[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0029] Embodiment 1 Embodiment 1 of the present invention introduces a data transmission encryption method.

[0030] This embodiment provides a data transmission encryption method, which aims to solve the security and stability problems of data transmission and improve the security and reliability of data encryption; combining the characteristics of a preset database and advanced random number generation technology, it realizes random encryption and secure transmission of data, providing a more secure and reliable protection for data storage and transmission.

[0031] like Figure 1 The data transmission encryption method shown includes the following steps: Acquire the data to be transmitted, and store the acquired data to be transmitted in a preset database; Randomly generate random storage pages and grid side lengths based on a preset database, and perform grid division of the random storage pages according to the grid side lengths; Extracting the coded data at the intersection of each grid diagonal after the random storage page is grid-divided, and using the extracted coded data as a data encryption key; The data to be transmitted is encrypted according to the obtained data encryption key, and the encrypted data is transmitted to realize data transmission encryption.

[0032] In order to achieve secure data transmission, this embodiment adopts Figure 2The architecture diagram shown includes a preset database storage medium for storing the data encoding to be transmitted, a grid division module for performing grid division on random pages of the preset database storage medium, a code extraction module for extracting data encryption keys, and a random number generation module for generating two random numbers.

[0033] As one or more implementation methods, the size of the data to be transmitted in the preset database storage medium is matched with the numbering interval of the random number generation unit, two random numbers are randomly generated using the matched random number generation unit, and the corresponding two random number generation units are searched through the numbering interval corresponding to the two random numbers; one of the random number generation units is randomly used to generate a random number, and the random number is a random storage page in the preset database storage medium, and the random number generated by the other random number generation unit is the side length of the grid required to be divided by the grid division module, and then the grid division is performed on the random storage page through the grid division module.

[0034] It should be noted that when used for the first time, the storage size of the data to be transmitted is used as a reference to search for the corresponding numbering interval, and the corresponding random number generation unit is searched according to the numbering interval, and two random numbers are generated by the random number generation unit at the same time, and the two corresponding random number generation units are searched according to the numbering interval to which the two random numbers belong, wherein the random number generated by one of the random number generation units is used to randomly search for a random storage page in the preset database storage medium, and the random number generated by the other random number generation unit is used to create the side length of the grid divided by the grid division module; In subsequent use, a random number is generated by one of the two random number generation units used last time, and the random number generation unit to which the numbering interval corresponding to the random number belongs is used to find a random storage page in the preset database storage medium, and the random number generated by the other random number generation unit is used to create the side length of the grid divided by the grid division module.

[0035] In this embodiment, in order to ensure the disorder of the numerical values ​​generated by the random number generation unit and prevent the key from being cracked, each random number generation unit needs to pass a series of statistical tests of the random number test suite provided by NIST (National Institute of Standards and Technology) to detect various potential defects in the random number sequence, and can check whether there is an obvious pattern or periodicity in the random number sequence through entropy rate test, sequence correlation test, etc., and can determine whether the entropy value of the generator is high enough by analyzing the block entropy rate of the random data stream. If the entropy value of the random number sequence generated by the random number generation unit is high enough, it means that the generated random number sequence is more disordered, and there is no obvious pattern and periodicity in the random number sequence, which means that the random number generation unit generates a high-quality sequence, the generated sequence is truly random, and the possibility of being cracked is reduced.

[0036] As one or more implementation modes, the specific process of meshing is as follows: (1) Use dynamic meshing software, including but not limited to GAMBIT, TGrid, and GeoMesh. Before using dynamic meshing software for meshing, the preset database storage medium must be disconnected from the network to ensure that these code pages are not easily accessed or tampered with by unauthorized persons; (2) importing the random storage code page in the preset database storage medium selected by the random number generation unit into the grid division module, and creating the grid edge length data generated by the random number generation unit in the grid division module, starting from a corner of the grid division module, and grid division of the searched storage code page with the created edge length; (3) When performing grid division, the grid is divided from one corner of the storage code page to the other three corners. When the grid is close to the other three corners, the grid division module deletes the grids that exceed the boundary of the storage code page and retains the remaining grids.

[0037] It should be noted that when performing grid division, since the side length of the grid is randomly generated, when the grid is gradually divided from one corner of the coding page to the other three corners, a situation will occur. When approaching the other three corners of the coding page, the remaining space is not enough to divide a complete grid. In this case, all grids that cannot be divided completely are directly deleted, and all other grids are retained. This step can also further increase the disorder of code generation. The grid division does not adopt the division method of evenly covering the coding page to prevent the key from being cracked, thereby further improving the encryption effect.

[0038] As one or more implementation modes, after the grid division is completed, a diagonal line is generated on each grid by a programming language, and the coded data of the intersection of the diagonal lines is extracted, the extracted code is used as a data encryption key, the data to be transmitted is encrypted, and the encrypted data is used for data transmission, thereby realizing data transmission encryption; specifically: (1) Calculate the path of the diagonal line of each grid using the Python programming language and determine the encoded data of the position of the diagonal intersection of each grid; (2) Traverse the intersections of the diagonals of all the divided grids, extract the coded information at the intersections, extract the coded information at the intersections of the diagonals of each grid, and use the hash function to rearrange the extracted codes. The rearranged codes are the encryption keys. (3) Encrypt the data to be transmitted using an encryption key and transmit the data through a unique interface. During transmission, use a secure communication protocol (such as TLS / SSL) to transmit the encrypted file to the target location to ensure the confidentiality and integrity of the data. At the target location of the data transmission, use the same encryption key and algorithm to decrypt the data. After decryption, verify the integrity of the data to ensure that the data has not been tampered with during transmission; (4) During data transmission, the system records key data such as the start time, end time, transmission speed, and recipient information for subsequent auditing and troubleshooting, so as to timely identify performance bottlenecks and optimize them.

[0039] It should be noted that in order to meet the real-time data transmission requirements, this embodiment uses a symmetric encryption algorithm to encrypt data, and formulates specific encryption strategies for different situations, such as data type, sensitivity level and transmission environment, including encryption algorithm selection, key management scheme, encryption granularity (field level, record level or database level), etc.

[0040] It should be noted that before extracting the key, this embodiment uses the previously selected symmetric encryption algorithm to encrypt the data to be transmitted. After the encryption is completed, the data will be transmitted to the target location through the unique interface and secure communication protocol set, and end-to-end encryption technology is used to ensure the security of the data during transmission. The data is automatically encrypted by the sender and encapsulated in data packets through TCP / IP, and then passed through the Internet as unreadable and unrecognizable data. When this information reaches the destination, it will be automatically reorganized and decrypted to become readable data, and in the whole process, access control technology is used to review and restrict user qualifications and permissions to prevent illegal users from accessing data or legal users from accessing data beyond their authority.

[0041] This embodiment generates random numbers through a random number generation module, which are used to select storage pages and grid side lengths, and then perform grid division and key extraction; the unpredictability of the encryption process is greatly enhanced, making the generation of encryption keys more difficult to crack, and improving data security. When used subsequently, a new random number is generated through one of the random number generation units used last time, so that each encryption process is based on the previous state, forming a dynamic and adaptive encryption mechanism; it can effectively resist potential cracking attempts, making data encryption more effective.

[0042] Embodiment 2 Embodiment 2 of the present invention introduces a data transmission encryption system.

[0043] like Figure 3 A data transmission encryption system shown includes: A data acquisition module, which is configured to acquire data to be transmitted and store the acquired data to be transmitted in a preset database; A grid division module, which is configured to randomly generate random storage pages and grid side lengths based on a preset database, and perform grid division of random storage pages according to the grid side lengths; A key extraction module is configured to extract the coded data at the intersection of each grid diagonal after the random storage page is gridded, and use the extracted coded data as a data encryption key; The encryption transmission module is configured to encrypt the data to be transmitted according to the obtained data encryption key, and perform data transmission on the encrypted data to realize data transmission encryption.

[0044] As one or more implementation modes, in the grid division module, before randomly generating random storage pages and grid side lengths based on a preset database, a random number generation unit matching the acquired data size to be transmitted is generated in the preset database, two random numbers are randomly generated based on the generated matching random number generation unit, and the corresponding two random number generation units are searched through the interval numbers corresponding to the two generated random numbers.

[0045] As one or more implementation methods, one of the obtained random numbers is used as a random storage page of a preset database, and another random number is used as a grid side length. Grid division is performed from one corner of the random storage page to the other three corners according to the obtained grid side length. When the division is close to the other three corners, the grids that exceed the boundary of the random storage page for grid division are deleted, and the remaining grids are retained to complete the grid division.

[0046] As one or more implementation modes, in the key extraction module, the intersections of the diagonals of all divided grids are traversed to extract the coding information at the intersections, the coding information at the intersections of the diagonals of each grid is extracted, and the extracted codes are rearranged using a hash function, and the rearranged coding data is the data encryption key.

[0047] As one or more implementation modes, in the encryption transmission module, the obtained data encryption key is used to encrypt the data to be transmitted, and a secure communication protocol is used to transmit the encrypted data information through a unique interface connected to a preset database, thereby realizing data transmission encryption based on the preset database.

[0048] As one or more implementation modes, before performing grid division of random storage pages, the preset database needs to be disconnected from the network to prevent the information from being accessed or tampered with without authorization.
