[0021] In the above embodiments, encrypting the serialized data before transmitting it can improve the security of data transmission.

[0022] In an optional implementation, sending the parameters required for the gRPC communication protocol invocation method to the server includes: sending the parameters required for the gRPC communication protocol invocation method and the interface address to the server, wherein the interface address is used to indicate the communication interface with the server when communicating based on the gRPC communication protocol.

[0024] The step of receiving the return value based on the calling method sent by the server and parsing the return value to obtain the return data structure information of the calling method of the GPRC communication protocol includes: deserializing the return value to obtain the return data structure information of the calling method of the GPRC communication protocol.

[0025] In an optional implementation, the method further includes: obtaining a data stream identifier; constructing a sequential sequence based on the data stream identifier, wherein the sequential sequence is used to record the position of the data stream communicating with the server.

[0038] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0039] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Currently, the communication method based on the gRPC communication protocol is relatively common on the server side and is easy to develop.

[0041] However, the inventors of this application have learned through research that while communication methods based on the gRPC communication protocol have the aforementioned advantages, they also suffer from vulnerability to malicious software. The main reason for this vulnerability is that clients using the gRPC communication protocol can only use user-level support libraries for connection and communication. However, the user-level implementation is susceptible to malware attack, which can even allow malware to obtain and tamper with communication content. Furthermore, existing programs that use the gRPC communication protocol for network communication run at the user level, making them highly vulnerable to malicious programs that can damage and modify them, significantly reducing communication security.

[0042] Based on the above research, this application provides a method for communication based on the gRPC communication protocol. This method achieves the function of communication based on gRPC at the Windows kernel layer by implementing the relevant protocol content of HTTP2 and gRPC from the bottom layer, thereby improving the communication speed and greatly improving the communication security.

[0043] The following section introduces the concepts involved in this application before describing the communication method based on the GRPC communication protocol provided in this application:

[0044] GRPC: short for Google Remote Procedure Call, is a high-performance, general-purpose, open-source remote procedure call framework developed by Google, primarily designed based on the HTTP / 2 protocol standard;

[0045] HTTP / 2: Hypertext Transfer Protocol version 2.0, which specifies the format of messages transmitted between clients and servers;

[0046] Kernel layer: It has the highest execution privileges and is at the same level as the system kernel code, but the APIs (Application Program Interfaces) and types provided by the system are subject to certain restrictions;

[0047] User layer: The layer where user applications reside. The system provides a rich set of interfaces and types, so problems will not affect the operation of the system.

[0048] To facilitate understanding of this embodiment, the operating environment for implementing the communication method based on the GRPC communication protocol disclosed in this application embodiment will be described in detail first.

[0049] like Figure 1 The diagram illustrates the interaction between a server 110 and a client terminal 120 according to an embodiment of this application. The server 110 establishes a communication connection with one or more client terminals 120 via a network for data communication or interaction. The server 110 can be a web server, a database server, etc. The client terminal 120 can be a personal computer (PC), tablet computer, smartphone, personal digital assistant (PDA), etc.

[0050] In this embodiment, the client terminal 120 may have a client running on it.

[0051] Server 110 can run a server-side component that can receive data from clients and establish a GRPC communication protocol with them to enable communication based on the GRPC protocol.

[0052] like Figure 2 The diagram shown is a block illustration of an electronic device. The electronic device 200 may include a memory 211 and a processor 213. Those skilled in the art will understand that... Figure 2 The structure shown is for illustrative purposes only and does not limit the structure of the electronic device 200. For example, the electronic device 200 may also include components that are more... Figure 2 The more or fewer components shown, or having the same Figure 2 The different configurations shown.

[0053] For example, Figure 1 The server 110 and client terminal 120 shown may include Figure 2 The components of the electronic device 200 shown can, of course, include more than [other components] if there are additional functional requirements. Figure 2 The electronic device shown has 200 more components.

[0054] The memory 211 and processor 213 described above are electrically connected directly or indirectly to enable data transmission or interaction. For example, these components can be electrically connected to each other via one or more communication buses or signal lines. The processor 213 described above is used to execute executable modules stored in the memory.

The methods executed by the electronic device 200, as defined in any embodiment of this application, can be applied to or implemented by the processor 213.

[0056] The aforementioned processor 213 may be an integrated circuit chip with signal processing capabilities. The processor 213 may be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it may also be a digital signal processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor may be a microprocessor or any conventional processor.

[0057] The electronic device 200 in this embodiment can be used to execute various steps in the various methods provided in the embodiments of this application. The implementation process of the method for communication based on the gRPC communication protocol is described in detail below through several embodiments.

[0058] Please see Figure 3 This is a flowchart illustrating a method for communication based on the gRPC communication protocol provided in an embodiment of this application. The method for communication based on the gRPC communication protocol provided in this embodiment can be applied to the above-mentioned... Figure 1 Specifically, the client terminal shown runs a client application, which can be used to execute the steps in the communication method based on the GPRC communication protocol provided in this embodiment. The following will describe... Figure 3 The specific process shown will be explained in detail.

[0059] Step 310: After establishing a connection with the server in the kernel layer, send a communication data request to the server.

[0060] In this embodiment, an HTTPS connection can be established with the server at the kernel layer, and a handshake can be performed with the server.

[0061] After establishing a connection with the server at the kernel level, you can receive the encryption key sent by the server. The encryption key is used to encrypt data during communication with the server.

[0062] In this embodiment, when establishing an HTTPS connection with the server, the client can also specify a server interface address, which is used to receive data during subsequent communication between the client and the server based on the gRPC communication protocol.

[0063] For example, a handshake with the server can be used to implement the full handshake phase over HTTPS.

[0064] For example, if the client terminal uses Windows as its operating system, then the client can establish an HTTPS connection with the server and perform a handshake with the server in the Windows kernel layer.

[0065] Optionally, the communication data request can be transmitted to the server in the form of a data packet. Therefore, before performing step 310, a data packet containing the communication data request can be constructed.

[0066] After receiving the data packet, the server can obtain the communication data request by parsing the data packet.

[0067] For example, the communication data requirements may include requirements for the size of the communication data frame, requirements for the communication protocol standard, etc.

[0068] Each communication data request can be constructed as a separate data packet and sent to the server; alternatively, all communication data requests can be packaged into a single resource data packet and sent to the server.

[0069] This resource data packet can be used to notify the server of the requirements of the GRPC communication protocol for this construction.

[0070] Step 320: Send the parameters required for calling the GRPC communication protocol to the server.

[0071] The parameters required for this calling method can be set by the user as needed before establishing the gRPC communication protocol with the server. Understandably, different use cases require different calling methods from the server, and the content of these required parameters will also differ depending on the required calling method. These parameters are predefined.

[0072] In this embodiment, the parameters required for calling the gRPC communication protocol and the interface address can also be sent to the server. The interface address indicates the communication interface with the server when communicating based on the gRPC communication protocol.

[0073] Step 330: Receive the return value from the server based on the method call, parse the return value, and obtain the return data structure information of the method call of the GPPC communication protocol.

[0074] The return value of this calling method represents the information returned by the server's calling method when communicating based on the GPRC communication protocol. The specific content of this return value can be determined by the user through the agreed-upon parameters returned by the server when calling the server's calling method based on the GPRC communication protocol. Specifically, the content of this return value can be agreed upon according to actual needs. It is worth noting that the agreed-upon return value may differ depending on the usage environment of the GPRC communication protocol and the specific calling method.

[0075] The returned data structure information can be obtained by parsing the return value. This returned data structure information is used to indicate the data structure standard received from the server when communicating with the server based on the gRPC communication protocol.

[0076] When the client and server communicate subsequently based on the GRPC communication protocol, after the client calls the server's calling method, the server returns data in the format agreed upon above for the returned data structure information.

[0077] Through steps 310 to 330 above, the agreement on the communication method based on the GRPC communication protocol can be realized.

[0078] After completing the agreement on the communication method based on the GRPC communication protocol in steps 310 to 330 above, the current data stream can be kept open as needed. With the current data stream open, the client can listen to the push sent by the server, and the client can also continue to call the required remote call method using the current data stream.

[0079] Steps 310 to 330 above can implement the conventions of the gRPC communication protocol at the kernel level, which can enable faster connection with the server, reduce the possibility of being damaged or eavesdropped by other malicious programs, and improve the security and efficiency of communication with the server.

[0080] Depending on actual needs, the communication data requirements involved in step 310 above may include at least the following situations.

[0081] In one implementation, the communication data requirement includes a communication protocol requirement, and the data packet may include a phantom data packet. The phantom data packet is a phantom data packet that satisfies the communication protocol requirement. Step 310 described above may include: constructing a phantom data packet that satisfies the communication protocol requirement and sending the phantom data packet to the server, the phantom data packet indicating the communication protocol used.

[0082] The phantom packet is used to indicate the communication protocol used. For example, the phantom packet is used to inform the server that the current client is using the HTTP protocol standard.

[0083] In this embodiment, the phantom data packet can also be represented as a Magic data packet.

[0084] For example, the current client may be using the HTTP protocol standard HTTP2.

[0085] In another embodiment, the communication data requirement includes a frame size requirement, and the data packet may include a frame setting packet; step 320 above may include: constructing a frame setting packet containing the frame size requirement and sending the frame setting packet to the server.

[0086] This frame settings packet is used to indicate the frame size and frame window size of the data transmitted during communication based on the gRPC communication protocol.

[0087] For example, the frame size and frame window size defined by the frame settings packet can be the frame size and frame window size currently used by the client in the communication.

[0088] In another implementation, the communication data requirement includes the required size of the data stream, and the data packet may include an update window packet. Step 310 above may include: constructing an update window packet containing the data stream size, and sending the update window packet to the server so that the server updates the data stream size of the current connection according to the update window packet.

[0089] By using the above method, the server can be informed of the relevant limitations of data transmission in the GRPC communication protocol through interaction with the server. The relevant limitations of data transmission can be adaptively agreed upon, so that the communication method based on the GRPC communication protocol provided in this embodiment can adapt to more usage scenarios and improve the applicability of the communication method based on the GRPC communication protocol.

[0090] To improve the security of the communication method based on the gRPC communication protocol during the protocol agreement process, the transmitted parameters can be encrypted. Therefore, before step 320, the method may further include: receiving an encryption key sent by the server, which is used to encrypt data during the communication process.

[0091] Step 320 may include: using the encryption key to encrypt the parameters required for calling the GRPC communication protocol method, obtaining encrypted parameters, and sending the encrypted parameters to the server.

[0092] For example, the encryption key mentioned above can be a symmetric encryption key. After receiving the encryption parameters, the server can use the key to decrypt the encryption parameters, and then deserialize the decrypted data to obtain the parameters required by the calling method when communicating based on the gRPC communication protocol.

[0093] For example, the return value obtained from the server can be a cryptographic return value. Step 330 above may include: decrypting the cryptographic return value using the encryption key to obtain the return data structure information of the calling method of the gRPC communication protocol.

[0094] To enable the server to more successfully obtain the parameters required for the client's agreed-upon method call, the parameters and interface address of the gRPC communication protocol transmitted to the server can be serialized before being sent to the server. Therefore, step 320 may include serializing the data structure of the method call parameters and the server interface address to obtain serialized parameters, and then sending these serialized parameters to the server.

[0095] Serialization is the process of converting parameters that need to be transmitted to the server into a form that can be stored or transmitted. Parameters after serialization can be binary data.

[0096] In this embodiment, serialization parameters are sent to the server through an HTTPS connection established with the server.

[0097] In this embodiment, after obtaining the serialization parameter, the server can perform deserialization processing to obtain the parameters required for the calling method agreed upon by the client.

[0098] Optionally, after serialization, the serialization parameters can be encrypted using the aforementioned encryption key, and the encrypted serialization parameters can be sent to the server.

[0099] In this embodiment, after obtaining the serialization parameters of the encrypted state, the server can first perform decryption processing and then deserialization processing to obtain the parameters required for the calling method agreed upon by the client.

[0100] In this embodiment, if the data sent to the server in step 320 is serialized data, then the return value returned by the server to the client can also be a serialized return value. Based on this, step 330 may include: deserializing the return value to obtain the return data structure information of the calling method of the gRPC communication protocol.

[0101] Alternatively, the return value can be obtained by the server through serialization followed by encryption. Based on this, when the client receives the return value, it can first decrypt it and then deserialize it to obtain the parameters required by the client's agreed-upon method call.

[0102] In this embodiment, in order to better track and record the communication process with the server based on the GRPC communication protocol, the method for communication based on the GRPC communication protocol may further include: constructing a data stream identifier.

[0103] In this embodiment, a sequential sequence can be constructed based on the data stream identifier, wherein the sequential sequence is used to record the position of the data stream communicating with the server.

[0104] For example, the initial value of the sequential sequence can be zero, and the sequential sequence can be incremented by one each time the client communicates with the server via the gRPC communication protocol.

[0105] This embodiment provides a method for communication based on the gRPC communication protocol, which can directly perform communication based on the gRPC communication protocol at the kernel level. This allows for more efficient connection with the server while reducing the risk of damage and eavesdropping by other malicious programs, thus greatly improving communication security.

[0106] Based on the same application concept, this application also provides an apparatus for communication based on the GRPC communication protocol, which corresponds to the method for communication based on the GRPC communication protocol. Since the principle of the apparatus in this application is similar to that of the aforementioned method for communication based on the GRPC communication protocol, the implementation of the apparatus in this application can refer to the description in the above-mentioned method embodiments, and the repeated parts will not be described again.
