication method, by employing Bluetooth broadcast for communication between the Bluetooth sensor and the vehicle's infotainment system, is not limited by the number of connected devices and reduces device power consumption. Furthermore, by adding an anti-counterfeiting field to the broadcast message, it prevents unauthenticated devices from forging the broadcast, thus protecting information security.

[0075] Example 2

[0076] Figure 4 This is a flowchart of a wireless communication method provided in Embodiment 2 of the present invention. This embodiment is applicable to situations where a vehicle-mounted system communicates wirelessly with external devices. The method can be executed by the vehicle-mounted system, which can be implemented in hardware and / or software and configured in a vehicle. Figure 4 As shown, the method includes:

[0077] S210: Scan for external broadcasts and receive broadcast messages sent by the Bluetooth sensor.

[0078] The broadcast message includes a first message field and an anti-counterfeiting field.

[0079] In this embodiment, the vehicle's infotainment system can continuously scan for external broadcasts to receive broadcast messages sent by the Bluetooth sensor.

[0080] Optionally, the anti-counterfeiting field can be generated by: combining the first message field with the device key and combining it with a block encryption algorithm to obtain the target message authentication code; and hashing the target message authentication code to obtain the anti-counterfeiting field.

[0081] Specifically, the broadcast message consists of a first message field and an anti-forgery field. The first message field contains business information, while the anti-forgery field is a signature field used to prevent the broadcast message from being forged. The anti-forgery field can be generated using block cipher algorithms such as AES-CMAC. First, the first message field is divided into blocks, each 128 bits (16 bytes). If the length of the first message field is not a multiple of 128 bits, it is padded with 0s; if the message length is already a multiple of 128 bits, no padding is performed. After block division, each block is encrypted using AES and iteratively processed using an XOR operation. These blocks are combined with the device key to generate the final 16-byte MAC (Message Authentication Code). Finally, the 16-byte MAC is hashed to obtain the 2-byte anti-forgery field.

[0082] By using device keys to generate anti-counterfeiting fields, it is possible to prevent unauthorized devices from forging broadcast messages, thereby improving the security of communication between the vehicle's infotainment system and Bluetooth sensors.

[0083] S220. Parse the anti-counterfeiting field to obtain the device key, and perform legality authentication on the broadcast message based on the device key. If the authentication is successful, parse the first message field to obtain the business information.

[0084] The key list contains device keys corresponding to each external device bound to the vehicle's infotainment system.

[0085] In this embodiment, the method for authenticating the legitimacy of broadcast messages based on device keys may be: obtaining a key list; matching the device key with the device identification information in the key list; if the match is successful, the authentication is successful.

[0086] Specifically, after receiving a broadcast message from the Bluetooth sensor, the vehicle's infotainment system can first parse the anti-counterfeiting field in the broadcast message to obtain the device key. It then matches the parsed device key against a pre-stored key list. If the pre-stored key list contains a key that matches the parsed device key, the match is successful, indicating that the broadcast message was sent by a device bound to the vehicle's infotainment system. After a successful match, the first message field can be parsed to obtain the business information contained within.

[0087] Optionally, the key list also includes device identification information corresponding to each external device bound to the vehicle's infotainment system. This device identification information can be used to manage Bluetooth sensor devices. After parsing the first message field, the device identification information and service information can be obtained. Based on the device identification information, it can be determined which Bluetooth sensor the broadcast message originated from, and the device identification information and service information are sent to the service provider (service-related software or hardware in the vehicle) for further processing or execution.

[0088] Figure 5This is a schematic diagram illustrating communication between a Bluetooth sensor and a vehicle-mounted infotainment system according to an embodiment of the present invention. As shown in the figure, the Bluetooth sensor sends a broadcast message to the vehicle-mounted infotainment system via Bluetooth broadcast. The vehicle-mounted infotainment system receives the broadcast message sent by the Bluetooth sensor by scanning for external broadcasts. If the vehicle-mounted infotainment system can successfully parse the received broadcast message, it notifies other service providers of the parsed information for processing.

[0089] The wireless communication method provided in this invention can be applied to in-vehicle infotainment systems. First, it scans external broadcasts and receives broadcast messages sent by Bluetooth sensors. Then, it parses the anti-counterfeiting field to obtain the device key. The device key is then matched against a pre-stored key list. If a match is found, the first message field is parsed to obtain service information. This wireless communication method uses Bluetooth broadcasting for communication between the Bluetooth sensor and the in-vehicle infotainment system, which is not limited by the number of connected devices. Furthermore, because an anti-counterfeiting field is added to the broadcast message, it prevents unauthenticated devices from forging broadcasts, thus protecting information security.

[0093] The broadcast message generation module 320 is used to generate broadcast messages in a set format based on the device key and service information.

[0094] The broadcast message includes an anti-counterfeiting field.

[0095] The broadcast message sending module 330 is used to send broadcast messages via Bluetooth, so that the vehicle's infotainment system can receive and parse the broadcast messages.
