[0002] With the rapid development of unmanned mobile platform technology, it has played an indispensable role in many fields such as logistics distribution, agricultural plant protection, and environmental monitoring. They autonomously execute complex tasks, improving work efficiency and accuracy. While unmanned mobile platforms are becoming increasingly popular, the data security issue in their communication process has increasingly become a key factor restricting their further development.

[0003] Since unmanned mobile platforms usually need to transmit data in an open network environment, they face security threats from malicious programs; traditional communication encryption methods, although able to provide data protection to a certain extent, will seem inadequate in the face of increasingly complex attack means and there is a risk of being easily cracked or tampered with.

[0004] In response to the above problems, traditional communication encryption methods face security threats from malicious programs and there is a risk of being easily cracked or tampered with. Summary of the Invention

[0005] To solve the above problems, the present invention provides a communication encryption method for unmanned mobile platforms.

[0006] A communication encryption method for unmanned mobile platforms includes the following steps:

[0007] S1. Combining with a preset blockchain data layer, according to the non-tamperable feature of the blockchain, input the factory parameter information of the production unit of the unmanned mobile platform, the maintenance parameter information of the maintenance unit, and the review parameter information of the review department into the blockchain data layer;

[0008] S2. Combining with a preset communication encryption model, use a communication encryption algorithm to encrypt the communication content of the unmanned mobile platform;

[0009] S3. Combining with a preset intelligent recognition model, real-time monitor programs without security authentication, and record the transmission paths of programs without security authentication in the intelligent recognition model to avoid unauthorized decryption of encrypted communication content by programs without security authentication;

[0010] S4. Construct a status determination model, and calculate the corresponding status value in combination with information related to the unmanned mobile platform;

[0011] S5. Design three state threshold ranges, judge the relationship between the status value and the three state threshold ranges, and select a qualified operation mode, a warning and positioning mode, and a scrapping and disposal mode;

[0012] S6. Construct an information interaction medium to connect the data stored in the blockchain data layer and check which mode among the qualified operation mode, warning positioning mode, and scrapping and disposal mode the unmanned mobile platform belongs to.

[0013] A further solution of the present invention is to establish a blockchain data layer, including the following steps:

[0014] Combine the relevant data of the unmanned mobile platform in the historical records, collect the factory parameter information of the production unit of the unmanned mobile platform, the maintenance parameter information of the maintenance unit, and the review parameter information of the review department, construct a data set of identity parameters related to the unmanned mobile platform, and establish a blockchain data layer through the data set of identity parameters;

[0015] The factory parameter information includes the factory serial number, factory date, and program verification code of the unmanned mobile platform, ensuring that one unmanned mobile platform corresponds to a set of factory parameter information;

[0016] The maintenance parameter information includes the maintenance information of the unmanned mobile platform and the next maintenance time of the unmanned mobile platform. The maintenance unit adopts double authentication of strict identity verification and password authentication, and adopts the principle of minimum privilege to ensure the compliance of data access;

[0017] The review parameter information includes the authentication information of the unmanned mobile platform, and the review department adopts double authentication of strict identity verification and password authentication.

[0018] A further solution of the present invention is to establish a communication encryption model, including the following steps:

[0019] Combine the AES-256 algorithm to establish a communication encryption model, satisfying the following formula,

[0020] C = E(K, P)

[0021] Among them, C represents the encrypted data; E represents the AES-256 algorithm; K represents the key, the secret information used for encryption and decryption, with a length of 256 bits; P represents the plaintext, that is, the original data to be encrypted;

[0022] In the encryption process of the AES-256 algorithm, the plaintext P is divided into multiple 128-bit groups, and each group is encrypted independently; the encryption process of the AES-256 algorithm includes 14 rounds, and each round requires four operations of byte substitution, row shift, column mixing, and round key addition.

[0023] A further solution of the present invention, step S2, includes the following steps:

[0024] The unmanned mobile platform negotiates the AES key with the control center. The unmanned mobile platform sends sensitive data towards the control center. The unmanned mobile platform uses the AES-256 algorithm and the negotiated AES key to encrypt the sensitive data, generating a complete ciphertext. The unmanned mobile platform sends the complete ciphertext to the control center via wireless communication. The control center receives the ciphertext and decrypts the ciphertext using the same AES-256 algorithm and the negotiated AES key.

[0025] A further solution of the present invention is to establish an intelligent recognition model, including the following steps:

[0030] A further solution of the present invention is to construct a status determination model, including the following steps:

[0031] Calculate the corresponding status value, satisfying the following formula,

[0032]

[0033] Among them, A represents the evaluation level, a value between 0 and 1, reflecting the performance level of the unmanned mobile platform at the current inspection point. The review department uses the communication accuracy, communication module response speed, and the danger coefficient of unsecurely authenticated programs to evaluate the level;

[0034] V represents the cumulative repair time of the communication module; T maxrepresents the maximum repair time threshold of the preset communication module, and the maximum repair time threshold is set according to the expected lifespan of the device, industry standards, and specific requirements; w1 and w2 represent weight coefficients, and w1 + w2 = 1;

[0035] Calculate the relative value of the repair time of the communication module. When V is close to or equal to T max At this time, the relative value approaching 0 indicates that the reliability of the communication module is very low.

[0036] A further solution of the present invention, step S5, includes the following steps:

[0037] Combine the state determination model of the unmanned mobile platform to calculate the corresponding state value, and set the first state threshold and the second state threshold;

[0038] If the state value is less than or equal to the first state threshold, select the scrapping processing mode; if the state value is greater than the first state threshold and less than or equal to the second state threshold, select the warning and positioning mode; if the state value is greater than the second state threshold, select the qualified operation mode.

[0039] A further solution of the present invention, step S5, further includes the following steps:

[0040] Select the scrapping processing mode. The unmanned mobile platform is internally equipped with GPS positioning communication, and transmits the GPS positioning of the unmanned mobile platform to the maintenance unit, informing the maintenance unit to give priority to arranging personnel for emergency measurement and repair, and the unmanned mobile platform is forcibly powered off and shut down;

[0041] Select the warning and positioning mode. The unmanned mobile platform transmits the GPS positioning of the unmanned mobile platform to the maintenance unit, and the maintenance unit and the merchant negotiate the repair time and go to the site for measurement and repair;

[0042] Select the qualified operation mode, which means that the performance of the unmanned mobile platform is stable, the measurement is accurate, and no additional repair or inspection is required; the unmanned mobile platform can be used normally, and users can rest assured to perform various communication transmissions.

[0043] A further solution of the present invention, step S6, includes the following steps:

[0044] According to the established blockchain data layer, design the corresponding information interaction medium. The public and consumers can view the relevant data recorded in the blockchain data layer through their mobile phones to check whether the unmanned mobile platform belongs to an illegal decryption program;

[0045] The general public and consumers, in combination with the corresponding information interaction medium, can check which mode the unmanned mobile platform belongs to among the qualified operation mode, warning positioning mode, and scrapping and disposal mode. At the same time, they can check whether there are potential unsecure authentication procedures and whether the unsecure authentication procedures belong to illegal procedures. The information interaction medium is provided with an appeal channel.

[0046] In summary, the present invention includes the following beneficial technical effects:

[0047] 1. This method combines the blockchain data layer and utilizes the immutable feature of the blockchain to input the factory parameter information, maintenance parameter information, and review parameter information of the unmanned mobile platform into the blockchain data layer, ensuring the security and integrity of this information during storage and transmission and preventing malicious tampering or forgery.

[0048] 2.

[0086] Exemplarily, assume an unmanned mobile platform that has been used for 2 years. Due to various failures or maintenance requirements during the 2-year use of the unmanned mobile platform, the cumulative maintenance time V of the communication module of the unmanned mobile platform is 50 hours;
