[0045] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] Figure 1 This is one of the flow charts of the drone identity authentication method provided by an embodiment of the present invention.

[0047] like Figure 1 As shown, this embodiment provides a method for authenticating a drone identity, which can be executed by a ground control station of the drone. The method includes:

[0048] Step 101: receiving an authentication request data packet sent by a target UAV, wherein the authentication request data packet includes an identity of the target UAV and first timestamp information when the authentication request data packet is generated;

[0049] Among them, the authentication request data packet is generated by an encrypted hash algorithm. Specifically, the target drone can read its unique identifier, that is, the identity identifier, such as the serial number UAV-001, from its own memory, and obtain the timestamp information of the current moment from the internal real-time clock module, for example, it can be 2025-03-31 10:00:00. Then, the identity identifier and the timestamp information are spliced to obtain a character string. Still taking the above example, the obtained character string can be "UAV-0012025-03-31 10:00:00". Then, the SHA-256 algorithm can be called through the embedded encryption module to generate a 64-byte hash value, that is, to obtain the authentication request data packet.

[0050] After generating an authentication request data packet, the target drone can send the authentication request data packet to the ground station through a wireless communication unit, such as a 5G module. During this process, a lightweight protocol, such as the UDP protocol, can be used to reduce communication overhead.

[0051] Step 102: Parse the authentication request data packet to obtain the identity identifier and first timestamp information;

[0052] After receiving the authentication request data packet sent by the target UAV, the ground station can parse the authentication request data packet to obtain the identity identifier and the first timestamp information therein.

[0053] The ground station can also check the format and integrity of the first timestamp information to ensure security. If the timestamp information is found to be abnormal, the authentication request of the target drone can be directly rejected. The abnormal timestamp information may include the occurrence of future time, etc.

[0054] Step 103: Verify the identity through the blockchain network. If the identity verification passes, verify the first timestamp information.

[0055] In actual applications, the ground station can send the identity of the target drone to a nearby node of the target drone, namely the target node, through the blockchain network. The identity of the target drone and the first timestamp information can be verified in the target node.

[0056] Specifically, the verification of the identity through the blockchain network includes:

[0057] Comparing the identity with pre-stored registration records;

[0058] If the identity identifier is consistent with the registration record, it is determined that the identity identifier verification is successful.

[0059] The registration record can be generated in advance for the target drone when it is registered at the ground station. The purpose of the registration record is to verify whether the authentication request data packet sent by the target drone is consistent with the registration record. If they are inconsistent, it means that there may be a security issue with the target drone.

[0060] During implementation, when verifying the identity, the registration record, that is, the blockchain ledger, can be traversed to find the content that matches the hash value corresponding to the identity. If the corresponding hash value is found, it means that the target drone has been pre-registered, which means that the identity verification has passed.

[0061] Figure 2 This is a schematic diagram of the data structure of the blockchain ledger provided by an embodiment of the present invention.

[0062] like Figure 2 As shown, the blockchain ledger used in this embodiment can be of lightweight design, including a block header and a block body, wherein the block header includes the block height (such as #100), the previous block hash (such as "0x12ab..."), and a timestamp;

[0063] The block body records transaction data, such as {“id”:“HASH_UAV001”, “time”:“2025-03-31 10:05:00”, “action”:“register”}.

[0064] The verifying the first timestamp information includes:

[0065] Calculating a difference between the first timestamp information and the second timestamp information;

[0066] If the difference is within a preset standard time period, it is determined that the first timestamp information verification has passed.

[0067] In implementation, if |request time - registration time| ≤ 300 seconds (5 minutes), it can be determined that the first timestamp information verification has passed.

[0068] If the identity of the target drone is not found in the registration record, or the first timestamp information verification fails, it means that the received authentication request data packet may be illegal, and the verification information of "illegal identity" can be returned. The above verification process takes only about 0.1 milliseconds, reflecting the efficiency of the solution of this application.

[0069] Whether the above verification process is successful or failed, it can be recorded in the ground station for use in subsequent audits.

[0070] During the above step 103 , the target UAV does not need to perform any additional operations.

[0071] Step 104: Generate an identity authentication result and feed it back to the target drone.

[0072] In practical applications, the authentication result can be encapsulated into a response data packet and returned to the target drone through a wireless channel.

[0073] After the target UAV receives the identity authentication result, if the identity authentication is passed, a communication channel is established between the target UAV and a target node, where the target node includes a ground station and / or the UAV.

[0074] Specifically, the drone can initialize the communication key and negotiate the session key with the target node through the Diffie-Hellman protocol to establish an encrypted communication channel.

[0075] If the identity authentication fails, an exception record is generated and stored. At the same time, the communication attempt with the target node can be suspended, and the identity authentication request can be re-initiated after a set time.

[0076] In the drone identity authentication method provided in this embodiment, when the drone has a communication need, it can send an authentication request data packet to the ground station. The ground station can perform dual identity authentication on the drone through the identity identifier and timestamp information in the authentication request data packet to improve security. In addition, the above-mentioned identity authentication process is implemented using a blockchain network, which can also achieve decentralization and avoid single point failures.

[0077] In an exemplary embodiment, the blockchain network includes a plurality of nodes;

[0078] The authentication request data packet also includes trusted node information;

[0079] The verification of the identity through the blockchain network includes:

[0080] The identity is verified by a trusted node in the blockchain network.

[0081] Figure 3 This is the second flow chart of the drone identity authentication method provided by an embodiment of the present invention;

[0082] Figure 4 This is the third flow chart of the drone identity authentication method provided by an embodiment of the present invention;

[0083] The following combination Figure 3 and Figure 4 , describe the specific identity authentication process from the drone side and the ground station side respectively:

[0084] a) Generate the target drone’s identity hash value and register it to the blockchain network

[0085] Drone operation:

[0086] 1) After the drone is powered on, the internal microcontroller (e.g., ARM Cortex-M4) reads its unique identifier (e.g., serial number “UAV-001”) and obtains the current timestamp (e.g., “2025-03-31 10:00:00”) from the real-time clock (RTC) module.

[0087] 2) Concatenate the identifier and timestamp into a string (such as "UAV-0012025-03-31 10:00:00"), and use the embedded encryption module to call the SHA-256 algorithm to generate a 64-byte hash value (such as "HASH_UAV001").

[0088] 3) The drone sends the hash value and original timestamp to the ground control station via a wireless communication unit (such as a 5G module) to request registration. The format of the sent data packet is {"id":"HASH_UAV001","time":"2025-03-31 10:00:00","action":"register"}, with a total size of approximately 100 bytes.

[0089] Blockchain operation:

[0090] 1) After receiving the data packet, the ground control station verifies whether the timestamp is within a reasonable range (the difference from the current time is less than 1 minute) and confirms that the drone identity is not registered repeatedly.

[0091] 2) The ground station encapsulates the data packet into a transaction record in the format of {"id":"HASH_UAV001","time":"2025-03-3110:00:00","action":"register"}, with a fixed size of 200 bytes.

[0092] 3) The transaction record is broadcast to the blockchain network via the Internet. The master node (pre-set permission node) verifies the legitimacy of the transaction and writes it into a new block.

[0093] 4) Other nodes synchronize the new block through the P2P protocol to ensure ledger consistency. The block height is updated to #100, and the previous hash is linked to the previous block (e.g., "0x12ab...").

[0094] b) The drone sends an authentication request containing an identity and a timestamp

[0095] Drone operation:

[0096] 1) When the drone needs to establish communication with the target node (ground station or another drone), it reads the hash value "HASH_UAV001" from the memory during registration.

[0097] 2) Get the current timestamp (such as "2025-03-31 10:05:00") and concatenate it with the hash value to form an authentication request packet in the format of {"id":"HASH_UAV001","timestamp":"2025-03-31 10:05:00"}, which is approximately 80 bytes in size.

[0098] 3) Send data packets to the target node through wireless channels (5G or Wi-Fi), using lightweight protocols (such as UDP) to reduce communication overhead.

[0099] 4) The drone waits for the target node to respond with a timeout of 500 milliseconds. If there is no response, it will retry up to 3 times.

[0100] Blockchain operation:

[0101] 1) After receiving the authentication request, the target node parses the data packet and extracts the hash value and timestamp.

[0102] 2) Check the timestamp format and integrity to ensure it has not been tampered with. If the timestamp is abnormal (such as in the future), reject the request directly.

[0103] 3) Forward the request to the local node of the blockchain network and prepare to call the smart contract for verification.

[0104] c) The target node verifies the identity and the consistency of the ledger through the smart contract

[0105] Drone operation:

[0106] 1) The drone does not perform any direct operations in this step and only waits for the verification result of the target node.

[0107] 2) To improve efficiency, a list of recently verified nodes can be pre-stored on the drone side, and trusted nodes can be prioritized to initiate requests.

[0108] Blockchain operation:

[0109] 1) The target node calls the precompiled smart contract with the input parameters being the hash value “HASH_UAV001” and the timestamp “2025-03-31 10:05:00” in the request.

[0110] 2) The smart contract traverses the ledger (usually <10 transactions) and searches for a matching hash value. Once a record is found, the timestamp difference is compared: if |Request Time - Registration Time| ≤ 300 seconds (5 minutes), the transaction passes verification; otherwise, it is marked as invalid.

[0111] 3) If the hash value is not found in the ledger, an "illegal identity" error is returned. The verification process takes approximately 0.1 milliseconds, thanks to the lightweight ledger and pre-compilation optimizations.

[0112] 4) The verification result ("success" or "failure") is recorded in a temporary log to facilitate subsequent auditing.

[0113] d) Return the authentication result and establish a communication channel

[0114] Drone operation:

[0115] 1) The drone receives the result data packet returned by the target node (such as {"result":"success"}, about 20 bytes).

[0116] 2) If the result is "successful", the drone initializes the communication key (such as AES-128), negotiates the session key with the target node through the Diffie-Hellman protocol, and establishes an encrypted channel.

[0117] 3) If the result is "failed", the drone records the exception, suspends communication attempts with the node, and re-initiates the request after 1 minute.

[0118] Blockchain operation:

[0119] 1) The target node encapsulates the verification result into a response data packet and returns it to the drone through the wireless channel.

[0120] 2) If verification fails, the target node generates an abnormal transaction record (e.g., {“id”:“HASH_UAV001”, “time”:“2025-03-31 10:05:00”, “action”:“failed”}) and writes it to the blockchain for subsequent analysis.

[0121] 3) If the verification is successful, the target node and the drone complete the key negotiation, and the mission data can be transmitted after the communication channel is established.

[0122] It should be noted that the target node in the solution of this application can be a ground station or other drones. The following two specific embodiments illustrate two different situations of the drone identity authentication method provided by the solution of this application when the target nodes are different:

[0123] Example 1: Single UAV Authentication

[0124] Drone A (serial number "UAV-001") generates the hash "HASH_UAV001" and registers it to the ledger (height 100, 2025-03-31 10:00:00).

[0125] Drone A sends a request "HASH_UAV001+2025-03-31 10:05:00" to the ground station, which is verified successfully. It takes 0.11ms and the transaction size is 200 bytes.

[0126] Example 2: Multi-UAV Collaboration

[0127] Drones A, B, and C register "HASH_UAVA", etc. A requests authentication from B and a connection is successfully established.

[0128] Example 3: Complex environment testing

[0129] 5 drones, authenticated once per minute, 5 nodes, 0.15ms, 800 bytes of storage per node.

[0130] Technical details: Lightweight permission chain, transaction size <1KB, verification time <500ms.
