In one embodiment, as shown in fig. 2, a method for executing a program processing is provided, which is described by taking the method as an example applied to the server in fig. 1, and may include the following steps:
step S202, receiving an execution program uploaded by the provisioning terminal.
The execution program may be a script program in various application scenarios, for example, may be a credit generation program used in a credit generation algorithm, or may also be an application program used in some application software, and the like. Specifically, the executive program may be source code written by a plurality of different scripting languages, such as Shell language, Perl language, Python language, and the like, which is not limited in this application.
In practical application, a user may compile an execution program through a provisioning terminal, and upload the compiled and packaged execution program to a cloud server through a network, for example, upload the execution program to the cloud server in the form of a compressed file.
Specifically, the execution program written by the user through the provisioning terminal may be an execution program saved in a plurality of different files and named by different file names, for example, saved as "main. The compressed file uploaded to the server at the cloud end may be a compressed file obtained by compressing and packaging the plurality of files in a unified manner.
When the user uploads the compressed file to the cloud server through the supply terminal, the user can also fill in corresponding execution program information through the supply terminal, for example, information such as a relative path of files of each execution program, names of the files, a writing language, versions of the writing language, and operation parameters.
Step S204, splitting the execution program, generating a plurality of execution subroutines, and encrypting the plurality of execution subroutines respectively.
After receiving the compressed file uploaded by the supply terminal, the server at the cloud end can decompress the compressed file to obtain the execution programs stored by the plurality of files.
Further, the server at the cloud end can traverse all program statements of the executive programs stored in the files, split the program statements and encrypt the executive subprograms obtained by splitting the program statements. The encryption key may be an encryption key filled in by a user when the compressed file is uploaded through the demand terminal. The server in the cloud end can encrypt each execution subprogram according to the encryption key.
Specifically, the Encryption algorithm for encrypting each execution subroutine may be a symmetric Encryption algorithm, for example, an Advanced Encryption Standard Algorithm (AES), a data Encryption Standard algorithm (DES), a Triple data Encryption algorithm (Triple DES, 3DES), a Blowfish Encryption algorithm, or the like.
In practical application, the server in the cloud may write each encrypted execution subprogram into each new file and store the new file, where a file name of each stored encrypted execution subprogram is a Universal Unique Identifier (UUID) generated at random.
Step S206, a rule file associating the execution program and the encrypted execution subprogram is generated, and the rule file is encrypted.
The rule file is used to associate the execution program with the encrypted execution subprogram, and may store the file name and the storage address of the execution program, the file name of the encrypted execution subprogram, and the splitting order in which the execution program is split into the execution subprogram.
Specifically, the cloud server may generate a rule file associated with the execution subprogram and the encrypted execution subprogram according to the acquired relevant information of the execution program and the execution subprogram, and encrypt the rule file according to the aforementioned symmetric encryption algorithm.
Step S208, receiving a download request for the executive program sent by a demand terminal, and sending the encrypted executive subprogram and an encrypted rule file to the demand terminal according to the download request, wherein the rule file is used for indicating the demand terminal to recombine the executive subprogram to obtain the executive program.
The demand terminal may be a terminal device running the execution program, and may be, but is not limited to, a personal mobile phone, a notebook computer, a smart phone, a tablet computer, a portable wearable device, and a server or a server cluster.
Specifically, the demand terminal may send a download request for downloading the execution program to the server in the cloud in response to a request operation of the user. The download request may carry information such as a program name or a program ID of the executable program to be downloaded, and a version number of the executable program.
The server at the cloud end can authenticate the demand terminal according to the download request, and after the authentication is passed, the corresponding encrypted rule file and the encrypted execution subprogram are determined according to the program name or the program ID, the version number and the like carried by the download request, and the encrypted rule file and the encrypted execution subprogram are sent to the demand terminal.
Further, the demand terminal may decrypt and recombine the received encrypted rule file and the encrypted execution subprogram to obtain and run the execution program.
In practical application, the key for decryption by the demand terminal may be a key obtained by a user from a key provider online and entered through a human-computer interaction interface of the demand terminal, or may also be a key obtained by another application running in the demand terminal from the key provider. Wherein, the key supplier may be a user who fills out the encryption key through the demanding terminal.
In the execution program processing method, the received execution program is split and encrypted respectively to generate a plurality of encrypted execution sub programs, then a rule file associating the execution program and the encrypted execution sub programs is generated and encrypted, and when a download request for the execution program sent by a demand terminal is received, the encrypted execution sub programs and the encrypted rule file are sent to the demand terminal according to the download request, and the rule file is used for indicating the demand terminal to recombine the execution sub programs to obtain the execution program. Therefore, the program sent to the demand terminal is not an execution program subjected to simple encryption, but a plurality of execution sub-programs subjected to splitting and encryption, and the demand terminal can not simply decrypt the execution program for use, but recombines the execution sub-programs according to the rule file, so that the demand terminal cannot directly acquire the execution program, and the problem of confidentiality of the execution program is solved.
In one embodiment, the splitting of the execution program in step S204 may be performed according to a writing order of programs in the execution program and a requirement on the number of programs.
Specifically, after traversing the execution programs of the plurality of files, the server at the cloud splits each execution program into a plurality of execution subroutines according to the writing sequence of the programs in each file and the preset requirement for the number of the programs, for example, the server splits the execution program according to 4 lines of program statements, 5 lines of program statements, or any line of program statements as one execution subroutine, and then encrypts and stores the split execution subprogram in the encryption manner described above.
In other embodiments, the number of the execution subroutines to be generated may be preset, and then each execution program is traversed and split to obtain the preset number of execution subroutines.
Referring to fig. 3, fig. 3 is a schematic flow chart of a rule file generating step in an embodiment, where the rule file generating step is to generate a rule file associating the execution program and the encrypted execution subprogram, and specifically includes the following steps:
step S302, a file name and a storage location of the execution program are acquired.
The file names of the execution programs are the file names of the main, the domain, the analysis, the sh1, the domain, the analysis, the sh2 and the like, and the storage positions are positions where the cloud server decompresses and obtains the execution programs and stores the execution programs to the server database after receiving the compressed files uploaded by the supply terminal.
In practical application, the cloud server may obtain the file name of each execution program according to the execution program information entered by the user at the provisioning terminal, and obtain the storage location of each execution program according to the location where each execution program is stored in the database after decompression.
Step S304, obtaining the file name of the encrypted execution sub-program.
Specifically, after the execution program is split into the execution sub programs, the server in the cloud may write the encrypted execution sub programs into the new files and store the new files, and the file names of the stored encrypted execution sub programs are the randomly generated universal unique identification codes, such as "b 6b4f9-904a-86cc-9c6 fe" and "b 6b4f9-904a-4ec1-9c6 fe".
In practical application, when the server at the cloud generates the file name of the encrypted execution subprogram, the file name can be obtained.
Step S306, generating the rule file based on the file name and the storage location of the execution program, the splitting order of splitting the execution program, and the file name of the encrypted execution subprogram.
Specifically, when the server in the cloud performs splitting processing on the execution programs, the server in the cloud may further record a splitting order in which each execution program is split to obtain the execution subprogram, then split each execution program according to the obtained file name of each execution program, the relative storage location between each execution program, the splitting order in which each execution program is split to obtain the execution subprogram, and the stored file name of each encrypted execution subprogram, write the new rule file in, and then encrypt and store the new rule file.
By acquiring the file name and the storage position of each execution file, the splitting sequence for splitting each execution program and the file name of the encrypted execution subprogram, and generating the rule file, after the requirement terminal downloads and decrypts each execution subprogram, each execution subprogram can be recombined according to the instruction of the rule file, so that the execution file is obtained and operated.
As shown in fig. 4, in one embodiment, another method for executing a program is further provided, and the method is used for explaining the requirement terminal in fig. 1 as an example, and may include the following steps:
step S402, sending a download request of the execution program to the cloud.
Specifically, the demand terminal may send a download request to the server in the cloud in response to a request operation of the user. The download request may carry information such as a program name or a program ID of the executable program to be downloaded, and a version number of the executable program to be downloaded.
In practical application, the demand terminal may determine the version of the adapted execution program according to information such as its own system configuration, and determine the corresponding version number.
Step S404, receiving an encrypted execution subprogram corresponding to the download request and an encrypted rule file returned by the cloud, where the encrypted execution subprogram is obtained by splitting and encrypting the execution program, and the rule file is associated with the execution subprogram and the execution program.
Specifically, the server at the cloud end can send a download request according to the demand terminal, authenticate the demand terminal, determine a corresponding encrypted rule file and an encrypted execution subprogram according to a program name or a program ID, a version number and the like carried in the download request after the authentication is passed, and send the encrypted rule file and the encrypted execution subprogram to the demand terminal.
Step S406, decrypting the encrypted rule file and the encrypted execution subprogram to obtain the rule file and the execution subprogram.
The key for decryption may be a key obtained by a user from a key provider on line and entered through a human-computer interaction interface of the demand terminal, or may also be a key obtained by another application running on the demand terminal from the key provider.
Specifically, the demand terminal may encrypt the encrypted rule file and the encrypted execution subprogram according to the obtained key, so as to obtain the rule file and the execution subprogram.
And step S408, recombining the execution subprogram according to the rule file to obtain an execution program corresponding to the downloading request.
The demand terminal can recombine the decrypted execution subprogram according to the content written in the rule file to obtain the execution program corresponding to the download request.
The method comprises the steps of sending a download request to a cloud end, receiving an encrypted execution subprogram and an encrypted rule file which are returned from the cloud end and correspond to the download request, splitting and encrypting the execution subprogram, associating the execution subprogram with the execution subprogram, decrypting the encrypted rule file and the encrypted execution subprogram, and recombining the decrypted execution subprogram according to the decrypted rule file to obtain a corresponding execution program. The executive program obtained by the demand terminal is obtained by decrypting the encrypted rule file and the encrypted executive subprogram and recombining the executive subprogram based on the rule file, and is not the executive program obtained directly, so that the problem of confidentiality of the executive program is solved, and the confidentiality of the executive program is improved.
In one embodiment, referring to fig. 5, fig. 5 is a schematic flow chart of the step of executing program reorganization in an embodiment, where the step of executing program reorganization, that is, reorganizing the execution sub program according to the rule file in step S408 to obtain the execution program corresponding to the download request, may include the following steps:
step S502, according to the file name of the encrypted execution subprogram in the rule file, determining the corresponding execution subprogram.
Step S504, according to the splitting order of splitting the execution program in the rule file, reorganizing the determined execution subprogram, and generating a plurality of execution programs.
Specifically, after decrypting the encrypted execution subprogram, the demand terminal may sequentially obtain and recombine the decrypted execution subprograms according to the splitting order in which each execution program is split into the execution subprograms in the rule file and the file names of the generated execution subprograms, so as to obtain the multiple execution programs.
In step S506, the file names of the executed programs are obfuscated.
Specifically, the demand terminal may obfuscate a file name of each execution program, and the obfuscated file name of each execution program is a universal unique identifier generated at random. For example, the file names of the execution programs uploaded by the supply terminal are "main.sh", "domain analysis.sh1" and "domain analysis.sh2", and the file names of the execution programs obtained by the demand terminal after being confused are "b 6b4f9-904a-4ec1-86cc-9c5546 fe", "b 6b4f9-904a-4ec1-86cc-9c7846 fe", "b 6b4f9-906a-4ed1-86cc-9c5546 fe".
In step S508, the file names of the execution programs that refer to each other among the execution programs are modified to be the obfuscated file names of the execution programs.
Specifically, when each execution subprogram is a reorganized execution program, when the file name of the execution program written in a regular file in the reorganized execution program is identified, the file name is replaced with the corresponding file name after confusion, for example, a "doanalysis.sh1" field is detected in a program statement of the reorganized execution program, and the "doanalysis.sh1" in the regular file is the file name of the execution program, when the execution program is generated through reorganization, the demand terminal modifies the "doanalysis.sh1" in the reorganized execution program into the confused file name "b 6b4f 9-a-4 ec 1-904-86 cc-9c7846 fe", and saves the modified execution program.
In the above embodiment, the file names of the execution programs are obfuscated, and the file names of the execution programs that refer to each other in the reassembled execution programs are modified into the obfuscated file name of the execution program, so that the confidentiality of the execution program can be further improved.
In one embodiment, the method for executing program processing may further include: and after the executive program is operated, deleting the executive program.
Specifically, the execution program decrypted and recombined by the demand terminal may be a temporary execution program, and after the demand terminal runs the temporary execution program, the temporary execution program may be automatically deleted. For example, the corresponding temporary execution program may be deleted according to a corresponding deletion statement in the rule file, or the temporary execution program may be deleted after a certain period of time or after a certain number of times of operation according to a deletion field written in the temporary execution program.
After the execution program is operated by the demand terminal, the execution program is automatically deleted, so that the situation that the demand terminal stores the file of the execution program can be avoided, the execution program can be further kept secret, and the problem that the execution program cannot be kept secret is solved.
It should be understood that although the various steps in the flow charts of fig. 2-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
