In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.
In the present embodiment, a file processing method is provided, and fig. 1 is a flowchart of a file processing method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring initial file information of an initial file, wherein the initial file information comprises a plurality of lines of information;
in this embodiment, the initial file generally refers to (but is not limited to) a configuration file that is stored in a specific way and needs to be called for starting the relevant application program, and accordingly, the initial file information may be (but is not limited to) information included in the configuration file that needs to be called for starting the relevant application program, such as a file location, a code instruction, an object program code, and the like; the method for obtaining the initial file may (but is not limited to) obtain the initial file by scanning all files in a specific path, may also be directly called from a specified path according to path information received in advance, may also be obtained by manual calling or input, and may also be obtained by other methods; the transmission of the configuration file may be performed through an internal line, or may be performed through a wireless network such as bluetooth, 3G/4G/5G/quantum communication network, and the like.
It should be noted that, because different applications execute different functions, configuration files required by different applications are different, that is, a configuration file to be called by one application may be single or multiple, and the content included in each configuration file may be multi-line information or single-line information; identifying a configuration file under a particular path may be, but is not limited to being, automatically identified when an application is launched.
Step S204, executing target processing on the initial file information line by line, wherein the target processing comprises the following steps: performing a first detection on initial file information in a current line; under the condition that the first detection result is that the initial file information in the current line contains target information, performing encryption processing on the target information to obtain target encryption information; replacing the target information with target encryption information to obtain target file information; writing the target file information into a position corresponding to the current line in the first file;
in the embodiment, as the target processing is performed on the initial file information line by line, omission caused by scanning errors can be avoided, so that the integrity of the processed initial file information is ensured; and the target encryption information obtained by encryption is written into the first file and directly replaces the target information with the target encryption information, so that a plaintext corresponding to the target encryption information does not need to be written into the first file, the encryption information leakage caused by reading the plaintext in the program starting process is avoided, and the safety of the file information is improved.
The line-by-line execution mode may be that the number of lines where the corresponding initial file information is located is judged by identifying the identification information included in the initial file information of each line, the number of lines where the corresponding initial file information is located is determined by counting the number of lines, or the number of lines where the initial file information is located is determined by other modes; the first detection may be to scan initial file information, and determine whether target information is included according to a scanning result, where the target information may be initial file information with a specific identifier, for example, in the initial file information including "WENC (1233)", "WENC (1233)" is the target information, "1233" is the initial file information to be encrypted, "WENC ()" is the identifier information for performing the identifier, and "ENC (1233)" is the target encryption information after performing the encryption processing; the encryption process may be to encrypt the aforementioned target information by a specific encryption algorithm, for example, but not limited to, it may be implemented by the cryptographic asymmetric encryption/decryption algorithm SM2, or may be implemented by other encryption/decryption algorithms; after the target encryption information is obtained, the initial file information can be written into a first file, and the target encryption information is used for replacing the target information to obtain a first file which does not contain the initial file information; wherein the first file may be a folder or a file template under a specific path.
In step S206, when the target process is executed for each line of information included in the initial file information, the initial file is deleted, and the first file is set as the target file.
In this embodiment, in the case that target processing is performed on each line of information, deleting the initial file is to avoid erroneous execution caused by scanning and reading of the initial file when the application program is started, and to avoid leakage of the initial file information due to existence of the initial file.
The deletion of the initial file may be implemented on a computer executing an application program, and the deletion of the initial file may be performed by a module or a device having a Logic calculation function, such as a Central Processing Unit (CPU), an MCU (micro control Unit), an FPGA (Field Programmable Gate Array), a Programmable Logic Controller (PLC), or the like, configured on the computer itself, or may be a computing device or a module externally connected to the computer, such as a cloud computer; the execution of deleting the initial file may be triggered and executed after the computer receives a trigger instruction sent when the last line of information also executes the target process, may be triggered and executed when the computer receives a result that the last line of information also executes the target process, or may be triggered and executed in other manners.
Through the steps, the target encryption information obtained by encryption is written into the first file and directly replaces the target information with the target encryption information, so that a plaintext corresponding to the target encryption information does not need to be written into the first file, the encryption information leakage caused by reading the plaintext in the program starting process is avoided, the safety of file information is improved, the problem of low information processing safety is solved, and the information safety is improved.
The main body of the above steps may be a base station, a terminal, etc., but is not limited thereto.
In an optional embodiment, the target processing further comprises:
step S2042, if the first detection result is that the target information is not included in the initial file information in the current line, writing the initial file information in the current line into a corresponding position of the first file with respect to the current line.

step S20402, a first file is generated in a target path, where the target path is a path where the initial file is located.

step S2044, obtaining configuration information of target equipment, wherein the target equipment is equipment for operating a target file;
step S2046, according to the configuration information, performing encryption calculation on the target information to obtain target encryption information.
In this embodiment, since the hardware configurations of the target devices executing the application programs are not completely the same, the encryption information calculated according to the configurations of the target devices is also not completely the same, so that the independence of the encryption information is ensured, and the leakage of the information is avoided.
The target device may be a server where the application program is located, a hardware device such as a CPU, and correspondingly, the configuration information may be (but is not limited to) information such as a network card MAC address, a CPU model, a CPU core number, and a pre-built 256-bit character string of the server where the application program is located; the encryption calculation mode can be realized by adopting a cryptographic asymmetric encryption and decryption algorithm SM 2.
In an optional embodiment, performing the encryption calculation on the target information according to the configuration information includes:
step S20462, performing superposition calculation on the configuration information to obtain an encrypted abstract;
step S20464, generating an encryption key according to the encrypted digest, wherein the encryption key comprises the encrypted digest;
step S20466, performing encryption calculation on the target information according to the encryption key to obtain target encryption information.
In this embodiment, the cryptographic digest may be (but is not limited to) calculated by superimposing the network card MAC address, the CPU model, the CPU core number, and the like of the target device on a built-in 256-bit character string, or may be calculated by other methods.
In an alternative embodiment of the method according to the invention,
before performing object processing on the initial file information line by line, the method further includes:
step S20404, performing first identification processing on information to be encrypted in the initial file information to obtain target information containing a first target identification;
in this embodiment, the identification of the information to be encrypted is to enable quick identification in the scanning process; wherein the first target identification may be (but is not limited to) the aforementioned "WENC ()"; the execution of the first identification processing may be (but is not limited to) implemented by a module or device with a logic computing function, such as a CPU, an MCU, an FPGA, and a PLC, configured by the computer itself, or implemented by a computing device or module external to the computer, such as a cloud computer.
Performing encryption processing on the target information to obtain target encryption information includes:
step S20468, performing encryption processing on information other than the first target identifier included in the target information to obtain target encrypted information;
in the present embodiment, the information other than the first target identification may be (but is not limited to) the aforementioned "1233".
Writing the target file information into the position corresponding to the current line in the first file comprises:
step S2062, replacing the first target identification included in the target file information with a second target identification to obtain updated target file information;
step S2064, writing the updated target file information as target file information into the position corresponding to the current line in the first file.
In the present embodiment, replacing the first target identification with the second target identification may be replacing the aforementioned "WENC ()" with "ENC ()".

When the application is started, the target device automatically identifies all the configuration file paths (corresponding to the step S202); then, scanning all the configuration files under the paths line by line (corresponding to the aforementioned step S204); if the security-sensitive information to be encrypted is found, a key pair is generated using a built-in key generation algorithm, and the original value is encrypted using the key and written back to the configuration file to overwrite the original value (corresponding to the target process in step S204 described above).
When the application is initialized, the ciphertext is decrypted by using the same key to obtain a plaintext value, and the initialization is only executed in the process of starting the application for the first time.
The generation of the key pair can be realized by adopting a state-secret asymmetric encryption and decryption algorithm SM2, the key pair adopted in the encryption and decryption process of the algorithm is generated by calculation based on a specific seed, and the seed generation adopts some hardware information of a server where an application program is located, such as a network card MAC address, a CPU model, a CPU core number and the like, and a pre-built character string with the length of 256 bits; in the calculation process, after the opinion information and the character string are overlapped, calculating an abstract, and determining a seed according to the abstract; because hardware information of different servers is different, key pairs of different servers are different, and ciphertexts of different servers after encrypting the same configuration value are also different.

firstly, generating a temporary file under the same directory of an original file, wherein the name of the temporary file is 'original file name. tmp';
then scanning the original file line by line;
if the line has no content to be encrypted, the encrypted ciphertext is written into the temporary file in the original mode, otherwise, the encrypted ciphertext replaces the plaintext and is written back into the temporary file;
after the original file is scanned and the temporary file is completely written successfully, the original file is deleted, the temporary file is renamed to the original file name, and finally the replacement of the configuration file is completed.
