In an embodiment of the present invention, a ciphertext computing engine may register a plug-in service or a plurality of plug-in services. The task scheduling server can respectively send configuration information corresponding to different subtasks to different second ciphertext computing engines so that one second ciphertext computing engine registers one plug-in service to complete one subtask; or, the task scheduling server may send configuration information corresponding to the plurality of subtasks to the same second ciphertext computing engine, so that one second ciphertext computing engine registers a plurality of plug-in services to complete the plurality of subtasks.
In example 2, assume that the ciphertext calculation task is: the data d1 is added with 1 and then stored in d2, and d1 is deleted. Wherein d1, d2, and value 1 are ciphertext.
The ciphertext calculation task comprises the following 3 subtasks: subtask 1, call fetch function takes a key (key value) of k1 data d1. Subtask 2, call store function, store data d2 into key k2, where d2=d1+1. Subtask 3, call del function delete k1 correspondent data d1.
Assume that the ciphertext computing engine participating in the ciphertext computing task includes a computing engine 1, a computing engine 2, and a computing engine 3, and that the data side participating in the ciphertext computing task includes a DS1, the DS1 being configured to provide ciphertext data d1. Wherein, the computing engine 3 is a first ciphertext computing engine, the computing engine 1 and the computing engine 2 are a second ciphertext computing engine, and the subtask 1 is executed by the computing engine 1, and the subtask 2 and the subtask 3 are executed by the computing engine 2. The task scheduling server sends the configuration file of the cryptograph computing task (main task) to the computing engine 3, and the computing engine 3 executes the subtasks by calling the computing engine 1 and the computing engine 2 in the process of executing the main task so as to jointly complete the main task. The task scheduling server sends the configuration file of the subtask 1 of the cryptograph calculation task to the calculation engine 1, and the calculation engine 1 registers the plug-in service of the corresponding calculation function of the subtask 1 so as to realize the calculation function of the subtask 1. The task scheduling server sends the configuration file of the subtask 2 and the configuration file of the subtask 3 of the cryptograph calculation task to the calculation engine 2, and the calculation engine 2 respectively annotates the plug-in service of the calculation function corresponding to the subtask 2 and the plug-in service of the calculation function corresponding to the subtask 3 so as to realize the calculation functions of the subtask 2 and the subtask 3.
In an optional embodiment of the present invention, the ciphertext computing engine participating in the ciphertext computing task registers a corresponding plug-in service according to the received configuration information, including: the second ciphertext computing engine participates in the ciphertext computing task and registers corresponding plug-in services according to the received configuration information;
the method may further comprise: and after registering the corresponding plug-in service, the second ciphertext computing engine starts the registered plug-in service and monitors a call request aiming at the registered plug-in service.
In the embodiment of the invention, the first ciphertext computing engine is used for executing a main task, and the second ciphertext computing engine is used for registering corresponding plug-in services so as to realize one or more sub-tasks in the main task.
The second ciphertext computing engine may be stateless when initially started, and after receiving the configuration file sent by the task scheduling server, a corresponding plug-in service may be registered through the configuration file. After registering the plug-in service, the second ciphertext computing engine has a computing function corresponding to the plug-in service, and the second ciphertext computing engine may start a service to monitor a call request for the plug-in service, and when the call request is monitored, the second ciphertext computing engine starts a thread to execute the computing function corresponding to the plug-in service. Further, after the execution of the computing function is completed, the second ciphertext computing engine may continue to monitor for a call request for the plug-in service to wait for a response to a next call request.
Optionally, after the ciphertext computing task is performed, the second ciphertext computing engine may be reinitialized to a stateless state to register plug-in services of other functions.
In an alternative embodiment of the invention, the computing function may comprise a single computing function or a combined computing function. The single computing function may be a simple computing function such as reading, storing, deleting, etc. of data. The combined computing function may be a complex computing function consisting of multiple single computing functions, such as addition, subtraction, multiplication, division, comparison, ordering, model training, etc. of data.
Further, in practical applications, different computing functions may require different types of computing resources, and the embodiments of the present invention may divide types of plug-in services according to the types of computing resources required by the computing functions. For example, the types of plug-in services include, but are not limited to, compute-intensive and storage-intensive types. The compute intensive type of plug-in service may be implemented by a compute cluster of multiple ciphertext compute engines. The storage-intensive type of plug-in service may be implemented by a storage system consisting of multiple ciphertext computing engines. In particular implementations, ciphertext computing engines of respective plug-in service types may be selected according to different computing functions.
In an optional embodiment of the present invention, the ciphertext computing engine is configured with an interface for triggering remote invocation, and the ciphertext computing engine participating in the ciphertext computing task performs information interaction through the interface for triggering remote invocation, where the interaction information includes at least one of ciphertext data participating in computation, an intermediate result of computation, a invocation request, and an execution state.
According to the embodiment of the invention, the interface triggering remote call is added in the ciphertext computing engine, so that the ciphertext computing engines participating in the ciphertext computing task can directly perform information interaction through the interface, and the transfer of information is not required to be completed through DS or cache every time, so that the processing efficiency of the ciphertext computing task can be improved. Wherein the interactive information includes, but is not limited to, at least one of ciphertext data participating in the calculation, intermediate results of the calculation, call requests, and execution states.
In the embodiment of the invention, the final calculation result of the ciphertext calculation task and the intermediate result are ciphertext, and the plaintext of the data is not exposed in the process of executing the ciphertext calculation task.
It will be appreciated that the embodiments of the present invention do not limit the type of interface that triggers remote invocation. In one example, the data transmission manner of the interface triggering the remote call may be based on a grpc (Google Remote Procedure Call ) protocol, and the interface may be a protobuf (Google Protocol Buffer ) interface.
It should be noted that, the plug-in service may be a user-defined function, and specific content in the plug-in service and a return value of the plug-in service may be defined according to actual requirements. For example, a certain plug-in service may be defined to send data to only one ciphertext computing engine at a time, or a certain plug-in service may be defined to send data to multiple ciphertext computing engines at a time, or a certain plug-in service may be defined not to send data. In addition, whether a certain plug-in service has a return value can be defined, and if the certain plug-in service has the return value, the ciphertext calculation engine where the plug-in service is located can return the return value to the calling party through an interface triggering remote calling.
In an optional embodiment of the present invention, after the task scheduling server sends the configuration information corresponding to the ciphertext computing task to the first ciphertext computing engine and sends the configuration information corresponding to the subtask in the ciphertext computing task to the second ciphertext computing engine, the method may further include:
step S11, the task scheduling server starts the first ciphertext computing engine to execute the ciphertext computing task;
Step S12, when the first ciphertext computing engine executes the subtask in the process of executing the ciphertext computing task, requesting the task scheduling server to acquire address information of a second ciphertext computing engine corresponding to the subtask;
and step S13, the first ciphertext computing engine sends a call request to a second ciphertext computing engine corresponding to the address information through an interface triggering remote call, wherein the call request comprises a plug-in service name and a computing parameter.
In the embodiment of the invention, the first ciphertext computing engine is used for executing the ciphertext computing task (main task), and in the process of executing the ciphertext computing task, each subtask in the ciphertext computing task is executed by calling the corresponding second ciphertext computing engine so as to jointly complete the ciphertext computing task.
Different second ciphertext computing engines register different plug-in services, which can be user-defined functions, each plug-in service corresponds to a plug-in service name, and the plug-in service names can be used when other ciphertext computing engines call the plug-in service.
When the first ciphertext computing engine executes the subtasks, the task scheduling server requests to acquire the address information of a second ciphertext computing engine of the subtasks to be executed, after the address information returned by the task scheduling server is received, the first ciphertext computing engine sends a calling request to the second ciphertext computing engine corresponding to the address information through triggering a remote calling interface so as to call plug-in services registered in the second ciphertext computing engine and execute the corresponding subtasks.
The call request may carry a plug-in service name and a calculation parameter. The name of the plug-in service is the name of the plug-in service needing to be called. The computing parameters are the incoming parameters of the plug-in service that needs to be invoked, and the plug-in service can execute corresponding computing functions according to the incoming computing parameters. The call request may include, in addition to the plug-in service name and the calculation parameter, other parameters, such as the name of the second ciphertext calculation engine to be called, and the like.
In the embodiment of the invention, in the process of executing a ciphertext computing task (a main task), the first ciphertext computing engine can acquire the identifier of a second ciphertext computing engine of a subtask to be executed from configuration information of the main task, further can request a task scheduling server to acquire address information of the second ciphertext computing engine corresponding to the identifier, and after receiving the address information returned by the task scheduling server, the first ciphertext computing engine sends a call request to the second ciphertext computing engine corresponding to the address information by triggering a remote call interface. The address information of the second ciphertext computing engine to perform the subtask may include an IP (Internet Protocol ) address and a port number of each ciphertext computing node in the second ciphertext computing engine.
Taking example 2 as an example, the ciphertext calculation task (master task) is: the data d1 is added with 1 and then stored in d2, and d1 is deleted. Wherein d1, d2, and value 1 are ciphertext. The ciphertext computing task comprises 3 subtasks, the task scheduling server distributes a main task to the computing engine 3, distributes the subtask 1 to the computing engine 1, and distributes the subtask 2 and the subtask 3 to the computing engine 2. The task scheduling server sends the configuration file of subtask 1 to compute engine 1 and the configuration file of subtask 2 and the configuration file of subtask 3 to compute engine 2.
The calculation engine 1 and the calculation engine 2 register corresponding plug-in services according to the respective received configuration files, and monitor call requests for the registered plug-in services, respectively. Let the plug-in service of the computing function corresponding to the subtask 1 be denoted as handler1, the plug-in service of the computing function corresponding to the subtask 2 be denoted as handler2, and the plug-in service of the computing function corresponding to the subtask 3 be denoted as handler3. In example 2, compute engine 1 registers handler1, compute engine 2 registers handler2 and handler3. The corresponding calculation function of the handler1 is as follows: data d1 with a key k1 is taken. The corresponding calculation function of the handler2 is as follows: d2 is stored in k2. The corresponding calculation function of the handler3 is as follows: deleting the data d1 corresponding to k 1.
After the computing engine 3 starts the main task, the computing engine 1 needs to be called to execute the subtask 1 first, specifically, the computing engine 3 sends the identification of the computing engine 1 to the task scheduling server, and requests to acquire the address information of the computing engine 1. After the computing engine 3 receives the address information of the computing engine 1 returned by the task scheduling server, a call request for handler1 is sent to the computing engine 1 by triggering an interface of remote call, and the call request includes a plug-in service name fetch and a computing parameter k1. After the computing engine 1 monitors the call request for the handler1, the thread is started to execute the computing function of the handler1 in response to the call request, for example, data d1 with key k1 is obtained from the DS1, and the data d1 is returned to the computing engine 3 through an interface triggering remote call.
In an optional embodiment of the present invention, when the call request for the registered plug-in service is monitored, executing a computing function of the plug-in service corresponding to the call request includes: when the second ciphertext computing engine corresponding to the address information monitors a calling request, calling the plug-in service corresponding to the plug-in service name to execute a corresponding computing function on the computing parameter;
The method further comprises the steps of: and the second ciphertext computing engine corresponding to the address information returns an execution state to the first ciphertext computing engine after executing the corresponding computing function.
After the first ciphertext computing engine (such as computing engine 3) obtains the address information of the second ciphertext computing engine (such as computing engine 1) of the subtask (such as subtask 1) to be executed, a call request is sent to the second ciphertext computing engine (computing engine 1) corresponding to the address information, and the call request comprises a plug-in service name (such as fetch) and a computing parameter (k 1). When the calculation engine 1 monitors the call request, the plug-in service (handler 1) corresponding to the plug-in service name (fetch) is called to execute a corresponding calculation function on the calculation parameter (k 1), namely, the value of (fetch) k1 is read.
In the embodiment of the invention, after the second ciphertext computing engine responds to the call request to execute the corresponding computing function, the second ciphertext computing engine can return the execution state to the first ciphertext computing engine in the process of executing the computing function and after the execution is completed. For example, the execution state may be returned to the first ciphertext computing engine periodically, which may include executing, completed, incomplete, exception, and the like. The first ciphertext computing engine may determine whether to perform a next computation based on an execution state returned by the invoked second ciphertext computing engine.
Further, the first ciphertext computing engine may also periodically feed back an execution state of the first ciphertext computing engine to the task scheduling server, so that the task scheduling server may determine whether to execute the task scheduling of the next step according to the execution state fed back by the first ciphertext computing engine.
In order to describe the task processing method of the embodiment of the present invention more clearly, still taking example 2 as an example, the steps of invoking the second ciphertext computing engine to execute each subtask by the first ciphertext computing engine are as follows:
step 1, the computing engine 3 first needs to call the computing engine 1 to execute the subtask 1, specifically, the computing engine 3 sends the identification of the computing engine 1 to the task scheduling server, and requests to acquire the address information of the computing engine 1. After the computing engine 3 receives the address information of the computing engine 1 returned by the task scheduling server, a call request for handler1 is sent to the computing engine 1 by triggering an interface of remote call, and the call request includes a plug-in service name fetch and a computing parameter k1. After the computing engine 1 monitors the call request for the handler1, the thread is started to execute the computing function of the handler1 in response to the call request, for example, data d1 with key k1 is obtained from the DS1, and the data d1 is returned to the computing engine 3 through an interface triggering remote call.
Step 2, after the computing engine 3 receives the data d1 through the interface triggering the remote call, the computing engine performs the operation of computing d2=d1+1, and generates a key value k2.
Step 3, the computing engine 3 needs to call the computing engine 2 to execute the subtask 2 next, specifically, the computing engine 3 sends the identification of the computing engine 2 to the task scheduling server, and requests to acquire the address information of the computing engine 2. After the computing engine 3 receives the address information of the computing engine 2 returned by the task scheduling server, a call request for handler2 is sent to the computing engine 2 by triggering an interface of remote call, and the call request includes a plug-in service name store and computing parameters k2 and d2. After the calculation engine 2 monitors the call request for the handler2, in response to the call request, the thread is started to execute the calculation function of the handler2, d2 is stored in the key value k2, and the completed execution state is returned to the calculation engine 3.
Step 4, after the computing engine 3 receives the completed execution state returned by the computing engine 2, the computing engine 2 needs to be called to execute the subtask 3, specifically, the computing engine 3 sends the identification of the computing engine 2 to the task scheduling server, and requests to acquire the address information of the computing engine 2. After the computing engine 3 receives the address information of the computing engine 2 returned by the task scheduling server, a call request for handler3 is sent to the computing engine 2 by triggering an interface of remote call, and the call request includes a plug-in service name del and a computing parameter k1. After the computing engine 2 monitors the call request for the handler3, the thread is started to execute the computing function of the handler3 in response to the call request, the data d1 corresponding to k1 is deleted, and the completed execution state is returned to the computing engine 3.
And step 5, the calculation engine 3 returns the completed execution state to the task scheduling server, and the ciphertext calculation task is completed.
Optionally, after the first ciphertext computing engine obtains the address information of the second ciphertext computing engine returned by the task scheduling server, the first ciphertext computing engine may store a mapping relationship between the address information of the second ciphertext computing engine and the identifier of the second ciphertext computing engine. In this way, before the first ciphertext computing engine sends the identifier of the second ciphertext computing engine to be executed for the subtask to the task scheduling server and requests to acquire the address information of the second ciphertext computing engine corresponding to the subtask, whether the address information of the second ciphertext computing engine corresponding to the subtask exists or not can be queried in the stored mapping relation, and if so, the task scheduling server does not need to request to acquire the address information of the second ciphertext computing engine corresponding to the subtask.
For example, in the above step 3, after the computing engine 3 receives the address information of the computing engine 2 returned by the task scheduling server, the mapping relationship between the address information of the computing engine 2 and the identity of the computing engine 2 may be recorded. In step 4, the computing engine 3 can directly obtain the address information of the computing engine 2 according to the mapping relation, so that the interaction between the second ciphertext computing engine and the task scheduling server can be reduced, the data transmission pressure is reduced, and the computing efficiency is improved.
It should be noted that, in the above example 2, taking the execution of the subtasks by the two second ciphertext computing engines of the computing engine 1 and the computing engine 2 as an example, in practical application, the number of subtasks decomposed by one ciphertext computing task and the number of the second ciphertext computing engines are not limited. Referring to fig. 2, a flow chart of task processing by using n second ciphertext computing engines according to an embodiment of the invention is shown, where n is a positive integer. As shown in fig. 2, the second ciphertext computing engine includes computing engine 1, computing engines 2, …, and computing engine n, wherein computing engine 1 registers plug-in service handler1 according to configuration information 1, computing engine 2 registers plug-in service handler2 according to configuration information 2, and so on, computing engine n registers plug-in service handler according to configuration information n. Wherein each second ciphertext computing engine may be controlled by a task controller. It will be appreciated that the first ciphertext computing engine (not shown in fig. 2) may also be controlled by a task controller.
As shown in fig. 2, the embodiment of the present invention can implement different computing functions through a custom plug-in service (handler 1-handler), so that in a ciphertext computing system, one ciphertext computing task can be decomposed into a plurality of subtasks, and the plurality of subtasks are distributed to at least one (e.g., n) second ciphertext computing engines, so that the subtasks in one ciphertext computing task can be connected in series in a plug-in manner according to the custom requirement, thereby implementing the streaming processing of the ciphertext computing task, reducing the computing pressure of each ciphertext computing engine (including the first ciphertext computing engine and the second ciphertext computing engine) participating in the ciphertext computing task, and improving the execution efficiency of the ciphertext computing task.
In summary, in the multiparty secure computing system, the embodiment of the invention transmits the configuration information for registering the plug-in service to at least one ciphertext computing engine participating in the ciphertext computing task, so that the ciphertext computing engine registering the plug-in service can realize the corresponding computing function, and does not need professional personnel to carry out complex code programming under the framework of the existing computing node, thereby reducing the difficulty of expanding the computing function of the ciphertext computing node and reducing the development cost. Further, the ciphertext computing engine that registers the plug-in service may monitor a call request for the registered plug-in service and, upon monitoring the call request for the registered plug-in service, perform a computing function of the plug-in service to which the call request corresponds. That is, the ciphertext computing engine registered with the plug-in service may respond to the call of other ciphertext computing engines to implement the streaming processing of the task, thereby improving the execution efficiency of the task.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred embodiments, and that the acts are not necessarily required by the embodiments of the invention.
