[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] This case provides a method for registering car networking card information, see Figure 1 , is a flow chart of a method for registering Internet of Vehicles card information provided by an embodiment of the present invention, the method comprising:

[0060] Step S1, encrypting the collected link data registered by the Internet of Vehicles card to obtain an encrypted string;

[0061] Step S2, splitting the encrypted string to obtain several groups of data;

[0062] Step S3, filling the plurality of groups of data into positions of different color blocks of the Rubik's Cube model according to predefined rules;

[0063] Step S4, scramble the data in the Rubik's Cube model using a preset scrambling formula and upload it to the blockchain.

[0064] During the specific implementation of this embodiment, the registered link data of the Internet of Vehicles card is collected, and the link data includes various types of information of the Internet of Vehicles card information.

[0065] It should be noted that the method of obtaining information when registering a vehicle networking card and the specific process of obtaining information are conventional existing technologies and will not be described in detail here.

[0066] After the link data is obtained, the link data is encoded and encrypted to obtain an encrypted string.

[0067] It should be noted that the encoding encryption technology used at this time can use a conventional encoding method to convert the original data into an encrypted string.

[0068] After obtaining the encrypted string, in order to store the data in the positions of different color blocks of the Rubik's Cube model, the encrypted string needs to be split into several groups of data corresponding to the Rubik's Cube model.

[0069] It should be noted that the number of split data groups is not greater than the number of color blocks of the Rubik's Cube model. In specific implementation, the number of split data groups is determined according to the order of different Rubik's Cube models.

[0070] The plurality of groups of data are filled into the positions of different color blocks of the Rubik's Cube model according to a predefined rule, and each group of data is stored correspondingly at the position of a color block of the Rubik's Cube model.

[0071] The data in the Rubik's Cube model is scrambled using a preset scrambling formula and uploaded to the blockchain. The data can have different encryption states when it is transmitted in each node on the blockchain. In this way, even on a public chain, it can better protect the privacy and sensitive information of users and ensure the security of user data.

[0072] In another embodiment of the present invention, the method specifically performs the following steps when collecting link data:

[0073] Different types of registration information are collected through different resource nodes, and the link data are integrated according to the different types of registration information.

[0074] Establish a real-name chain for Internet of Vehicles cards, and N resource nodes share and update link data;

[0075] When this embodiment is implemented, the relational database is decoupled and distributed on the chain to achieve the unification of the real-name registration result data of multi-node Internet of Vehicles cards. The double-node multiple interaction process is abandoned, and the card verification link is changed to automatic node attribution and claim, which improves the efficiency and success rate of real-name registration. The public verification system reduces the verification steps and shortens the real-name registration time.

[0076] In another embodiment provided by the present invention, the resource node is a resource node that is pre-registered through a contract and assigned a platformID;

[0077] Establish a smart contract access control system for real-name registration of Internet of Vehicles. The model consists of a registration contract and a multi-node access control contract. The smart contract code is compiled into a bytecode file by the Ethereum virtual machine, and then the bytecode file is deployed in the blockchain. The data generated by this operation cannot be tampered with, and distributed trusted access control of the blockchain system for real-name registration of Internet of Vehicles can be achieved. When multiple nodes enter this blockchain, they need to access the smart contract system to sign the smart registration contract and access control contract. After successful registration, the system automatically assigns the platformID.

[0078] The resource nodes include automobile enterprise system resource nodes, operator system resource nodes, public verification resource nodes and business management system resource nodes.

[0079] See also Figure 2 , is a schematic diagram of the principle of the registration information acquisition method provided by an embodiment of the present invention. Establish a real-name chain of Internet of Vehicles cards, and N resource nodes share and update the link data: automobile enterprise system resource nodes, operator system resource nodes, and business management system resource nodes. Each node collects data and encrypts it on the chain. When the data is transmitted at each node, the encryption state is adjusted, and the link data is expanded and shared.

[0080] It should be noted that when the business management system resource node is implemented specifically, that is, the system resource node of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology conducts relevant business management.

[0081] Smart contracts are used in real-name registration applications to define registration access, identity information, and business configuration data rules. By using smart contracts, these transactions can be automatically executed and the correctness and fairness of resource nodes can be ensured.

[0082] In another embodiment provided by the present invention, when the automobile enterprise system resource node, the operator system resource node, the public verification resource node and the business management system resource node specifically obtain registration data, the following steps are included:

[0083] During the vehicle assembly phase, the automaker's TSP platform collects the ICCID-VIN association relationship, obtains the 4-code information, and updates it to the chain synchronously at the automaker's system node, collecting basic vehicle information, including brand, model, color, etc. The automaker's system resource node collects the name, ID number, ID photo, face recognition image and other identity information collected by the hardware device, and the vehicle-card information is collected through the TSP platform. The corresponding relationship between VIN and ICCID is updated on the chain.

[0084] When the Internet of Vehicles card is opened, the operator obtains the business information of the Internet of Vehicles card, including account opening date, activation date, package subscription information, card status, etc. The operator system resource node updates the PlatformID associated with the operator's card, the card's province of origin, the card's business configuration data (package, card status, service channel activation, etc.), and the real-name result to the chain based on the initial information of the link.

[0085] The resource nodes of the business management system are supplemented with operator identification and vehicle manufacturer identification, and based on the self-built compliance calculation logic unit, the correlation between the real-name conclusion and the card business configuration information is determined and the compliance result is updated on the chain.

[0086] It should be noted that when the business management system resource node is implemented specifically, that is, the system resource node of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology conducts relevant business management.

[0087] During the vehicle sales phase, the DMS system collects the owner’s or company’s ID information and on-site bareheaded photos, and AI capabilities perform ID authentication and identity verification. After successful verification, this part of the personnel’s identity information is updated. At the public verification node, AI algorithms perform personal or company ID authentication, identity verification, one ID, ten IDs, etc., and update the verification results on the chain.

[0088] In another embodiment provided by the present invention, the process of encrypting the acquired link data specifically includes the following steps:

[0089] Then encrypt the collected data with base64;

[0090] Taking the regular three-order Rubik's Cube as an example for modeling, a two-digit number is used to represent the length of the added random number, and then the data is concatenated into an encrypted string of "random number length + original data".

[0091] Then the encrypted string is divided into 54 groups on average, and each group has the same length. If there are groups that do not meet the number, random numbers are used to supplement them. The number of supplementary random numbers is indicated in the random number length. The final number is "random number length + original data + random number".

[0092] In another embodiment of the present invention, the process of filling data in step S3 specifically includes the following steps:

[0093] See also Figure 3 , is a schematic diagram of the principle of the Rubik's Cube model encoding provided by an embodiment of the present invention. The six faces of the Rubik's Cube are respectively defined as U (up), D (down), F (front), B (back), L (left), and R (right), and different color blocks on different faces are encoded differently.

[0094] When it is necessary to explain, in this embodiment, the specific principle of Rubik's Cube encoding is explained by taking the Rubik's Cube of the third order as an example. In other embodiments, Rubik's Cubes of other orders may be used, and the specific principles and working processes are not repeated here.

[0095] Set the initial state of the Rubik's Cube model, and encode the positions of each face according to the order of the Rubik's Cube model;

[0096] The plurality of groups of data are filled into different positions according to the predefined rules.

[0097] Then use the regular three-order Rubik's Cube complete scrambling formula (step method) to scramble the data to be encrypted. The scrambling formula is: BL2B'U'DBUR'F2LB2D'LR2FRBLBL'FR'L'F2L'.

[0098] It should be noted that this embodiment provides a Rubik's Cube scrambling formula, and other scrambling formulas may be used in other embodiments.

[0099] It should be noted that the initial state can be set by the scrambling formula in the restored state through the Rubik's Cube model. After the initial scrambling, the positions of different faces with different color distributions are used as the initial positions. The default restored state can also be used as the initial state.

[0100] It should be noted that the predefined rules can be determined according to the encoding order and the order of several groups of data, in ascending order, in descending order, or other matching relationships, which will not be described in detail here.

[0101] The use of the Rubik's Cube scrambling formula can make the same sensitive information encrypted into different encrypted strings each time, but the decryption function can restore the original information when it is finally decrypted. When the data rolls on different nodes on the blockchain, the scrambling formula is called once to scramble the encrypted information.

[0102] In another embodiment provided by the present invention, before uploading the scrambled data to the blockchain, the method also includes a process of performing a credibility verification.

[0103] The N-node person-vehicle-card information, real-name result information, and safety and compliance information are put on and off the chain using the magic cube blind twister, and demand sharing is achieved using smart contract technology to achieve the goal of improving real-name efficiency, real-name process security, and ensuring the unification of multi-node result data. A credit system model is established to ensure data security and execution strength in each link.

[0104] That is, the credibility of the resource node that collects the link data is verified, and when the credibility verification passes, the scrambled data is uploaded to the blockchain.

[0105] The smart contract system monitors the reputation value of each node in real time. When the node triggers the smart contract condition and the reputation value verification fails, the blockchain will call the smart contract bytecode to run locally, and then save the running results in the blockchain ledger.

[0106] It should be noted that in this embodiment, only the reputation value verification process during the chain-up process is described. The reputation value can also be used for verification during the data off-chain process to supervise the rule execution and business security of each node of the real-name blockchain and improve security.

[0107] In another embodiment provided by the present invention, the credibility verification process specifically includes the following steps:

[0108] Acquire, from the blockchain, reputation data of each resource node that collects the link data;

[0109] It should be noted that when different resource node systems execute smart registration contracts, they evaluate the reputation of node objects and write the reputation data into the blockchain. During the process of nodes performing real-name registration services, the reputation system dynamically changes the reputation according to the evaluation system method. When conducting specific evaluations, the reputation data is obtained from the blockchain.

[0110] Calculate the reputation based on the reputation data of each node;

[0111] Determine the relationship between the node's reputation and the preset reputation threshold.

[0112] When the reputation is less than the preset reputation threshold, it is determined that the reputation check has failed and the blockchain upload channel is closed;

[0113] When the credibility is not less than the credibility threshold, it is determined that the credibility check is passed.

[0114] By building a reputation system for real-name registration of the Internet of Vehicles: Establish a reputation system based on blockchain to evaluate the reputation of each participant (such as car companies, operators, etc.). This reputation system is an important factor in determining resource allocation, and can also be used to prevent fraud and as a basis for full node supervision of car dealers, operators, car owners, etc.

[0115] In another embodiment of the present invention, the reputation

[0116] Among them, α is the data authenticity factor, β is the task execution factor, γ is the link security factor, α+β+γ=1

[0117] The data authenticity factor α is the real-name data uploaded by the resource node and the authenticity factor of the government and enterprise system, and its proportion in the credit evaluation system.

[0118] Task execution factor β 为资源 The transaction data generated by the node and the data uploaded (such as car company sales and real-name data, operator account opening data and real-name data) are factors in measuring task execution and account for a certain proportion in the credit evaluation system.

[0119] Link safety factor γ 为 The proportion of security attacks in link data transmission in the reputation evaluation system.

[0120] r i is the number of matches between the data uploaded by the i-th resource node and the database, d i The number of times the i-th resource node uploads data, s i is the transaction data actually generated by the i-th resource node, f is the number of attacks or errors detected by the blockchain from the i-th resource node, m is the custom scoring base, and n is the number of nodes.

[0121] In another embodiment provided by the present invention, the method further includes a blockchain data off-chain process, specifically performing the following steps:

[0122] When the Rubik's Cube is restored to the initial state (not necessarily all colors are in the initial state). According to the predetermined rules, take out the data in the Rubik's Cube, parse the length of the first two random numbers, and then delete the random numbers that need to be filled according to the length of the random numbers. Finally, use base64 encoding to restore the data to obtain the final decrypted data.

[0123] The blind twisting method of the Rubik's Cube is used for encryption and decryption. There is no need to transmit the key, and there is no risk of key hijacking. At the same time, we do not need to worry about the hostage knowing that we use the Rubik's Cube for encryption and decryption. Because the Rubik's Cube can change its state no matter how it is scrambled. We can prevent the risk of password cracking by controlling the order of the n-order Rubik's Cube, the length of the random number, the placement of the predefined data in the Rubik's Cube, and the initialization state of the Rubik's Cube for base64 decryption.

[0124] In another embodiment provided by the present invention, when restoring the Rubik's Cube, the state of the n-order Rubik's Cube can be determined by the following formula: We can set any state of the Rubik's Cube as the initialization state, and only the state matching this state can be correctly translated into plain text for subsequent decryption.

[0125] Even-order Rubik's Cube state formula:

[0126] Odd-order Rubik's Cube state formula:

[0127] As for bareheaded photos, since they take up a lot of storage space, IPFS, a distributed storage technology, is used to cut large files into many small pieces and store them in multiple servers, thus avoiding the possibility of file loss caused by single-machine failure. While IPFS is splitting and storing files, it will calculate a hash summary, upload the hash summary to the chain, and obtain the accurate hash value of the file, and then obtain the original file through IPFS.

[0128] Refer to Table 1. The edge blocks that need to be exchanged are moved to the UL and RL blocks. The following formula is used to make three exchanges between these three edge blocks. Then, three reverse steps are used to move them back to their original positions to complete an edge exchange. A new module that needs to be returned to its original position is exchanged on the edge block DF, and the above steps are repeated until the three exchanges are completed.

[0129] Table 1 Schematic diagram of edge block switching formula

[0130] Edge block formula: (DF-UL-UR)

[0132] When switching corner blocks, refer to Table 2, move the corner blocks that need to be exchanged to the UFL and URF blocks according to the encoding, use the following corner block formula to make three exchanges, and move them back to their original positions using the reverse steps of the previous move to complete a corner exchange. A new magic block that needs to be returned to the buffer block DBL is swapped in, and the above steps are repeated until the three exchanges are completed.

[0133] Table 2 Schematic diagram of corner block switching formula

[0134] Corner block formula: (DBL-UFL-URF)

[0135]

[0136] When switching, the parity of the code is considered.

[0137] Parity occurs when encoding edge blocks. To solve this problem, a URF block is encoded once more at the end of the edge block, and a URF block is also encoded once more at the end when encoding corner blocks. Then, parity processing L′1′y′ is performed.

[0138] When the color direction of the parity corner block is incorrect and there is only one corner block in position but with incorrect color direction, the corner block with incorrect color direction is re-encoded to exchange the DBL and the corner block to achieve the purpose of parity processing.

[0139] When the final corner block color direction is the same as the initial state, the corner block is correct, and there is no need to encode the URF block again. Instead, it is directly adjusted to the top layer and the PLL formula involving the edge is used to solve and restore it.
