Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments.
In multi-party secure computing systems, different tasks are typically performed by different devices. In the prior art, documents describing the completion mode of each plaintext task and each ciphertext task are independent of each other. In the task execution stage, specific configuration documents for different devices are required (i.e. the specific configuration documents for different tasks are also equivalent), which results in a tedious operation and also reduces the task execution efficiency of the multi-party secure computing system.
In view of this, an embodiment of the present application provides a data processing method, in which, under a condition that it is ensured that each preset task can be completed normally, a document is used to describe a completion manner of multiple preset tasks in a multi-party secure computing system, so that preset-type devices for executing the preset tasks in the multi-party secure computing system can configure the same document (which is equivalent to configuring the same document for each preset task), and compared with a configuration document that needs to be respectively targeted for each type of device in the prior art (which is equivalent to configuring the document for each preset task), an operation flow is simplified, meanwhile, a probability of errors in a configuration process is reduced, and execution efficiency of the multi-party secure computing system and correctness of an execution result are improved.
For ease of understanding, an application scenario of the embodiments of the present application is first described. Fig. 1 is a schematic diagram of a multi-party secure computing system according to an embodiment of the present disclosure. Fig. 1 includes a data providing apparatus 101, a ciphertext computing apparatus 102, and a result receiving apparatus 103.
The data providing apparatus 101 is mainly used for receiving external data, for example, the data providing apparatus 101 may receive the data source1, the data source2, the data source3 and the data source4, and the number of external data that the data providing apparatus 101 can receive is not particularly limited. The data providing apparatus 101 may perform a preprocessing task after receiving the external data, for example, the preprocessing task may be to transform the format of the external data or replace an abnormal value in the external data, and the specific content of the preprocessing task is not particularly limited herein.
The ciphertext computing device 102 is mainly configured to receive ciphertext data preprocessed by the data providing device 102, and then perform ciphertext computation on the ciphertext data.
The result receiving device 103 is mainly used for receiving the result data after ciphertext calculation, for example, the result receiving device 103 may receive the data result1, the data result2, and the result data result3, and the number of the result data that can be received by the result receiving device 103 is not particularly limited. The result receiving device 103 may perform a post-processing task after receiving the result data, for example, the post-processing task may be to perform format conversion on the result data or to eliminate some unnecessary data, and the specific content of the post-processing task is not particularly limited herein.
Based on the architecture diagram of the multi-party secure computing system shown in fig. 1, the following describes a technical solution provided by the embodiment of the present application with reference to the accompanying drawings. Referring to fig. 2, an embodiment of the present application provides a data processing method, where a flow of the method is described as follows:
step 201: the preset type of equipment receives at least one piece of data to be processed.
In this embodiment, the preset type of device may be any one of the data providing device 101, the ciphertext computing device 102, or the result receiving device 103.
Specifically, please refer to fig. 1, for the data providing device 101, at least one data may be a part of or all of the data source1, the data source2, the data source3 and the data source4, or may be other data not labeled in fig. 1, which is not limited herein. For the ciphertext computing device 102, the at least one piece of data may be ciphertext data represented by part or all of func1(source1), func1(source2), func2(source3), and func3(source4), and may be other data that is not labeled in fig. 1, which is not limited herein. For the result receiving device 103, the at least one data may be ciphertext data represented by part or all of the result1, the result2, and the result3, and may also be other data not shown in fig. 1, which is not limited herein.
Step 202: the preset type equipment determines a target modifier corresponding to a first equipment type based on a same prestored document describing the completion modes of a plurality of preset tasks in the multi-party safety computing system and the first equipment type of the equipment; multiple types of modifiers are predefined in the document, each type of modifier being used to characterize a type of device.
In the embodiment of the present application, multiple types of modifiers may be defined in the same document, where each type of modifier is used to characterize one type of device, which is equivalent to establishing a correspondence relationship between the modifier and the type of the device. For example, the data providing apparatus 101 is characterized by an "@ pre" modifier, the ciphertext computing apparatus 102 is characterized by an "@ engine" modifier, and the result receiving apparatus 103 is characterized by an "@ post" modifier. Here, the modifiers used for characterizing different device types are only required to ensure that the above-mentioned documents are not duplicated, and the specific contents of the modifiers are not particularly limited herein. It should be understood that the modifier is represented by @ and is an existing Python syntax, and will not be described here.
Meanwhile, considering that a plurality of preset tasks need to be executed in the multi-party secure computing system, for example, the preset tasks may include: a preprocessing task performed by the data providing device 101, a ciphertext computing task performed by the ciphertext computing device 102, and a post-processing task performed by the result receiving device 103. Therefore, a plurality of function functions, for example, func1, func2, func3, are also defined in the above documents, and the number of function functions is not particularly limited, different function functions in the plurality of function functions are used for executing different preset tasks in the multi-party secure computing system, and each function is allowed to be modified by any type of modifier in a plurality of types of modifiers, and then the function modified by any type of modifier is used for indicating that a device characterized by any type of modifier is allowed to execute the function.
It should be understood that, when the ciphertext computing device 102 in the multi-party secure computing system performs the ciphertext computing task, the processing manner of all the received data is the same, that is, only one function needs to be set for the ciphertext computing task in the above document, and the function is modified by the modifier for representing the ciphertext computing device 102, that is, the modifier for representing the ciphertext computing device 102 only appears once in the above document.
In the multi-party secure computing system, the data providing device 101 and the result receiving device 103 have the same processing mechanism when defining the function, taking the data providing device 101 as an example, in at least one piece of data received by the data providing device 101, each piece of data has a corresponding identity, and different pieces of data are distinguished through the identity. And the preprocessing manners adopted by the at least one piece of data may also be different, so that a plurality of function functions are defined in the document for the preprocessing task, each function corresponds to a different type of preprocessing task, and the function functions are all modified by the modifier for characterizing the data providing device 101, that is, the modifier for characterizing the data providing device 101 may appear in the document many times.
Through the process, the completion mode of describing a plurality of preset tasks in the multi-party security computing system is defined in the same document. And then, the documents can be simultaneously configured to preset types of equipment in the multi-party security computing system, namely, each preset type of equipment is configured with the same document.
Under the condition that the completion modes of a plurality of preset tasks in the multi-party security computing system are described by using the same document, each preset task needs to be ensured to be normally completed. The following is a specific description of how to determine the corresponding modifier when performing a task for different preset types of devices.
Firstly, the method comprises the following steps: the predetermined type of device is the ciphertext computing device 102.
In this embodiment, the ciphertext computing device 102 stores the same document describing multiple preset task completion manners in the multi-party secure computing system in advance, and then, based on the device type of the ciphertext computing device, for example, the first device type, a specific type of modifier corresponding to the first device type, that is, a target modifier, may be determined from multiple types of modifiers defined in the document, so that the ciphertext computing device 102 may know what function should be run next, and thus complete the ciphertext computing task of the ciphertext computing device.
Secondly, the method comprises the following steps: the preset type of device is the data providing device 101 or the result receiving device 103, and the data providing device 101 is taken as an example for explanation.
In this embodiment, the data providing device 101 stores the same document describing multiple preset task completion manners in the multi-party secure computing system in advance, and then, based on the device type of itself, for example, the first device type, at least one first type modifier corresponding to the first device type is determined from multiple types of modifiers defined in the document, where the first type modifier includes an identity of the target data to be processed, and on this basis, according to the received identity of the at least one data, the target modifier may be determined from the at least one first type modifier, so that the data providing device 101 may know what function should be executed next, and thus complete the pre-processing task of itself.
Step 203: and calling the function modified by the target modifier to process at least one piece of data to be processed.
In the embodiment of the application, the corresponding target modifier is determined in the preset type of equipment, so that the data received by the equipment can be processed by using the function modified by the target modifier.
As a possible implementation, the device of the preset type calls the function modified by the target modifier to process at least one piece of data to be processed.
In some embodiments, continuing to take the data providing apparatus 101 as an example, in at least one piece of data received by the data providing apparatus 101, the preprocessing manner required for a part of the data is the same, and at this time, if a plurality of identical function functions are defined in the above document, repeated development may be caused, and the operation is cumbersome. Therefore, in this embodiment of the present application, a part of the first-type modifiers in the at least one first-type modifier may include the identifiers of a plurality of target data to be processed, that is, the plurality of data to be processed may all be processed based on the function modified by the same modifier, so as to implement multiplexing of the function in the same document.
For example, continuing to refer to fig. 1, data source1, data source2, data source3 and data source4 are received by data providing apparatus 101, where the data source1 and data source2 correspond to the same preprocessing manner, so that the modifiers used to characterize data providing apparatus 101 may include the identities of two target data to be processed, i.e., @ pre (source1, source2), at the same time, and then both data source1 and data source2 may perform preprocessing tasks with the same function, e.g., func1(source1) and func1(source 2).
In some embodiments, taking the data providing device 101 and the result receiving device 103 as an example, in at least one data received by each of the two types of devices, the processing manners corresponding to partial data are the same, and at this time, if a plurality of identical function functions are defined in the document, repeated development may be caused, and the same document may not be concise enough. Thus, in the embodiments of the present application, the same function is allowed to be modified by at least one type of modifier.
For example, referring to fig. 1, the data source1, data source2, data source3 and data source4 are received by the data providing apparatus 101, and the data result1, data result2 and data result3 are received by the result receiving apparatus 103, and the data source3 and the data result1 are processed in the same way, that is, both the data source3 and the data result1 are processed by the func1 function, and the func1 function can be modified by @ pre (source3) and @ post (result1) at the same time. For another example, the data source4 and the data result2 are processed in the same way, that is, both the data source4 and the data result2 are processed by the func3 function, and at this time, the func3 function can be modified by @ pre (source4) and @ post (result2) at the same time.
The process of executing the corresponding task by each preset type device in the multi-party secure computing system is described below with reference to fig. 1.
For the data providing device 101, storing the same document describing the completion of various preset tasks in the multi-party secure computing system, when receiving at least one processing data, such as data source1, data source2, data source3 and data source4, the data providing device 101 may determine at least one first type modifier from the document based on its first device type, i.e., the data providing device 101 determines which function functions may be run. Each first-type modifier in the at least one first-type modifier comprises an identity of target data to be processed, and then the target modifier is determined from the at least one first-type modifier according to the received identity of the at least one data, and it should be understood that the identity of the target data to be processed included in the target modifier matches with the identity of the currently received at least one data. That is, the data providing apparatus 101 determines a specific function among a plurality of functions allowed to be executed to preprocess the current at least one data. The data providing device 101 may then call a function modified by the target modifier to pre-process at least one data. For example, data source1 and data source2 are preprocessed with function func1, data source3 is preprocessed with function func2, data source4 is preprocessed with function func3, and the result is output to ciphertext computing device 102 after the preprocessing is completed.
For the ciphertext computing device 102, the same document describing the completion manner of multiple preset tasks in the multi-party secure computing system is stored in advance, when at least one piece of data is received, for example, func1(source1), func1(source2), func2(source3) and func3(source4), the ciphertext computing device 102 may determine a target modifier from the document based on its second device type, and then the ciphertext computing device 102 may call a function modified by the target modifier to perform ciphertext computation on the at least one piece of data, and then output the result, for example, data result1, data result2 and data result 3.
For the result receiving device 103, which stores the same document describing the completion of various preset tasks in the multi-party secure computing system in advance, when receiving at least one processing data, for example, data result1, data result2, and data result3, the result receiving device 103 can determine at least one second type modifier from the document based on its own third device type, that is, the result receiving device 103 determines which function functions can be executed. Each of the at least one second-type modifier includes an identity of the target data to be processed, and then the target modifier is determined from the at least one second-type modifier according to the received identity of the at least one data. That is, the result receiving apparatus 103 determines a specific function among the plurality of functions allowed to be executed to perform the post-processing on the current at least one data. The result receiving device 103 may then call a function modified by the target modifier to post-process the at least one data. For example, data result1 is post-processed using function func2, data result2 is post-processed using function func3, and data result3 is post-processed using function func 4. At this point, a plurality of preset tasks of the multi-party secure computing system are all completed.
