The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
The embodiment of the invention provides a file protection method which can be particularly applied to the protection process of a Unity3D program and a resource. As shown in fig. 1, the method in this embodiment includes the following steps:
step S101, encrypting each resource file to obtain each encrypted first resource file;
in this embodiment, the resource file may be specifically a file that can be displayed in a computer, such as a picture, an audio, a video, a text, a code, and the like. The encryption method for the resource file may adopt some existing encryption methods, such as the SHA1 algorithm.
Step S102, adding a shell to the executable file to obtain the executable file after adding the shell; the shell of the executable file after the shell is added is used for hijacking an operation function of a resource file, so that when the operation function of the resource file is called, a target first resource file is determined from the first resource files, the target first resource file is subjected to validity verification, and the target first resource file is decrypted under the condition that the target first resource file is verified to be legal.
In this embodiment, the operation of the resource file refers to a function related to the operation of the file, and the files corresponding to different platforms are different, for example, under windows, the functions mainly include CreateFile, OpenFile, setfilepointers, and CloseFile, that is, the operation function may specifically include one or more of the following: an open file operation function, a close file operation function, a read file operation function, and a write file operation function. For example, when the operation function for opening a file is called, it is necessary to determine a target first resource file from the first resource files, then further determine whether the target first resource file is legal, and decrypt the first resource file if the first resource file is legal.
In this embodiment, in order to verify whether the target first resource file is legal or not during decryption, it is necessary to add flag information to each encrypted first resource file. Judging whether the target first resource file contains mark information or not, and determining that the target first resource file is legal under the condition that the target first resource file contains the mark information; and under the condition that the target first resource file does not contain the mark information, determining that the target first resource file is illegal. The first resource file is judged whether to be legal or not by utilizing the mark information, if the first resource file contains the mark information, the first resource file is judged to be legal, and the first resource file needs to be decrypted; if the first resource file does not contain the mark information, the first resource file is illegal, and the first resource file does not need to be decrypted. Specifically, in this embodiment, whether the first resource file is valid may also be determined by judging whether the first resource file further includes flag information; for example, if the first resource file includes the flag information, it indicates that the first resource file is valid, and the first resource file may be opened, read, and written, and if the first resource file does not include the flag information, it indicates that the first resource file is invalid, and the first resource file does not need to be opened, read, and written.
In the embodiment, the resource file of the Unity3D program is encrypted, so that the resource file can be effectively protected, the problem that the resource file is stolen because the resource file is directly stored in a disk is solved, the security of the resource file is improved, and the security of the Unity3D program is further improved.
Another embodiment of the present invention provides a file protection method, and the method in this embodiment may be specifically applied to a process of decrypting a resource file. As shown in fig. 2, the present embodiment includes the following steps:
step S201, receiving operation of operating the executable file; the executable file is subjected to shell adding processing of a shell adding tool;
in this step, the executable file may be specifically a Unity3D program; the Unity3D program was previously shelled by a shelling tool. The operation may specifically include: single click, double click, etc. run the operation of Unity3D program.
Step S202, hijacking each operation function based on the shell of the executable file; the operation function is used for operating the resource file;
in this embodiment, when an executable file, that is, a Unity3D program is run, functions operated by the file may be hijacked by using the shell code, so that when the Unity3D program calls these functions, the functions may jump to the code in the shell, that is, the executable file is run in the shell, thereby hijacking and obtaining each operation function. Wherein, the operation function comprises one or more of the following: an open file operation function, a close file operation function, a read file operation function, and a write file operation function.
Step S203, when the target operation function is called, verifying whether the target first resource file to be operated is legal or not;
in this embodiment, the target operation function specifically refers to a currently called function in the hijack-obtained operation functions. For example, the operation functions obtained by hijacking include an open file function, a read file operation function and a write file operation function, and when the currently called file operation function is the open file function, the open file function is the target operation function.
In this step, verifying whether the target first resource file to be operated is legal specifically includes: judging whether the target first resource file contains mark information or not; determining that the target first resource file is legal under the condition that the target first resource file contains the mark information; and under the condition that the target first resource file does not contain the mark information, determining that the target first resource file is illegal. In this embodiment, before the executable file is run, the resource file is encrypted in advance to obtain the first resource file, and then the flag information is added to the tail of the first resource file, so that when the executable file is run and the encrypted first resource file needs to be referred to, whether the first resource file is legal or not can be determined according to whether the flag information is included in the first resource file, and the decryption operation is performed on the first resource file under the legal condition. In this embodiment, it may also be determined whether the first resource file is valid according to the flag information, so as to determine whether the format and the type of the first resource file are correct or determine whether the first resource file is tampered, and the resource file is opened, read, and written when the first resource file is determined to be valid.
Step S204, under the condition that the target first resource file is verified to be legal, the target first resource file is decrypted.
In this step, when the target first resource file is verified to be legal, the target first resource file may be decrypted by using a predetermined decryption method.
In the specific implementation process in this example, when the currently called function is the first operation function, that is, the operation function for opening the file, the location information of the target first resource file also needs to be obtained; and acquiring identification information of the first operation function; and establishing a first corresponding relation between the position information and the identification information, and storing the first corresponding relation, wherein the first corresponding relation can be stored in a handle table. When the operation function for opening the file is called, it is required to determine the first resource file to be operated as a target first resource file from the plurality of first resource files, that is, to determine which first resource file needs to be opened specifically, and then to determine the position information of the target first resource file, and at the same time to obtain the identification information of the operation function for opening the file; then, when the target first resource file is verified to be legal and needs to be decrypted, a first corresponding relationship between the position information of the target first resource file and the identification information of the operation function of the open file is established, and the first corresponding relationship is stored, and specifically, the first corresponding relationship may be stored in a handle table. Therefore, when a second file operation function is called subsequently, for example, when a file writing operation function or a file reading operation function is called, the storage position of the target first file can be determined according to the first corresponding relation stored in the handle table, then the target first resource file is obtained based on the target position, the obtained target first resource file is directly decrypted to obtain the resource file, the legality of the first resource file is not required to be verified, and the reading and writing efficiency of the resource file is improved.
In specific implementation of this embodiment, when the file reading operation function is called after the file opening operation function is called, the first resource file may be decrypted through the above steps to obtain a decrypted resource file, and then the decrypted resource file is stored in the cache location, and then the decrypted resource file is read from the cache location to the predetermined location. Similarly, when the file writing operation function is called after the file opening operation function is called, the first resource file can be decrypted through the steps to obtain a decrypted resource file, the decrypted resource file is stored in a cache position, and then the target content is written into the cache position to modify the resource file to obtain a modified resource file; encrypting the modified resource file to obtain a new first resource file; when the operation function for closing the file is called, the cache position can be released, and the target first resource file is closed. Specifically, after the modified resource is encrypted to obtain a new first resource file, mark information may be further added to the new first resource file, so as to provide a basis for subsequent validity verification of the first resource file.
In the embodiment, the operation function of the resource file is hijacked by using the shell of the executable file, so that when the resource file function is called to operate the target first resource, the decryption operation can be performed according to whether the target first resource file is legal or not. Because the target first resource file can be decrypted only when the executable file is operated, the resource file can be prevented from being stolen, the security of the resource file is improved, and meanwhile, the security of the executable file is greatly improved.
