All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Method embodiment
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a code execution method according to the present invention is shown, where the method may specifically include the following steps:
102, interpreting and compiling the cipher text interpreter source code by using the preset tool chain to obtain a target interpreter with a just-in-time compiling function;
and 103, executing the ciphertext operation source code by using the target interpreter.
The embodiment of the invention realizes the target interpreter with the immediate compiling function based on the preset tool chain, and the execution process of the ciphertext operation source code can be accelerated by utilizing the target interpreter to execute the ciphertext operation source code, so that the efficiency of executing the ciphertext operation source code is improved.
The ciphertext operation source code refers to a program source code for the ciphertext processing system to perform data processing on ciphertext data. The data processing for the ciphertext data includes but is not limited to: and data related operations such as cleaning, calculation, analysis, model training, storage, database query and the like of the data are realized based on the ciphertext. It should be noted that the specific type of data processing is not limited by the embodiments of the present invention. The ciphertext processing system may be implemented in different programming languages, and may perform privacy operations on ciphertext data based on a ciphertext data processing algorithm, for example, the ciphertext processing system may be a multi-party secure computing system.
The privacy operation refers to an operation performed on data based on a ciphertext, and the privacy operation may be implemented by a data processing algorithm based on the ciphertext, where the data processing algorithm may include algorithms such as data calculation, model training, database query, and the like. In the privacy operation process of the data, the data exists in a ciphertext mode, and the plaintext of the data cannot be exposed. Optionally, the privacy operations may include any one or more of: cipher text based computing operations, cipher text based model training, cipher text based database query operations, and the like.
For example, the privacy operations may include: and performing calculation operations such as addition, subtraction, multiplication, division, averaging and the like on the data ciphertext, performing comparison operation on the data ciphertext, performing model training and prediction such as machine learning and artificial intelligence by using the data ciphertext, performing database query operation on the data ciphertext, and the like.
It should be noted that the privacy operation may be implemented by invoking a ciphertext computing system, where the ciphertext computing system may be based on a multi-party secure computing protocol, data participating in the computation includes ciphertext data, and an intermediate result and a final computation result generated in the computation process are also ciphertext data. In the calculation process based on the ciphertext, the data plaintext is not exposed, and the privacy security of the data can be ensured.
The privacy operation may be used for data processing of ciphertext data. In some examples, the ciphertext data is a private data, and the technician stores a program containing a business logic for processing the private data in the task management platform in advance, wherein the business logic describes a processing process of the private data through a computer program language, and the processing process can contain one or more computing tasks. The business logic refers to a process that a technician performs data processing on private data by using one or more computing tasks and obtains the private data according to a natural law. For example, one business logic comprises: under the condition that the clear text of the credit rating values of the enterprises is not known, a group of enterprises which are already ranked according to the credit rating scores and another group of enterprises which are already ranked according to the credit rating scores are merged, and the merging process directly completes the ranking. Another business logic includes: under the condition that the repayment ability score plaintext of each user is not known, a group of users which are sequenced according to the repayment ability score and another group of users which are sequenced according to the repayment ability score are combined, and the sequence is directly completed in the combining process. The scheme of the invention is suitable for any privacy operation scene based on the ciphertext.
For the ciphertext operation source code, a ciphertext interpreter source code needs to be defined and implemented, and the ciphertext interpreter source code is used for interpreting the ciphertext operation source code. In order to solve the problem that the efficiency of executing the ciphertext operation source code by the interpreter is low, the embodiment of the invention realizes the ciphertext interpreter source code according to the grammar rule defined by the preset tool chain. The preset tool chain is a tool which can convert the source code of the ciphertext interpreter which accords with the grammar rule into a target interpreter, and the target interpreter is also provided with a JIT just-in-time compiling function on the basis of the interpreting function of a general interpreter.
Specifically, the ciphertext interpreter source code may be implemented based on an interpreted language, and the ciphertext interpreter source code conforms to the grammar rules defined by the preset toolchain. In the embodiment of the present invention, the interpreted language supported by the preset toolchain is referred to as a front-end language. And interpreting the ciphertext interpreter source code realized by the front-end language through a preset tool chain to obtain a rear-end source code of the target interpreter with the just-in-time compiling function, and compiling the rear-end source code through the preset tool chain to generate the target interpreter with the just-in-time compiling function.
In the embodiment of the present invention, the ciphertext operation source code may be implemented based on an interpreted Language, where the interpreted Language includes, but is not limited to, Python Language, SQL (Structured Query Language), and may also be any one of the interpreted languages newly invented in the future.
The target interpreter generated by the embodiment of the invention can execute the ciphertext operation source code in an interpretation and just-in-time compilation acceleration mode. Specifically, the target interpreter may interpret and compile the ciphertext operation source code in real-time to generate machine code, and then automatically execute the machine code. Compared with the mode of executing the ciphertext operation source code while converting each time, the efficiency of executing the ciphertext operation source code can be greatly improved.
In an optional embodiment of the present invention, the interpreting and compiling the ciphertext interpreter source code by using the preset tool chain to obtain a target interpreter with a just-in-time compiling function includes:
step S11, determining the interpretation type language type of the source code of the ciphertext interpreter;
and step S12, according to the grammar rule of the interpreted language type, the preset tool chain is used for interpreting and compiling the ciphertext interpreter source code to generate a target interpreter which is matched with the interpreted language type and has a just-in-time compiling function.
In the embodiment of the invention, the preset tool chain can convert the source codes of the ciphertext interpreters realized by different interpretation type language types into the target interpreters of the corresponding interpretation type language types. For example, for the ciphertext operation source code a implemented by the interpreted language a, a ciphertext interpreter source code a matching the interpreted language a may be written, and the ciphertext interpreter source code a may be used to interpret the ciphertext operation source code a. And interpreting and compiling the ciphertext interpreter source code A through a preset tool chain to obtain the target interpreter A which is matched with the interpreted language A and has the just-in-time compiling function. The target interpreter a may execute the ciphertext operation source code a.
For another example, for the ciphertext operation source code B implemented by the interpretive language B, a ciphertext interpreter source code B matched with the interpretive language B may be written, and the ciphertext interpreter source code B may be used to interpret the ciphertext operation source code B. And interpreting and compiling the ciphertext interpreter source code B through a preset tool chain to obtain a target interpreter B which is matched with the interpreted language B and has a just-in-time compiling function. The target interpreter B may execute the ciphertext operation source code B.
By the embodiment of the invention, for the ciphertext operation source codes realized by different interpretation type languages, ciphertext interpreter source codes conforming to grammar rules of different interpretation type languages can be compiled, and the ciphertext interpreter source codes realized by different interpretation type languages are converted into target interpreters of corresponding interpretation type language types through the preset tool chain. For the ciphertext operation source code realized by the same type of interpretation type language, the universal ciphertext interpreter source code can be realized, and only a target interpreter needs to be realized once.
For example, the ciphertext interpreter source code a may be used as the ciphertext operation source code C implemented by the interpreted language a. And interpreting and compiling the ciphertext interpreter source code A through a preset tool chain to obtain a target interpreter C which is matched with the interpreted language A and has a just-in-time compiling function. The target interpreter C may execute the ciphertext operation source code C.
Compared with the existing compiler which can only adapt to a specific language, the preset tool chain of the embodiment of the invention can support the front-end source code of any interpretation type language type and generate the target interpreter which accords with the corresponding interpretation type language type. By the embodiment of the invention, the target interpreter of the corresponding interpreted language type can be generated by the preset tool chain only by realizing the front-end source codes of different types of interpreted languages, the application range of the target interpreter can be expanded, and the cost of redevelopment can be reduced.
In an optional embodiment of the present invention, the preset tool chain may include a flowchart analyzer, an annotation generator, a back-end generator, and a static compiler, and the interpreting and compiling the ciphertext interpreter source code by using the preset tool chain to obtain a target interpreter with a just-in-time compiling function includes:
step S21, using the flow chart analyzer to perform syntactic analysis on the ciphertext interpreter source code, and generating a flow chart of the ciphertext interpreter source code;
step S22, analyzing and labeling each element in the flowchart by using the annotation generator to obtain a flowchart with annotation;
step S23, traversing the annotated flowchart by the back-end generator, and translating the flowchart into a back-end source code;
step S24, compiling the back-end source code by using the static compiler to obtain a binary file;
and step S25, linking the binary file with the static compiler to obtain a target interpreter with a just-in-time compiling function.
Referring to fig. 2, a flow diagram of generating an object interpreter with just-in-time compiling function through a preset tool chain according to the present invention is shown. As shown in fig. 2, the preset toolchain includes the following modules: a flow chart analyzer 201, an annotation generator 202, a back-end generator 203, and a static compiler 204. Wherein, the flow chart analyzer, the annotation generator and the back-end generator are used for the interpretation stage of the source code of the ciphertext interpreter; the static compiler is used in the compilation stage of the ciphertext interpreter source code.
The flow chart analyzer is used for carrying out syntactic analysis on the ciphertext interpreter source code and generating the flow chart of the ciphertext interpreter source code. The flow chart is constructed by the flow chart analyzer based on the functions in the source code of the ciphertext interpreter, the flow chart can comprise a function call chart and control flow charts of the functions, and the flow chart describes executable paths and function call relations of the source code of the ciphertext interpreter. The elements in the flow chart include, but are not limited to, sub-flow charts, nodes (used to represent functions in the ciphertext interpreter source code), edges (or called connections), variables, and constants.
And the annotation generator is used for analyzing and labeling each element in the flow chart to obtain the flow chart with annotation. The annotations may be used to describe the object types to which the elements correspond, including but not limited to base objects, certificates, strings, tuples, variables and containers, user-defined classes and instances.
And the back-end generator is used for traversing the annotated flow chart and translating the flow chart into back-end source codes which can be identified by the static compiler. Specifically, the back-end generator may translate the annotated flowchart into a back-end source code through a series of processing flows, such as explicit static type conversion, back-end optimization, explicit exception handling, memory recovery management, and language translation. The annotated flow chart is marked with the data types of all the elements, and the back-end generator can convert the data types of all the elements in the flow chart into the static types which can be identified by the static compiler through static type conversion. The back-end source code may be ANSI C language code. It is to be understood that the language type of the intermediate code is not limited by the embodiments of the present invention.
And the static compiler is used for compiling the back-end source code to obtain a binary file.
After the source code of the ciphertext interpreter is interpreted and compiled, the compiled binary file is linked with the static compiler, so that an executable program of the target interpreter can be generated, the target interpreter has a just-in-time compiling function, and the just-in-time compiling function of the target interpreter can be realized by the static compiler.
In an alternative embodiment of the present invention, the preset toolchain may be implemented in an interpreted language with static data type annotation. The interpreted language with static data type label defines a branch of the interpreted language with data type label. For example, for Python language, no data type needs to be defined in the syntax, but in order to enable the preset tool chain to realize the function of adding a just-in-time compiler in the target interpreter, the preset tool chain is required to forcibly require data type labeling and conversion. That is, the preset tool chain has the functions of marking the data type and performing forced conversion on the marking data type. In particular, the function of annotating data types can be implemented by an annotation generator, which can annotate data types of elements in the flow chart. The forced transformation function may be implemented by a back-end generator that may force transformation of the data types of the elements in the annotated flow-chart into data types recognizable to the static compiler.
In an embodiment of the present invention, the interpreted language with static data type markup may be a Python language branch, and the language branch defines mandatory data type markup.
In an optional embodiment of the present invention, a basic grammar model of a ciphertext computing interpretation type code is defined in the preset tool chain, and a ciphertext algorithm module is loaded based on the basic grammar model; the interpreting and compiling the cipher text interpreter source code by using the preset tool chain to obtain the target interpreter with the just-in-time compiling function, comprising the following steps:
and interpreting the source code of the ciphertext interpreter by using the preset tool chain, converting the source code of the ciphertext interpreter, which contains or calls the ciphertext algorithm module, into a flow chart which accords with the grammar rule of the preset tool chain, and embedding the ciphertext algorithm module in the generated target interpreter through the compiling process of the preset tool chain.
In the embodiment of the invention, a basic grammar model of a ciphertext computing interpretation type code is defined in the preset tool chain. The ciphertext calculation interpreted code refers to a source code of ciphertext calculation realized based on the interpreted code in the ciphertext operation source code. The basic grammar model includes, but is not limited to, a flow model (e.g., constant model, variable model, control model, etc.), an object model (integer, floating point, boolean, string, list, dictionary, function, class, object). Based on the basic grammar model of the ciphertext computing interpretation type code, an extension module can be loaded in a preset tool chain, and the extension module comprises but is not limited to a ciphertext algorithm module.
The ciphertext algorithm module may be used to implement privacy operations. The ciphertext algorithm module comprises a ciphertext algorithm function for calculating the ciphertext data. In one example, the ciphertext algorithm module may include a pnumpy module and a ptorch module. The pnumpy module includes the following ciphertext algorithm functions: array operation functions, mathematical functions, linear algebraic functions, statistical functions, random number generation functions, and the like. The ptorch module comprises the following ciphertext algorithm functions: convolution functions, pooling functions, recursive functions, activation functions, and the like.
In a specific implementation, the ciphertext algorithm module may be loaded in a preset tool chain in a manner of declaration and loading based on the basic grammar model. The embodiment of the invention does not limit the implementation language of the ciphertext algorithm function in the ciphertext algorithm module. For example, the ciphertext algorithm function may be implemented based on a C + + language, and compared with a Python language, the operation speed of the privacy operation may be greatly increased, so that the efficiency of ciphertext processing may be improved.
Since the ciphertext algorithm module is loaded in the preset tool chain, in the process of interpreting the ciphertext interpreter source code through the preset tool chain, as in step S21, when the source code of the ciphertext interpreter includes or calls the source code of the ciphertext algorithm library, the source code may be converted into a flowchart conforming to the grammar rule of the preset tool chain, and then the ciphertext algorithm library is built in the generated target interpreter through a series of processing procedures of the preset tool chain shown in fig. 2.
In the embodiment of the invention, all basic grammar models of the ciphertext computing interpretation type code are defined in the preset tool chain, and the ciphertext algorithm module can expand the grammar model of the ciphertext algorithm function according to the basic grammar models. The preset tool chain converts the cipher text interpreter source code facing the user into a grammar model conforming to the preset tool chain, a target interpreter is finally generated through the interpretation and compilation process of the preset tool chain, and the special cipher text algorithm module is built in the target interpreter, so that the cipher text algorithm module can be hidden from the user, and the information leakage of the cipher text algorithm module can be prevented.
In an optional embodiment of the present invention, the executing the ciphertext operation source code with the target interpreter includes:
step S31, the target interpreter is used for interpreting the ciphertext operation source code, the interpreted language in the ciphertext operation source code is converted into a static language code compatible with a just-in-time compiler, and the static language code is compiled into byte codes;
and step S32, compiling the bytecode into machine code and executing the machine code.
In the embodiment of the invention, the target interpreter can execute the ciphertext operation source code in an interpretation and just-in-time compilation acceleration mode.
Specifically, the target interpreter includes an interpretation stage and a compilation stage when executing the ciphertext operation source code. In the interpretation stage, the target interpreter interprets the ciphertext operation source code, converts an interpretation type language in the ciphertext operation source code into a static language code compatible with a just-in-time compiler, and compiles the static language code into a byte code; in the compiling stage, the target interpreter compiles the bytecode into machine code and automatically executes the machine code.
The bytecode is a binary file containing an execution program and composed of a sequence of opcode/data pairs. Bytecode is an intermediate code that is more abstract than machine code and requires translation by an interpreter before it becomes machine code. Machine code is an instruction that a CPU (Central Processing Unit) can directly interpret. The machine code is related to hardware and the like, and the machine code supported by different CPU architectures is different.
Specifically, in the stage of interpreting the ciphertext operation source code, the target interpreter with the just-in-time compiling function performs syntax analysis on the ciphertext operation source code, constructs a flow chart of the ciphertext operation source code according to functions in the ciphertext operation source code, and analyzes and labels each element in the flow chart to obtain the flow chart with annotations; then, static language analysis is carried out on the flow chart with the annotation, and each element in the flow chart is translated into a static language code to obtain the flow chart with the static language code; and compiling the flow chart with the static language codes, compiling the static language codes in the flow chart into machine codes, and obtaining the flow chart with the byte codes. In the execution stage of the cryptograph operation source code, the target interpreter with the just-in-time compiling function can accelerate the execution of the cryptograph operation source code according to the flow chart with the byte codes.
In an optional embodiment of the invention, the method further comprises:
maintaining a memory mapping table and a counter, wherein the memory mapping table records the mapping relation between the bytecode and the machine code corresponding to each node of the flow chart of the ciphertext operation source code, and the counter is used for recording the execution times of each node of the flow chart of the ciphertext operation source code;
the compiling the bytecode into a machine code and executing the machine code includes:
step S41, determining a target node with the counter value larger than a preset threshold value;
step S42, compiling the byte code corresponding to the target node into a machine code, and updating the memory mapping table;
step S43, when a target node in the flowchart of the ciphertext operation source code is executed, obtaining a target address of a machine code corresponding to a bytecode of the target node by querying the memory mapping table;
and step S44, executing the machine code corresponding to the target address.
In the embodiment of the invention, in the process of executing the ciphertext operation source code by using the target interpreter, the flowchart with the byte code is generated in the interpretation stage, and the flowchart with the byte code is processed and executed by using the operation management rule of the just-in-time compiler in the interpretation stage.
The operation management rule of the just-in-time compiler means: by maintaining a memory mapping table and a counter, when the value of the counter is greater than a preset threshold value, a static compiler in a target interpreter is used for compiling the byte codes of the corresponding nodes in the flow chart to generate machine codes, and the memory mapping table is updated. The memory mapping table is used for recording mapping relations between byte codes and machine codes corresponding to nodes of a flow chart of the ciphertext operation source codes, and the counter is used for recording the execution times of the nodes of the flow chart of the ciphertext operation source codes.
The preset threshold value can be set according to actual requirements, and the counter value of the target node is greater than the preset threshold value, which indicates that the execution times of the target node in the whole ciphertext operation source code are more. In this way, when the target node in the flow chart of the ciphertext operation source code is executed again, the target address of the machine code corresponding to the bytecode of the target node can be obtained by querying the memory mapping table, and then the machine code corresponding to the target address can be directly executed. For the target node, the process of converting the code into the byte code and then converting the byte code into the machine code does not need to be executed again each time, and the execution speed of the ciphertext operation source code can be further accelerated.
In the execution stage of the ciphertext operation source code, the target interpreter with the just-in-time compiling function executes the flow chart with the byte code and maintains a memory mapping table and a counter. The mapping relation between the byte codes and the machine codes corresponding to the nodes of the flow chart of the ciphertext operation source codes is recorded in the memory mapping table, and the counter is used for recording the execution times of the nodes of the flow chart of the ciphertext operation source codes. When the counter of a certain node in the flow chart exceeds a preset threshold value, the node is determined to be a target node, a target interpreter with a just-in-time compiling function compiles the byte code corresponding to the target node to generate a machine code, and the memory mapping table is updated. When the target node in the flow chart is executed again, the machine code can be directly executed by inquiring the target address of the machine code corresponding to the bytecode of the target node in the memory mapping table.
In summary, the present invention implements a ciphertext interpreter source code according to a grammar rule defined by a preset toolchain, where the ciphertext interpreter source code is used to interpret a ciphertext operation source code; the preset tool chain is a tool which can convert the ciphertext interpreter source code which accords with the grammar rule into a target interpreter, and the target interpreter with the immediate compiling function can be obtained by interpreting and compiling the ciphertext interpreter source code by using the preset tool chain. That is, the target interpreter has a JIT just-in-time compiling function in addition to the interpreting function of the general interpreter. Therefore, in the process of executing the ciphertext operation source code by using the target interpreter, the target interpreter can interpret and immediately compile the ciphertext operation source code to generate machine code, and then automatically execute the machine code. Compared with the mode of executing the ciphertext operation source code while converting each time, the efficiency of executing the ciphertext operation source code can be greatly improved.
