The server 104 may be implemented by a stand-alone server or a server cluster formed by a plurality of servers, and the provisioning terminal 102 and the demand terminal 106 may be, but are not limited to, a personal mobile phone, a notebook computer, a smart phone, a tablet computer, a portable wearable device, a server or a server cluster, etc.
In one embodiment, as shown in fig. 2, a method for executing a program is provided, which is illustrated by taking an example that the method is applied to the server in fig. 1, and may include the following steps:
step S202, receiving the execution program uploaded by the provisioning terminal.
The execution program may be a script program in various application scenarios, for example, a trusted program used in a trusted algorithm, or an application program used in some application software, etc. Specifically, the execution program may be source code written in a plurality of different scripting languages, such as Shell language, perl language, python language, etc., which is not limited in this application.
In practical application, a user may write an execution program through a provisioning terminal, and upload the written 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 or the like.
Specifically, the execution program written by the user through the provisioning terminal may be an execution program stored in a plurality of different files and named with different file names, for example, as "main.sh", "dornalysis.sh1", "dornalysis.sh2", or the like. The compressed file uploaded to the cloud server may be a compressed file obtained by uniformly compressing and packaging the plurality of files.
When the user uploads the compressed file to the cloud server through the provisioning terminal, corresponding executive program information, such as the relative path of the files of each executive program, the names of the files, the writing language version, the running parameters and the like, can be filled in through the provisioning terminal.
Step S204, splitting the execution program to generate a plurality of execution subroutines, and encrypting the execution subroutines respectively.
After receiving the compressed file uploaded by the provisioning terminal, the cloud server can decompress the compressed file to obtain execution programs stored in the files.
Further, the cloud server may traverse all program statements of the execution program stored in the plurality of files, split the program statements, and encrypt the split execution subprogram. The encryption key may be an encryption key that is filled in by the user when uploading the compressed file through the demand terminal. The cloud server may encrypt each execution subroutine according to the encryption key.
Specifically, the encryption algorithm used for encrypting each execution subroutine may be a symmetric encryption algorithm, for example, an advanced encryption standard algorithm (Advanced Encryption Standard, AES), a data encryption standard algorithm (Data Encryption Standard, DES), a Triple data encryption algorithm (Triple DES,3 DES), a Blowfish encryption algorithm, or the like.
In practical application, the cloud server may write each encrypted execution sub-program into each new file and store the encrypted execution sub-program, where the file name of each stored encrypted execution sub-program is a randomly generated universal unique identification code (Universally Unique Identifier, UUID).
Step S206, generating a rule file associated with the execution program and the encrypted execution subprogram, and encrypting the rule file.
The rule file is used for associating the execution program and the encrypted execution subprogram, and can store the file name, the storage address, the file name of the encrypted execution subprogram, the splitting order of splitting the execution program into the execution subprogram, and the like.
Specifically, the cloud server may generate a rule file associated with the execution sub-program and the encrypted execution sub-program according to the acquired execution program and related information of the execution sub-program, and encrypt the rule file according to the symmetric encryption algorithm described above.
Step S208, receiving a download request of the execution program sent by a demand terminal, and sending the encrypted execution 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 reorganize the execution subprogram to obtain the execution program.
The demand terminal may be a terminal device running the execution program, and may include, 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 respond to a request operation of the user and send a download request for downloading the execution program to a server in the cloud. The download request may carry information such as a program name or a program ID of the executable program to be downloaded, a version number of the executable program, and the like.
The cloud server can authenticate the demand terminal according to the downloading request, and after authentication, the corresponding encrypted rule file and encrypted execution subprogram are determined according to the program name or program ID, version number and the like carried by the downloading request, and the encrypted rule file and encrypted execution subprogram are sent to the demand terminal.
Further, the demand terminal may decrypt the received encrypted rule file and the encrypted execution subroutine, and reorganize the encrypted rule file and the encrypted execution subroutine to obtain and run the execution subroutine.
In practical applications, the key that the demand terminal decrypts may be a key that the user obtains from the key provider on line and enters through the man-machine interface of the demand terminal, or may be a key that is obtained from the key provider with other applications running on the demand terminal. Wherein the key provider may be a user who fills in the encryption key by requiring the terminal.
In the above execution program processing method, the received execution program is split and encrypted respectively to generate a plurality of encrypted execution subroutines, then a rule file associated with the execution program and the encrypted execution subroutines is generated and encrypted, when a download request for the execution program sent by the demand terminal is received, the encrypted execution subroutines and the encrypted rule file are sent to the demand terminal according to the download request, and the rule file is used for instructing the demand terminal to reorganize the execution subroutines to obtain the execution program. Therefore, the program sent to the demand terminal is not an execution program which is simply encrypted, but a plurality of split and encrypted execution subroutines, and the demand terminal can not simply decrypt the execution program for use, but reorganizes each execution subroutine according to the rule file, so that the demand terminal cannot directly acquire the execution program, and the confidentiality problem of the execution program is solved.
In one embodiment, the splitting of the executing program in step S204 may be performed according to the writing order of the programs in the executing program and the requirement on the number of programs.
Specifically, after traversing the execution programs of the files, the cloud server 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 on the number of the programs, for example, the server splits the execution program according to 4-stroke-sequence sentences or 5-stroke-sequence sentences or any row of program sentences as one execution subroutine, and then encrypts and stores the split execution subroutines according to the encryption mode described above.
In other embodiments, the number of execution subroutines to be generated may be preset, and then each execution program may be traversed and split to obtain the preset number of execution subroutines.
Referring to fig. 3, fig. 3 is a flowchart illustrating a rule file generating step in an embodiment, where the rule file generating step generates a rule file associated with the execution program and the encrypted execution subroutine, and specifically may include the following steps:
step S302, obtaining the file name and the storage location of the execution program.
The file names of the execution programs are the file names of main, doanalytical, sh1, doanalytical, sh2 and the like, and the storage position is the position of the server database in which the server in the cloud receives the compressed file uploaded by the supply terminal, decompresses the compressed file to obtain each execution program and stores each execution program.
In practical application, the cloud server can acquire the file name of each execution program according to the execution program information input by the user at the supply terminal, and acquire the storage position of each execution program according to the position of storing each execution program into the database after decompression.
Step S304, obtaining the file name of the encrypted execution subroutine.
Specifically, after splitting the execution program into execution subroutines, the cloud server may write each encrypted execution subroutine into each new file and store the encrypted execution subroutines, where the file names of each stored encrypted execution subroutine are randomly generated universal unique identifiers, for example, "b6b4f9-904a-86cc-9c6fe", "b6b4f9-904a-4ec1-9c6fe", and the like.
In practical application, when the cloud server generates the file name of the encrypted execution subroutine, the file name can be obtained.
Step S306, generating the rule file based on the file name, the storage location, the splitting order of splitting the execution program, and the file name of the encrypted execution subroutine.
Specifically, when the cloud server splits the execution program, the cloud server may record a splitting order of splitting each execution program to obtain an execution sub-program, then split each execution program to obtain a splitting order of the execution sub-program and a stored file name of each encrypted execution sub-program according to the obtained file names of each execution program and the relative storage positions among each execution program, write in a newly created rule file, and encrypt and store.
The method comprises the steps of obtaining the file name and the storage position of each execution file, splitting the splitting sequence of each execution program and the file name of each encrypted execution subprogram, and generating a rule file, so that after the terminal is required to download and decrypt each execution subprogram, each execution subprogram can be recombined according to the instruction of the rule file, and the execution file is obtained and operated.
As shown in fig. 4, in one embodiment, another method for executing a program is provided, which is used for illustrating the demand terminal in fig. 1 as an example, and may include the following steps:
step S402, a download request of the execution program is sent to the cloud.
Specifically, the demand terminal may send a download request to a 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 executing program to be downloaded, and a version number of the executing program to be downloaded.
In practical application, the demand terminal can determine the version of the adaptive execution program according to the information such as the own system configuration and the like, and determine the corresponding version number.
Step S404, receiving an encrypted execution subroutine and an encrypted rule file, which are returned by the cloud and correspond to the download request, where the encrypted execution subroutine is obtained by splitting and encrypting the execution program, and the rule file is associated with the execution subroutine and the execution program.
Specifically, the cloud server may send a download request according to the demand terminal, authenticate the demand terminal, determine the corresponding encrypted rule file and encrypted execution subroutine according to the program name or program ID and version number carried by the download request after authentication is passed, and send the encrypted rule file and encrypted execution subroutine to the demand terminal.
And 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 from a key provider by a user on line and entered through a man-machine interface of the demand terminal, or may be a key obtained from the key provider by other applications running on the demand terminal.
Specifically, the demand terminal may decrypt the encrypted rule file and the encrypted execution subroutine according to the obtained key, respectively, to obtain the rule file and the execution subroutine.
And step S408, reorganizing the execution subprogram according to the rule file to obtain an execution program corresponding to the downloading request.
The demand terminal can reorganize the decrypted execution subprogram according to the written content in the rule file to obtain the execution program corresponding to the downloading request.
The method comprises the steps of sending a downloading request to a cloud end, receiving an encrypted execution subprogram and an encrypted rule file, wherein the encrypted execution subprogram corresponds to the downloading request, the encrypted execution subprogram is obtained by splitting and encrypting the execution program, the rule file is obtained by associating the execution subprogram with the execution program, decrypting the encrypted rule file and the encrypted execution subprogram, and recombining the decrypted execution subprogram according to the decrypted rule file to obtain the corresponding execution program. The execution program obtained by the demand terminal is obtained by decrypting the encrypted rule file and the encrypted execution subprogram and recombining the execution subprogram based on the rule file, and is not the execution program obtained directly, so that the confidentiality problem of the execution program is solved, and the confidentiality of the execution program is improved.
In one embodiment, referring to fig. 5, fig. 5 is a flowchart illustrating an execution program reorganizing step in one embodiment, where in step S408, the execution sub-program is reorganized according to the rule file to obtain an execution program corresponding to the download request, and the method may include the following steps:
Step S502, determining the corresponding execution sub-program according to the file name of the encrypted execution sub-program in the rule file.
Step S504, reorganizing the determined execution subprogram according to the splitting order of splitting the execution program in the rule file, so as to generate a plurality of execution programs.
Specifically, after decrypting each encrypted execution sub-program, the demand terminal may split each execution program into a splitting order of the execution sub-program and a file name of the generated execution sub-program according to the rule file, and sequentially obtain and reorganize the decrypted execution sub-program to obtain the plurality of execution programs.
Step S506, obfuscating the file names of the execution programs.
Specifically, the demand terminal may confuse the file names of the execution programs, and the file names of the execution programs after confusion are randomly generated universal unique identification codes. For example, the file names of the execution programs uploaded by the supply terminal are "main.sh", "doanalysis.sh1", "doanalysis.sh2", and the file names of the execution programs obtained by the demand terminal after confusion are "b6b4f9-904a-4ec1-86cc-9c5546fe", "b6b4f9-904a-4ec1-86cc-9c7846fe", "b6b4f9-906a-4ed1-86cc-9c5546fe", and the like.
In step S508, the file names of the mutually referenced execution programs in the execution programs are modified as the file names of the confused execution programs.
Specifically, when the requirement terminal reorganizes each execution subprogram into an execution program, when the file name of the execution program written in a rule file in the reorganized execution program is identified, the file name is replaced by a corresponding file name after confusion, for example, a field of 'doanalysis.sh1' is detected in a program statement of the reorganized execution program, and 'doanalysis.sh1' in the rule file is the file name of the execution program, when the reorganized execution program is generated, the requirement terminal modifies 'doanalysis.sh1' in the reorganized execution program into a file name of 'b 6b4f9-904a-4ec1-86cc-9c7846 fe' after confusion, and stores the modified execution program.
In the above embodiment, by obfuscating the file names of the execution programs and modifying the file names of the execution programs that are mutually referenced in the reorganized execution programs to the file names of the obfuscated execution programs, confidentiality of the execution programs can be further improved.
In one embodiment, the illustrated execution program processing method may further include: and deleting the execution program after the execution program is operated.
Specifically, the execution program obtained by decryption and recombination by the demand terminal may be a temporary execution program, and after the demand terminal runs the temporary execution program, the demand terminal may automatically delete the temporary execution program. For example, the corresponding temporary execution program may be deleted according to the corresponding delete statement in the rule file, or the temporary execution program may be deleted after a certain period of time or a certain number of operations according to the delete field written in the temporary execution program, or the like.
After the demand terminal runs the execution program, the execution program is automatically deleted, so that the demand terminal can be prevented from storing the file of the execution program, the execution program can be further kept secret, and the problem that the execution program cannot be kept secret is solved.
