[0020] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.
[0021] The present invention relates to the field of unmanned platforms. Focusing on the requirement of online short-distance concurrent filling of parameters of safety and confidentiality equipment of unmanned platforms in group collaboration scenarios, the data wireless distribution system architecture is constructed by using the Star Flash 2.0 technology to realize wireless, high-concurrency, high-reliability and high-security distribution guarantee from the safety and confidentiality management equipment of the central node of the unmanned platform group to the safety and confidentiality equipment of the end node.
[0022] This invention focuses on the needs of online dynamic and low-latency protection of secure and confidential data during collaboration of unmanned platform groups, and gives full play to the technical advantages of Star Flash 2.0 communication technology such as low latency, high throughput, high concurrency, high reliability, and anti-interference.

With high concurrency, high reliability, and high security wireless distribution capabilities of secure and confidential data, it supports the safe and flexible implementation of collaborative tasks of unmanned platform groups.
[0023] The present invention proposes a data wireless distribution method based on Star Flash 2.0 communication. Based on Star Flash 2.0 technology, a wireless distribution system architecture for secure and confidential data of unmanned platform group systems is constructed to achieve wireless, high-concurrency, and high-reliability distribution of secure and confidential data from the central node security and confidentiality management device of the unmanned platform group to the end node security and confidentiality device. Specifically, it includes:
[0024] 1. The communication architecture of the secure and confidential data assurance system based on Star Flash 2.0 communication has constructed a one-to-many system communication architecture with two types of nodes: security and confidentiality management equipment (as G nodes) and security and confidentiality equipment (as T nodes), and a wireless link architecture based on the Star Flash 2.0 communication protocol.
[0025] 2. The functional architecture of the security and confidentiality data assurance system based on Star Flash 2.0 communication inherits the access layer and basic service layer of the Star Flash 2.0 communication protocol, adds dedicated security and confidentiality assurance functions to the application layer, and then designs secure and confidential data flows to achieve high-security distribution of secure and confidential data.
[0026] 3. The wireless key distribution protocol based on Star Flash 2.0 communication adopts a dual security and confidentiality mechanism and designs the initial configuration, device discovery and pairing, authentication and authorization, establishment of communication links, transmission of dedicated key negotiation, data transmission, link maintenance, and disconnection of secure and confidential data wireless distribution to ensure interactive processes.
[0027] The present invention provides a data wireless distribution method based on Star Flash 2.0 communication. Based on Star Flash 2.0 technology, a wireless distribution system architecture for secure and confidential data of an unmanned platform group system is constructed to achieve wireless, high-concurrency, and high-reliability distribution of secure and confidential data from a central node security and confidentiality management device of an unmanned platform group to a terminal node security and confidentiality device.
[0028] 1. Communication architecture of secure and confidential data wireless distribution system based on Star Flash 2.0 communication
[0029] The security and confidentiality data protection system based on Star Flash 2.0 communication adds wireless communication terminals to security and confidentiality management devices and security and confidentiality devices, builds a wireless distribution link between the two types of devices, transmits security and confidentiality data, and realizes wireless distribution of security and confidentiality data.
[0030] The secure and confidential data protection system based on Star Flash 2.0 communication includes two types of nodes: security and confidentiality management equipment (as G nodes) and security and confidentiality equipment (as T nodes). The security and confidentiality management equipment and security and confidentiality equipment conduct one-to-many data security interaction through a wireless link based on the Star Flash 2.0 communication protocol. Figure 2 shown.
[0031] 2. Functional architecture design of secure and confidential data assurance system based on Star Flash 2.0 communication
[0032] The architecture diagram of the secure and confidential data assurance system based on Star Flash 2.0 communication consists of the access layer, basic service layer and application layer from bottom to top.
[0033] The access layer follows the access layer of the Star Flash communication system, which is composed of the Star Flash basic access technology SLB and the Star Flash low-power access technology SLE. The present invention mainly adopts the SLB access technology, which is responsible for the access and data transmission of the equipment;
[0034] The basic service layer follows the basic service layer of the Xingshan communication system, which consists of data transmission adaptation layer, device discovery, general management, service management, QOS management, security management and other functions, providing basic services involved in communication;
[0035] The application layer consists of two parts: one is the basic application of the Star Flash communication system, and the other is the dedicated security and confidentiality data protection related application, which completes the functions of security and confidentiality data distribution, basic configuration, equipment management, etc. Figure 3 shown.
[0036] 3. Secure and confidential data flow design
[0037] The above architecture determines the flow path of security and confidentiality data flow. On the security and confidentiality management device side, it flows from top to bottom in the order of application layer, basic service layer, and access layer. On the security and confidentiality device side, it flows from bottom to top in the order of access layer, basic service layer, and application layer. It is transmitted through the wireless communication channel in the middle, such as Figure 4 shown.
[0038] First, security and confidentiality data is generated at the application layer of the security and confidentiality management device, and the data is encapsulated and processed using a dedicated security and confidentiality protocol. The data enters the basic service layer, is encapsulated and processed using the service layer protocol, and is transmitted to the access layer. The data is encapsulated and processed according to the access layer protocol, and is transmitted to the security and confidentiality device through a wireless communication link for reverse processing.
[0039] 4. Design of wireless key distribution protocol based on Star Flash 2.0 communication
[0040] The wireless key distribution protocol based on Star Flash 2.0 communication includes: security and confidentiality management node (G node) and security and confidentiality device (T node). The two parties complete the secure parallel transmission of secure and confidential data through configuration, discovery, link establishment, negotiation, communication, and link breaking.
[0041] In terms of communication performance, based on the Star Flash technology evaluation, its parallel distribution capability, distribution rate, distribution delay, and block error rate are expected to be as follows:
[0042] (1) Parallel distribution capability: supports parallel distribution of 80 secure and confidential data within 1ms;
[0043] (2) Distribution rate: ≥450Mbps;
[0044] (3) Distribution delay: ≤30us;
[0045] (4) Block error rate: ≤1e-5.
[0046] In terms of security, a dual security and confidentiality mechanism is adopted, and a dedicated security and confidentiality protocol is added to the security and confidentiality protocol embedded in Star Flash Communication for end-to-end transmission protection of secure and confidential data to ensure the strong security of secure and confidential data. First, Star Flash Communication’s own security and confidentiality mechanism is used to encrypt and protect data transmission. It supports ZUC, SM4, and AES encryption algorithms, can authenticate access devices, and negotiate transmission encryption keys; second, a dedicated security and confidentiality mechanism is adopted, using dedicated algorithms and protocols to achieve encryption protection of secure and confidential data sources.
[0047] The specific process of wireless key distribution protocol interaction based on Star Flash 2.0 communication mainly includes: initial configuration, device discovery and pairing, authentication and authorization, establishing communication link, transmission private key negotiation, data transmission, link maintenance, disconnection, such as Figure 5 shown.
[0048] The specific process includes:
[0049] S1. Initial Configuration
[0050] The initial configuration includes two parts: configuring communication parameters and configuring basic security and confidentiality parameters.
[0051] Configuring communication parameters refers to configuring the basic parameters of Star Flash communication in the security and confidentiality management device and the security and confidentiality device respectively, including: connection management, measurement management, service management, security management and other parameters.
[0052] Configuring dedicated basic security and confidentiality parameters means configuring dedicated algorithm shared keys, shared parameters, etc. for security and confidentiality management devices and security and confidentiality devices respectively to ensure that both parties in communication can communicate securely.
[0053] S2. Device discovery and pairing
[0054] After the initial configuration is completed, the security and privacy management device and the security and privacy device will automatically scan the device. Once a pairable device is identified, it will first detect whether the device is a whitelist device. If it is a whitelist device, pairing will be performed. The detected device receives the pairing request and the two parties are paired successfully. Otherwise, the device will be ignored.
[0055] When multiple security devices are successfully paired with the security management device, they will be authenticated and authorized, establish communication links, etc. in a similar process until the connection is disconnected. Each connection will work independently in parallel.
[0056] S3, Authentication and Authorization
[0057] After the security and confidentiality management device and the security and confidentiality device are paired, two-way authentication is performed. Both parties use the preset shared key and other information in a non-interactive manner to authenticate using the Star Flash's own authentication protocol. If the authentication is successful, the transmission key negotiation is performed. Otherwise, the authentication fails and the operation is terminated. For nodes that have passed the authentication, both parties use the preset shared key to negotiate the transmission key negotiation and select the security and confidentiality mechanism to be executed based on the configuration information.
[0058] S5. Establish a communication link
[0059] Once authentication and authorization are completed, the security and confidentiality management device and the security and confidentiality device can start to establish a communication link, negotiate communication parameters (such as data rate, transmission power, etc.), and establish a stable connection for data transmission.
[0060] S6. Transmission private key negotiation
[0061] After the communication link is established, the security and confidentiality device actively initiates a negotiation request to the security and confidentiality management device. The security and confidentiality management device receives the request and uses the preset shared key and parameters to perform end-to-end encryption protection. Through secure interaction, both parties have the same key.
[0062] S7. Data transmission
[0063] After the dedicated security and confidentiality agreement is negotiated, the secure and confidential data can be transmitted. The transmission process is mainly as follows:
[0064] S71. The security and confidentiality management device generates security and confidentiality data and uses a dedicated security and confidentiality end-to-end encryption key to encrypt the data for protection;
[0065] S72. The dedicated security and confidentiality processing module of the security and confidentiality management device sends the encrypted data to the Star Flash processing module. The Star Flash processing module encrypts and protects the data, performs protocol encapsulation, and converts the data into a wireless signal after encoding and modulating it and sends it to the security and confidentiality device.
[0066] S73, the Star Flash module of the security and confidentiality device receives the wireless signal from the security and confidentiality management device, demodulates and decrypts it, parses the protocol, decrypts it, and sends the data to the dedicated security and confidentiality processing module of the security and confidentiality device, and the dedicated security and confidentiality processing module decrypts the data using the negotiated key, etc.;
[0067] S74. The security and confidentiality device stores the received data and feeds back the receiving result to the security and confidentiality management device.
[0068] S75. The security and confidentiality management device receives the feedback information and analyzes the feedback result. If the transmission is successful, it continues to send the next set of data. Otherwise, it decides whether to resend the data according to the configuration.
[0069] S76: This continues until all security and confidentiality data has been sent.
[0070] S8, Link Maintenance
[0071] During data transmission, the StarFlash module will continuously monitor the quality of the connection and make adjustments as needed to ensure the stability and reliability of the connection.
[0072] S9, disconnect the link
[0073] When the data transmission is completed, the security and confidentiality device will actively disconnect from the security and confidentiality management device. Or if an abnormality such as connection timeout occurs between the two parties, the connection will be disconnected.
[0074] The present invention proposes a data distribution method based on Star Flash 2.0 communication. Firstly, it gives full play to the advantages of low latency, high throughput, high concurrency, high reliability and anti-interference of Star Flash 2.0 communication technology, builds a secure and confidential data distribution system composed of security and confidentiality management equipment and security and confidentiality equipment, and designs and completes the secure and confidential data distribution protocol process, so that it can serve the protection of unmanned platform group collaboration; secondly, it adopts double security protection to enhance the security of the secure and confidential data wireless distribution system itself, so that it can be better applied to scenarios with high security requirements.
[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
