It is C code by the code conversion important in Java or in need for promoting safety, and is able to satisfy again normal
The demand of Java code parsing operation, then the safety that can will effectively promote Java code.
Fig. 1 is a kind of method flow diagram of herein described data processing method one embodiment.Although the application provides
As the following examples or method operating procedure shown in the drawings or apparatus structure, but based on conventional or without creative labor
Move in the method or device may include more or less operating procedure or modular unit.It is not present in logicality
In the step of necessary causality or structure, the execution sequence of these steps or the modular structure of device are not limited to the application implementation
Example description and execution shown in the drawings sequence or modular structure.The device in practice of the method or modular structure or end
It, can be according to embodiment or the connection carry out sequence execution or simultaneously of method shown in the drawings or modular structure when holding products application
Row executes (such as environment or even distributed processing environment of parallel processor or multiple threads).
Specifically as shown in Figure 1, a kind of data processing method that a kind of embodiment of the application provides may include walking as follows
It is rapid:
Step 101: obtaining target program packet, wherein the program code in target program packet is write by Java language
's；
I.e., it is possible to handle java applet packet, wherein the java applet packet can be being also possible to for Dex format
Jar format, wherein Dex format is applied in mobile terminal, and applying for Jar format either operates in clothes in windows system
It is engaged on device.The java applet packet of both formats can be carried out handling and convert.
When realizing, if it is desired to which conversion process is identical, then the program bag of Dex format can be turned
It is changed to the program bag of Jar format, is also possible to being converted to the program bag of Jar format into the program bag of Dex format, be also possible to not
The conversion for carrying out program bag format, can specifically select, the application is not construed as limiting this according to actual needs.By Jar format
Program bag when be converted to the program bag of Dex format, can be the dx that provides by android system for Jar format
Program bag is converted to the program bag of Dex format.
Above-mentioned acquisition target program packet can be the target program packet for obtaining user's input, be also possible to from database
The target program packet to be converted being stored in advance directly transferred.Specifically obtained using which kind of mode, it can be according to practical need
Selection is asked, the application is not construed as limiting this.
Step 102: said program code being filtered according to default filtering rule, obtains filtered program code；
In view of when carrying out code conversion, some codes are It is not necessary to be converted into C generation in java applet code
Code.For this purpose, can be filtered to program code, to filter out the Java code for not needing to carry out code conversion, for example, can
Filtering rule to be arranged in the following way:
1) initial method of class is filtered out；
2) filtering code that user specifies is filtered out；
3) method that JNI variable is generated in recursive call is filtered out.
The example of above-mentioned cited filtering rule is only a kind of exemplary description, can also be with when actually realizing
Filtering rule is set in other ways, for example, software developer only specifies a certain according to actual software security demand
The code of fraction needs to carry out the protection of more high safety, then it is to need to turn that software developer, which can specify only this partial code,
It is changed to C code, then filtering rule is exactly that all codes other than this partial code all filter out.
Specifically which kind of mode setting filtering rule using can set according to actual needs, and the application is not construed as limiting this.
Further, it is contemplated that the code for java applet packet itself (such as: Dex formatted file, Jar packet etc.) is all
Through overcompression, if the code conversion if being directly based upon java applet packet itself is C code, conversion process is relatively complicated,
The translation engine for needing to set is also relative complex.For this purpose, can the bytecode first to java applet packet itself parse, with life
At the intermediate file similar with smali format, the intermediate file of this format is not compressed, therefore, in after parsing
Between file to be converted to C language code more simple and convenient.
That is, being filtered according to default filtering rule to said program code, obtaining filtered program code be can wrap
It includes: the program code in target program packet being parsed, intermediate file is obtained；Intermediate file is filtered, is filtered
Program code afterwards.
Step 103: being C language code by the filtered program code translation.
Specifically, can be when by java applet code translation at C language code according to following translation rule
It is translated one by one:
1) for function name, function name can be translated according to JNI format, so that the function name after translation can pass through
Native code in Java calls directly；
2) for the variable in function, when translation, can find out in translation function the variable in need used,
And in the statement of the C function beginning of translation and defined variable；
3) it for the code in function, can translate one by one as follows until that has translated in function all patrols
Volume:
If it is logic judgment instruction or operational order (such as: if, goto, addition, position budget etc. instruction), can
To translate directly into corresponding C sentence；
If it is the code that needs are interacted with JVM, corresponding JNI function call can be translated into；
If encountering has abnormality processing in Java, label the and goto sentence that can use in C language is substituted.
That is, can be when being C language code by filtered program code translation by filtered program code
Middle logic judgment instruction and operational order, translate into corresponding C sentence；It will be needed in the filtered program code and JVM
Interactive code is translated as corresponding JNI function call, so that the code of some keys of java applet can be converted C
Language codes promote the safety of code, and the generation that wherein will need to interact with JVM so that cracking for calling program becomes trouble
Code, is translated as corresponding JNI function call, so that the JVM of understanding can be called by JNI interface, so that after translation
Java code can be performed.
It should be noted, however, that translation rule listed above is only a kind of illustrative rule, specific implementation
When, translation rule can also be adjusted, the application is not construed as limiting this in the case of different codes.
After translating into C language code, in order to avoid JVM is when executing, repeats, need to delete originally
The part code of C language code has been translated into JAVA code.That is, by the filtered program code translation at C
After language codes, code corresponding with the C language code in delete target program bag.Further, in order to enable JVM can
To call by JNI interface, can need to increase in Java code for having translated into the function name of the function of C language code
Add identification information, wherein identification information is translated into C language code for identifying the function, for example, can close by native
Key word is as identification information, that is, original Dex formatted file either Jar packet is modified, to having translated into C language code
Function adds native keyword, so that JVM when operation data packet, runs to the function, based on therein
Native keyword, which could be aware that, to be needed into the library function of C code to call the function.
For example, if in the program bag of script, the entitled public void foo of the function of foo function, if that will
For foo function translation for C language code, the function name of the foo function in script program bag is just adjusted to public native
void foo。
By filtered program code translation be C language code when, can according to but be not limited to according to such as lower section
Formula is translated:
1) function name in the filtered program code is translated according to JNI format；
2) variable that the function in the filtered program code needs to use is translated, and is stated at C function beginning
With the definition variable.
3) by logic judgment instruction and operational order in the filtered program code, corresponding C sentence is translated into；
4) code that will need to interact with JVM in the filtered program code is translated as corresponding JNI function tune
With.
It, can be according to specific for the content after translation after Java code is converted to C language code in the manner described above
Format generate C file, by the C file and change after Java file be combined, can be by having realized JNI interface
JVM runs these codes, to run program.
It is worth noting that, because of the system loading for being translated as Java code from C code reconvert when can promote operation, because
This, for java applet packet, which code needs to be translated as C phonetic code, which code does not need to be translated as C language generation
Code can be selected with system loading according to the actual needs, and the application is not construed as limiting this.
The above method is illustrated below with reference to a specific embodiment, it is important to note, however, that the specific implementation
Example does not constitute an undue limitation on the present application merely to the application is better described.
In this example, in order to increase the safety of code, the Java bytecode for being relatively easy to crack can be translated into C language
Then speech, then re-starts compiling and is packaged, so that the available effective guarantor of core logic or sensitive information in program
Shield.
Wherein, Java is the high-level language of an object-oriented, including the no characteristic of speech sounds of many C languages, such as: it is interior
Management is deposited, is inherited, heavy duty, interface, reflection etc..The application scenarios of Java are also relatively more abundant simultaneously, such as: server-side is moved
Moved end, IOT can be used.If realizing that Java to the switching between C language, will certainly just encounter procedural C language
Conflicting between Java characteristic abundant.In order to protect the stability and enhanced scalability of translation post code, can choose
Handle this imbalance using the JNI interface that Java is provided, wherein the operation of related to JVM (such as: Memory Allocation and
Recycling, interface calling etc.) JVM is all handed to by JNI to complete.
Based on the above analysis, the content interacted in code to be translated with JVM can all be entrusted into JNI, conversely, any
The JVM for realizing JM interface can run the C code after translation, be as shown in Figures 2 and 3 the processing block of the data processing method
Frame may include following translation flow:
S1: user inputs Dex formatted file or Jar packet；
S2: if the Jar packet of user's input, the dx that can be provided by Android, are converted to Dex format for Jar packet
File；
S3: parsing the bytecode of Dex file, to generate the similar intermediate file with smali format (in Fig. 3
IR), which is equivalent to the file after unziping it to Dex formatted file, which can make translation patrol
Collecting becomes simple.
S4: being filtered intermediate file by filter, to filter out the content for not needing translation, specifically, can be with
But it is not limited to be filtered according to logic below, that is, filter out following content:
* the initial method of class
* the static method of class
* the method for JNI variable is generated in recursive call
* user specifies the method to be filtered
S5: filtered content is exported to translation engine, is translated one by one by translation engine to specific instruction, and will translation
Content afterwards generates C file (that is, C file) by specific format；
S6: modifying to original Dex formatted file or Jar packet, specifically, can be to have translated into C language
Function add native keyword.
Above-mentioned translation engine can execute translation process according to logic as shown in Figure 4:
S1: according to JNI format, translating the function name in Java code, and the function name after translation is passed through
Native code in Java calls directly；
S2: find out in the function being translated the variable in need used, and at the C function beginning of translation to these changes
Amount is stated and is defined；
S3: one by one translating Java bytecode according to following logic, until having translated all logics in function:
3.1 if it is logic judgment instruct or operational order (such as: if, goto, addition, position budget etc. instruction), then directly
It connects and translates into corresponding C sentence；
3.2 bytecodes interacted if it is needs with JVM, then translate into corresponding JNI function call；
S4: it if encountering has abnormality processing in Java, can be substituted with label the and goto sentence of C language.
It is illustrated below with a specific example:
Assuming that function foo function its content to be translated is as follows:
public void foo(int a){
If (a > 1) { // sentence 1
bar()；// sentence 2
return；// sentence 3
Code after translation are as follows:
extern"C"JNIEXPORT void JNICALL Java_com_examp 1e_Java2C_foo(JNIEnv}
Envp--, jobject r1, jint r2)
If (r2 > 1) { // sentence 1
// sentence 2bar ()；
Jclass cls=
_jmethodID mid
Mono- > FindClass of env (" com/example/Java2C ")；
Mono- > GetMethodID of=env (cls, " bar ", " () V ")；
Mono- > CallVoidMethod of env (rl, mid)；
return；// sentence 3
In translation is completed, need the public native void foo in script Java code.
In upper example, Java bytecode is automatically translated into C language code, so that the crucial generation in Java bytecode
Code can be hidden into the executable file of particular platform, improve the safety of original program, and can be in several scenes
The a variety of JVM of middle cooperation are used, it is, for example, possible to use in web server, in mobile terminal, IOT it is medium.
Present invention also provides a kind of data processing methods, may include steps of:
S1: the first program is obtained, wherein at least part program code in first program uses object-oriented language
Speech is write；
For example, first program can be the program that the object oriented languages such as java applet, C++ program are write, the first journey
Have in sequence partly or completely program code be to be write by object oriented language.
S2: by least part program code logic judgment instruction and operational order, be translated as using towards
The logic judgment instruction and operational order that procedural language is write, obtain the second program；
In view of easy the problem of cracking present in object oriented language, and procedural language is not easy to be cracked,
Therefore, the instruction of the logic judgment in the program code of object-oriented and operational order etc. can be converted into procedural language generation
A possibility that code, the program obtained in this way is cracked, can be much lower, improves the safety of program.For example, can be converted
For the language in the procedure-orienteds such as C language.
S3: the code that the needs of second program are interacted with virtual machine is translated as local interface function call or original
Raw interface function calls, and obtains object routine.
Because can have some codes for needing to interact with virtual machine in the second program, it can be translated into
Interface function calls or native interface function call, so that finally obtained program can be effectively executed.
When actually realizing, it is also possible to the code that first will need to interact with virtual machine in the first program, is translated as
Local interface function call or native interface function call, obtain the second program, then again by the logic judgment in the second program
Instruction and operational order are translated as the logic judgment write using procedural language instruction and operational order, obtain result journey
