[0026] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0028] The remote debugging method, system, and computer storage medium provided in the embodiments of this application will be described exemplarily below with reference to the accompanying drawings.

[0029] Figure 1 This is a flowchart illustrating the remote debugging method provided in an embodiment of this application. Figure 1 As shown, the remote debugging method 100 is used to debug an interactive display all-in-one machine, and the remote debugging method 100 includes the following steps:

[0030] S101. Establish a first connection with the remote control server based on the first security protocol through the remote debugging equipment.

[0031] Specifically, the remote debugging device can establish a first connection with the remote control server through a communication mechanism. This first connection can be based on a preset first security protocol. The first security protocol, for example, can be encryption technology to ensure the confidentiality, integrity, and non-repudiation of data during transmission. Through this first connection, the remote debugging device can securely communicate with the remote control server, providing a reliable foundation for subsequent debugging operations.

[0032] The first connection is a communication link established between the remote debugging device and the remote control server. This first connection can be implemented based on a first security protocol, primarily ensuring secure and reliable data transmission between the remote debugging device and the remote control server.

[0033] For example, the remote debugging device can be deployed at an external customer site or internal testing environment, connecting to the interactive display all-in-one machine to be debugged. The remote debugging device can provide hardware-level control and data interaction. The remote control server can be deployed in the cloud, responsible for managing all RDDs, ITIPs, Android application clients, and client connections, authentication, command forwarding, and status monitoring.

[0034] It is understood that the above description of the remote debugging device, the remote control server, and the establishment of the first connection based on the first security protocol is merely exemplary. Those skilled in the art can select and configure the remote debugging device, the remote control server, and the establishment of the first connection based on the first security protocol according to actual needs, as long as the technical principles of this application can be achieved.

[0035] In some embodiments, establishing a first connection based on a first security protocol includes: the remote debugging device can establish a multiplexed, forward error-corrected, and / or encrypted connection of a predetermined duration with the remote control server through the first security protocol.

[0036] Specifically, the connection established between the remote debugging equipment and the remote control server is a secure communication link. This initial connection satisfies the data transmission requirements during remote debugging, ensuring the smooth operation of the debugging process.

[0037] For example, the first connection may support multiplexing, allowing multiple data streams to be transmitted simultaneously in the communication link. For instance, it may simultaneously transmit device status information, commands, log data, and real-time feedback information. Multiplexing, by adding specific identifiers to data packets, enables different data streams to be accurately distinguished and processed within the same link.

[0038] The first connection may also feature forward error correction. Forward error correction adds redundant information at the sending end, allowing the receiving end to automatically detect and correct errors that may occur during transmission without requesting retransmission. Forward error correction is suitable for unstable network environments or situations with high latency, effectively reducing the risk of data transmission interruption. Even if some data is lost or corrupted during transmission, the receiving end can still recover the original data using the redundant information, thus ensuring data integrity and accuracy.

[0039] The first connection can also employ encryption algorithms to encrypt the transmitted data. Encryption ensures the confidentiality and integrity of data during transmission. By using encryption algorithms, all data transmitted between the remote debugging device and the remote control server is converted into ciphertext that cannot be deciphered by unauthorized third parties. Only the recipient with the correct decryption key can decrypt and read the data content. This encryption mechanism not only protects the sensitive information of the interactive display all-in-one machine, such as device configuration parameters, user data, and instructions, but also prevents data from being tampered with or stolen during transmission.

[0040] For example, the first connection can employ either a symmetric or asymmetric encryption algorithms, such as AES-GCM (Advanced Encryption Standard - Galois / Counter Mode) or ChaCha20-Poly1305 symmetric encryption algorithms. The session key is used to encrypt the transmitted raw data (plaintext), converting it into garbled text (ciphertext). The GCM mode or Poly1305 message authentication code generates an authentication tag for each data packet. The receiver verifies this tag using the same key. If the data is tampered with in any way during transmission, the verification fails, and the connection is immediately terminated, thus avoiding the risk of malicious data tampering (such as changing a "reboot" command to "format").

[0041] A pre-set duration connection is the valid duration (e.g., 20 minutes) set when the connection is established. During this period, the connection remains active, allowing continuous data transmission and interaction. The pre-set duration can be adjusted according to the specific debugging task. For example, a shorter connection duration can be set for simple debugging operations, while a longer connection duration can be set for complex debugging that requires a long time. Setting a pre-set duration can prevent long-term idle connections from consuming excessive resources.

[0042] It is understood that the above description of the predetermined duration is merely exemplary, and those skilled in the art can select and set it according to the technical principles described in this application, as long as the technical principles of this application can be implemented.

[0043] In some embodiments, the first security protocol includes the UDP-based QUIC protocol.

[0044] Specifically, the QUIC protocol (Fast UDP Internet Connection Protocol) can be implemented based on UDP (User Datagram Protocol), meaning that additional mechanisms can be introduced to compensate for UDP's shortcomings in reliability. UDP is a connectionless, lightweight transport protocol characterized by low latency and high throughput, but it does not guarantee reliable data transmission. The QUIC protocol, by implementing reliability mechanisms similar to TCP (Transmission Control Protocol) on UDP, such as packet retransmission and congestion control, while retaining UDP's low latency advantage, achieves a balance between transmission efficiency and reliability, thus meeting the dual requirements of real-time performance and reliability in remote debugging.

[0045] S102. Establish a second connection with the remote control server based on the second security protocol through the client.

[0046] Specifically, communication between the client (such as a web interface used for operations or development) and the remote control server can be achieved through a second connection based on a second security protocol. The second connection is a secure, reliable, and efficient communication link established between the client and the remote control server, implemented through a second security protocol. This second security protocol not only ensures secure and accurate data transmission between the client and the remote control server but also guarantees data integrity and confidentiality during remote debugging.

[0047] The second connection can ensure that all sent data is correctly received through mechanisms such as sequence numbers, acknowledgments (ACKs), and retransmissions. It can also guarantee accurate data transmission even under poor network conditions.

[0048] The second connection can be achieved by encrypting the communication link, for example, through encryption methods. All data transmitted between the client and the remote control server is encrypted to ensure the confidentiality and integrity of the data during transmission. Encryption algorithms can, for example, include a combination of symmetric and asymmetric encryption to achieve data encryption and secure key exchange.

[0049] It is understandable that the first connection and the second connection use the same encryption algorithm level. That is, if the first connection uses a specific encryption algorithm such as AES-GCM or ChaCha20-Poly1305, then the second connection must also use the same type of algorithm or one with equivalent cryptographic strength, so as to avoid differences in encryption strategies between different connections.

[0050] In some embodiments, establishing a second connection based on a second security protocol may include:

[0051] The client establishes a full-duplex communication connection with the remote control server based on the second security protocol.

[0052] Specifically, a full-duplex communication connection refers to a connection method in a communication system where data can be transmitted simultaneously in both directions. A full-duplex communication connection allows data to be sent and received at the same time, without waiting for the other party to complete the sending or receiving process.

[0053] For example, the client and the remote control server negotiate a protocol to determine the specific version and parameters of the second security protocol to be used. The two parties then perform a security handshake, including key exchange and authentication steps. After the security handshake is completed, the two parties formally establish a full-duplex communication connection and begin data transmission.

[0054] For example, the second security protocol may include a TLS-based WebSocket protocol.

[0055] Specifically, TLS (Transport Layer Security) is a security protocol used to provide encryption, authentication, and data integrity protection in network communications. For example, TLS can encrypt all data transmitted between a client and a remote control server using encryption algorithms such as AES, ensuring that data is not stolen or tampered with during transmission. TLS can also use digital certificates to authenticate both communicating parties. When establishing a connection, the client and remote control server verify each other's certificates to ensure that both parties are legitimate and trustworthy, thus preventing man-in-the-middle attacks.

[0056] The WebSocket protocol is a full-duplex communication protocol based on TCP, allowing clients and servers to establish persistent, bidirectional communication channels. This enables clients and remote control servers to send and receive data in real time. WebSocket reduces data transmission latency, ensuring smooth remote debugging. By combining TLS with WebSocket, the second connection not only inherits the real-time and low-latency characteristics of WebSocket but also provides security protection through TLS, thus ensuring secure and efficient communication between the client and the remote control server.

[0057] S103. In the remote control server, the identity of the client is authenticated, and after successful authentication, a debugging session is established between the designated client and the designated remote debugging device; wherein, in the debugging session, the remote control server receives instructions from the client and forwards the instructions to the remote debugging device through the first connection, the instructions being used to control the remote debugging device to perform operations on the interactive display all-in-one machine; the remote control server receives data collected from the interactive display all-in-one machine by the remote debugging device and forwards the data to the client through the second connection.

[0058] Specifically, when a client requests to establish a connection with the remote control server, the remote control server performs authentication to ensure that the client is a legitimate and authorized client. After completing the authentication and confirming the client's legitimacy and authorization status, the remote control server creates and initializes a dedicated debugging session between the client and the specific remote debugging device. This process involves assigning a unique session identifier and configuring relevant session parameters, such as data transmission format and timeout settings, to ensure the smooth operation of the debugging process.

[0059] During a debugging session, the remote control server receives instructions from the client. These instructions are used to control the remote debugging device to perform operations on the interactive display all-in-one machine being debugged, such as querying device status, modifying device parameters, or performing software updates. Upon receiving the instructions, the remote control server processes and verifies them. It checks whether the format and content of the instructions conform to predefined protocol specifications, ensuring the legality and completeness of the instructions. The remote control server can also parse the instructions, extracting key operational information and parameters to accurately forward them to the remote debugging device.

[0060] During remote debugging, the remote control server receives data from the interactive display all-in-one machine collected by the remote debugging device. This data may include, for example, device status, performance indicators, or fault information. After verifying, formatting, and / or securely encapsulating the data, the remote control server forwards the data to the client via a second connection based on a second security protocol. Upon receiving the data, the client can perform fault analysis on the interactive display all-in-one machine.

[0061] In some embodiments, during the debugging session, instructions and / or data transmitted via the first connection and the second connection are end-to-end encrypted.

[0062] Specifically, during the debugging session, to ensure communication security and data confidentiality, all instructions and / or data transmitted through the first and second connections can also employ end-to-end encryption. Specifically, instructions sent from the client are encrypted before transmission, and only the designated remote debugging device can decrypt and execute these instructions. Similarly, data collected by the remote debugging device from the interactive display all-in-one machine is also encrypted before transmission, and only the corresponding client can decrypt and view this data. This encryption method prevents data from being stolen or tampered with by intermediate nodes, ensuring that even if data passes through multiple network nodes during transmission, only the two ends of the communication can read the data. Understandably, in end-to-end encrypted remote debugging, the remote control server cannot access the encrypted communication content and is primarily used to establish and maintain secure communication channels, support key exchange and authentication, and perform functions such as data relay and flow control.

[0063] For example, at the initial stage of establishing a debug session, the client and the remote debug device can use a key exchange protocol, such as ECDH (Elliptic Curve Diffie-Hellman Key Exchange), to set a session key over an insecure channel. At this time, the remote control server is only responsible for transmitting exchange messages but cannot calculate the session key. Before sending a command, the client uses this session key and a preset encryption algorithm (such as XChaCha20-Poly1305) to encrypt the application layer data of the command. Upon receiving the command, the remote debug device decrypts it using the same session key.

[0064] In some embodiments, after establishing a debugging session, the remote debugging method may further include: the remote control server verifying whether the client has permission to access the specified remote debugging device; the remote control server sending a session establishment notification to the remote debugging device and receiving confirmation information from the remote debugging device.

[0065] Specifically, after establishing a debugging session, the remote control server verifies whether the client has permission to access the specified remote debugging device by querying an access control list or other authorization mechanisms. Upon successful verification, the remote control server sends a session establishment notification to the remote debugging device. After completing initialization, the remote debugging device sends an acknowledgment to the server. The remote control server verifies the received acknowledgment to ensure its authenticity and completeness.

[0066] In some embodiments, the remote debugging method may further include: recording session logs through the remote control server, wherein the session logs include at least the session initiator, the target device, the session time, and / or the type of instruction executed.

[0067] Specifically, the remote debugging method may also include session logs recorded by a remote control server. The session logs include at least the identity information of the session initiator, the detailed identifier of the target device (such as an interactive display all-in-one machine), the specific time of the session (including start, end and duration), and / or the type and content of the instructions executed during the debugging process, so that problems can be quickly located or faults can be troubleshooted during the debugging process.

[0068] In summary, the remote debugging method 100 provided in this application embodiment achieves secure communication between the remote debugging device and the remote control server, as well as between the client and the remote control server, through a connection based on a first security protocol and a second security protocol. Simultaneously, the client's identity is authenticated on the remote control server, ensuring the security and reliability of the debugging process. Furthermore, the remote debugging method can establish a debugging session between the client and a designated remote debugging device, enabling the client to remotely send commands to debug the interactive display all-in-one machine, thereby improving debugging efficiency and reducing maintenance costs.

[0069] Based on the same inventive concept, this application also provides a remote debugging system 200. Figure 2 This is a schematic diagram of the structure of the remote debugging system provided in an embodiment of this application. Figure 2As shown, the remote debugging system 200 includes: a remote debugging device, a client, and a remote control server; wherein, the remote debugging device is configured to establish a first connection with the remote control server based on a first security protocol through a first secure communication module, and receive instructions from the remote control server and / or send data to the remote control server through the first connection; the client is configured to establish a second connection with the remote control server based on a second security protocol through a second secure communication module, and send the instructions to the remote control server and / or receive data from the remote control server through the second connection; the remote control server is configured to establish communication connections with multiple remote debugging devices and multiple clients, perform identity authentication and permission verification on the clients, establish a debugging session between the verified clients and the authorized remote debugging devices, and forward encrypted instructions and / or data in the established debugging session.

[0070] Specifically, the remote debugging device can establish a first connection with the remote control server based on a first security protocol through its built-in first secure communication module. This first connection can support end-to-end encryption, multiplexing, and / or forward error correction to ensure the security and reliability of data transmission. Through this first connection, the remote debugging device can receive instructions from the remote control server and execute corresponding operations, while simultaneously sending the collected data from the interactive display all-in-one machine back to the remote control server.

[0071] Remote debugging equipment can communicate with a remote control server through multiple modules. For example... Figure 2 As shown, the remote debugging device may include, for example, a control module, a log acquisition module, an information acquisition module, and a signal source module. These modules are responsible for executing commands sent by the client, acquiring information and data from the interactive display all-in-one machine, and sending the information and data back to the remote control server. The remote debugging device may include, for example, one or more interfaces, such as HDMI, Type-C, etc., for connecting external signal sources and the interactive display all-in-one machine.

[0072] The client can establish a second connection with the remote control server based on a second security protocol, for example, through a second secure communication module. Through this second connection, the client can send debugging commands to the remote control server and receive data from the interactive display all-in-one machine forwarded by the remote control server. The client can be, for example, a computer, mobile phone, or tablet.

[0073] The remote control server can be configured to establish communication connections with multiple remote debugging devices and / or multiple clients. The remote control server is the core component of the remote debugging system, used to manage and coordinate communication between clients and remote debugging devices. The remote control server can receive instructions from clients through its network module, perform client authentication and permission verification, ensuring that only authorized clients can establish debugging sessions with specific remote debugging devices.

[0074] During a debugging session, the remote control server can forward client commands to the corresponding remote debugging device. Simultaneously, the remote control server can also receive data collected from the interactive display unit by the remote debugging device and forward that data to the client.

[0075] In one embodiment, the remote debugging device may further include: an input simulation module, which is used to inject HID input events into the interactive display all-in-one machine according to instructions.

[0076] Specifically, the input simulation module can inject HID (Human Machine Interface) input events, such as button presses, touches, or swipes, into the interactive display all-in-one machine based on instructions sent by the client, and then inject these events into the machine. The input simulation module can support various types of HID input events, thereby simulating various input scenarios encountered by the interactive display all-in-one machine.
