Description

Technical Field

[0001] The invention belongs to the field of software updating, and in particular relates to a method and device for self-updating management of upper computer client software based on a Qt framework. Background Art

[0002] With the rapid development of the industrial field, the stability and functional integrity of the host client as a bridge connecting users and industrial equipment are crucial, and the application of host client software in industrial control systems is becoming more and more extensive. With the continuous development of computer technology, software updates have become an important means to maintain software functionality and system security. Especially in the Linux system, the update management of the host client software developed based on the Qt framework is crucial to ensure software performance and user experience.

[0003] However, the traditional method of updating the client software of the host computer usually requires users to manually download the software update package and install it. This method is not only inefficient, but also prone to software damage or system crashes due to improper operation, and has problems such as low update efficiency and poor security. Therefore, how to achieve efficient and secure automatic update of the client software of the host computer has become an urgent problem to be solved.

[0004] In the existing technology, although there are some solutions for automatic software updates, most of these solutions are for applications under Windows systems, and are not applicable to the host client software developed based on the Qt framework in the industrial field of Linux systems. The industrial field has higher requirements for the environment, including software version compatibility, hardware and driver and maintenance cycle costs, higher security requirements, and many scenarios require zero crashes. Therefore, it is of great practical significance to develop a self-update management method for host client software developed based on the Qt framework in the industrial field of Linux systems. Summary of the invention

[0005] In order to solve the problems of the above-mentioned prior art, the present invention provides a host computer client software self-update management method and device developed based on the Qt framework, which can automatically detect, download and install the latest version of the software, thereby improving the efficiency and convenience of software maintenance and ensuring the security of security software.

[0006] The present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a method for self-updating and managing client software of a host computer based on a Qt framework, comprising: S1, when the software of the upper computer client needs to be updated, the latest version information file of the software is obtained through the self-update detection thread, and the version information in the version information file is compared with the version information of the local old version software to determine whether the software needs to be updated; if the judgment result is that the software needs to be updated, S2 is executed, and after confirming that the operator's identity is safe, S3 is executed to update the new version, otherwise, the next update detection is waited according to the set update detection time; the version information file contains the version information of the new version of the software; S2, before executing the software update, ensure the operator's identity security and operation security through identity authentication and update authorization authentication; S3, the host computer client downloads the software update package and performs identity authentication, update authorization source verification, integrity verification and version compatibility verification on the software update package, and automatically executes the installation script after the verification passes, decompresses and installs the software update package; S4, set up software update process management, regular check update mechanism and rollback mechanism; S5, after the software update package is installed, the host computer client automatically restarts and loads the new version of the software to complete the self-update process; S6, set up breakpoint resume, grayscale release, and A / B testing.

[0007] Furthermore, when the software of the host computer client needs to be updated, the latest version information file of the software is obtained through the self-update detection thread, including: The software of the host computer client sends an update request to the server when it is started or periodically, and receives the latest version information file of the software sent by the server based on the update request. The update request is used to trigger the server to send the latest version information file of the software to the host computer client.

[0008] Furthermore, the host computer client downloads the software update package of the new version software through the HTTPS protocol.

[0009] Furthermore, in S2, the operator needs to be authenticated and authorized. The authentication is done by digitally signing the software update package, which is digitally signed by a trusted developer or software provider. When executing the update, the host client verifies the digital signature of the software update package to ensure that the software update package has not been tampered with. The public key infrastructure system is used to manage the signing key to ensure that only the service provider with a valid private key signs the software update package, and requires users to perform multi-factor authentication when performing software updates; In S3, the update authorization source verification is specifically as follows: verifying the digital signature of the software update package; the integrity verification is specifically as follows: after the operator's identity is confirmed and authorized, the software update package is transmitted using an encryption protocol, and HPKP technology is used to prevent man-in-the-middle attacks. The software update package uses hash verification to verify the integrity of the downloaded software update package. After downloading the software update package, the client compares the hash value of the software update package with the hash value provided by the server to ensure that the software update package has not been tampered with, and stores the hash value of the software update package on a trusted server and compares it during update. At the same time, the software update package is digitally signed. After receiving the software update package, the upper computer client first verifies the legitimacy of the signature.

[0010] Furthermore, S4 specifically: supports checking for updates. The host client periodically queries the server for new updated versions. It adopts version control and incremental updates, sets a regular update check mechanism, and supports manually triggered update checks. It provides an automatic update option. Users choose to let the host client automatically download and install updates to ensure that the user system always uses the latest version; provides a manual update option to allow users to update as needed. In sensitive production environments, administrators control the update time; update notification and rollback mechanism. Before updating, the host client notifies the user of the update content and update size; the user chooses whether to install the update immediately or delay the update; provides a rollback mechanism. If the new version has problems or is unstable, the host client automatically or manually rolls back to the previous stable version.

[0011] Furthermore, in S5, trusted boot in trusted hardware ensures that the system loads trusted operating systems and update programs from the start-up phase to prevent malware from loading and tampering with update files before the update, and ensures that the signatures of the operating system and update programs are verified and can only be loaded with trusted certificates. Provide code integrity protection; place the update process in a controlled sandbox environment to limit the impact of the update process on other parts of the system; provide code signing to ensure that all client codes, including the updater itself, are signed, and unauthorized code cannot run during the update process.

[0012] Furthermore, during the execution of S1, S2 and S3, trusted verification of the installation environment and trusted installation isolation are performed, and trusted audit logs and real-time alarms are generated.

[0013] In a second aspect, the present invention provides a host computer client software self-update management system based on the Qt framework, comprising: The update detection module is used to obtain the latest version information file of the software through the self-update detection thread when the software of the upper computer client needs to be updated, compare the version information in the version information file with the version information of the local old version software, and determine whether the software needs to be updated; if the judgment result is that the software needs to be updated, after confirming the operator's identity security, the new version is updated, otherwise, the next update detection is waited according to the set update detection time; the version information file contains the version information of the new version software; The authentication and authorization module is used to ensure the operator's identity security and operation security through identity authentication and update authorization authentication before executing the software update; The trusted installation module is used to download the software update package and perform identity authentication, update authorization source verification, integrity verification and version compatibility verification on the software update package, and automatically execute the installation script after the verification is passed to decompress and install the software update package; after the software update package is installed, the host computer client automatically restarts and loads the new version of the software to complete the self-update process.

[0014] In a third aspect, the present invention provides a computer device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the upper computer client software self-update management method based on the Qt framework as described above are implemented.

[0015] In a fourth aspect, the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the host computer client software self-update management method based on the Qt framework as described above are implemented.

Changes or adjustments in their relative relationships should also be regarded as the scope of the present invention without substantially changing the technical content.

[0022] See also Figure 1 The present invention provides a method for self-updating the client software of a host computer based on the Qt framework, comprising: S1, when the software of the upper computer client needs to be updated, the latest version information file of the software is obtained through the self-update detection thread, and the version information in the version information file is compared with the version information of the local old version software to determine whether the software needs to be updated; if the judgment result is that the software needs to be updated, S2 is executed, and after confirming that the operator's identity is safe, S3 is executed to update the new version, otherwise, the next update detection is waited according to the set update detection time; the version information file contains the version information of the new version of the software; S2, before executing the software update, ensure the operator's identity security and operation security through identity authentication and update authorization authentication; S3, the host computer client downloads the software update package and performs identity authentication, update authorization source verification, integrity verification and version compatibility verification on the software update package, and automatically executes the installation script after the verification passes, decompresses and installs the software update package; S4, set up software update process management, regular check update mechanism and rollback mechanism; S5, after the software update package is installed, the host computer client automatically restarts and loads the new version of the software to complete the self-update process; S6, set up breakpoint resume, grayscale release, and A / B testing.

[0023] In this implementation, after the host computer client is turned on, it obtains the latest version information file through the self-update detection thread, compares the version information in the version information file with the version information of the local old version of the software, and determines whether the software needs to be updated; if the judgment result is that the software needs to be updated, S2 is executed to authenticate the identity and authorize the updater, and after authorization, S3 is performed to perform security detection on the software update package, otherwise, the next update detection is waited according to the set update detection time; the version information file contains the version information of the new version of the software; Authentication ensures that only legitimate users or services can perform software update operations, preventing unauthorized users from tampering with the system or installing malware. The update user provides credentials, such as username and password, hardware key, dynamic verification code, etc. Multi-factor authentication can also be used to increase the verification level to ensure the authenticity of the identity. For example, in addition to the password, a dynamic verification code or biometric authentication fingerprint, facial recognition, etc. is required. This multi-level verification method can effectively improve the security of authentication and prevent a single verification method from being attacked. Use Transport Layer Security (TLS) / Secure Sockets Layer (SSL) certificates through device / service authentication: Through the SSL / TLS handshake of the communicating parties (client and update server), the identities of each other are verified and data transmission is encrypted. Certificate verification: The client and server use X.509 certificates for authentication to ensure that both parties are trustworthy. Signed through public key infrastructure, the client verifies the signature of the software update package when downloading the update to ensure that the package comes from a trusted developer. Trusted Hardware Security Module Verification Use hardware security modules in sensitive operations (such as certificate generation, private key storage, etc.) to strengthen key management and verification to prevent private key leakage. Through role and permission management, different update permissions can be defined and customized according to different user roles such as administrators, ordinary users, and external suppliers.

[0024] In order to ensure that the software update package has not been tampered with or damaged during the download, storage or transmission process, the upper computer client must verify the integrity of the software update package and generate a hash value through hash value verification. When releasing the software update package, calculate the hash value of the software update package (such as using the Secure Hash Algorithm (SHA)-256 or SHA-512), publish the calculated hash value together with the software update package, and put it in a safe location. Download the hash value verification through the trusted management platform: When downloading the software update package, the client calculates the hash value of the software update package, and compares the hash value provided by the client and the server. If the two are consistent, it means that the package has not been tampered with. If the hash values ​​do not match, the client stops updating and generates an alarm to generate a trusted audit log.

[0025] After the software update package is installed, the host client automatically restarts and loads the new version of the software to complete the self-update process. After verification, the transmission of the software update package will be encrypted. The transmission of the software update package must be protected by the encryption protocol HyperText Transfer Protocol Secure (HTTPS) (TLS / SSL) to prevent data from being tampered with or stolen during transmission. The encrypted connection between the client and the server should use a strong encryption algorithm and certificate to ensure communication security.

[0026] Furthermore, when the software of the host computer client needs to be updated, the latest version information file of the software is obtained through the self-update detection thread, including: The software of the host computer client sends an update request to the server when it is started or periodically, and receives the latest version information file of the software sent by the server based on the update request. The update request is used to trigger the server to send the latest version information file of the software to the host computer client.

[0027] Furthermore, the host computer client downloads the software update package of the new version software through the HTTPS protocol.

[0028] Furthermore, in S2, the operator needs to be authenticated and authorized. The authentication is done by digitally signing the software update package by a trusted developer or software provider. When the client executes the update, it verifies the digital signature of the software update package to ensure that the software update package has not been tampered with. The public key infrastructure system is used to manage the signing key to ensure that only the service provider with a valid private key signs the software update package, and requires the user to perform multi-factor authentication when performing software updates; In S3, the update authorization source verification is specifically as follows: verifying the digital signature of the software update package; the integrity verification is specifically as follows: after the operator's identity is confirmed and authorized, the software update package is transmitted using an encryption protocol, and HPKP technology is used to prevent man-in-the-middle attacks. The software update package uses hash verification to verify the integrity of the downloaded software update package. After downloading the software update package, the client compares the hash value of the software update package with the hash value provided by the server to ensure that the software update package has not been tampered with, and stores the hash value of the software update package on a trusted server and compares it during update. At the same time, the software update package is digitally signed. After receiving the software update package, the upper computer client first verifies the legitimacy of the signature.

[0029] Furthermore, S4 specifically: supports checking for updates, the client periodically queries the server for new updated versions, adopts version control and incremental updates, sets a regular checking mechanism, and supports manually triggered update checks, provides an automatic update option, and users choose to let the client automatically download and install updates to ensure that the user's system always uses the latest version; provides a manual update option to allow users to update as needed, and in sensitive production environments, administrators control the update time; update notification and rollback mechanism, before updating, the client notifies the user of the update content and update size; the user chooses whether to install the update immediately or delay the update; provides a rollback mechanism, if the new version has problems or is unstable, the client automatically or manually rolls back to the previous stable version.

[0030] Furthermore, in S5, trusted boot in trusted hardware ensures that the system loads trusted operating systems and update programs from the start-up phase to prevent malware from loading and tampering with update files before the update, and ensures that the signatures of the operating system and update programs are verified and can only be loaded with trusted certificates. Provide code integrity protection; place the update process in a controlled sandbox environment to limit the impact of the update process on other parts of the system; provide code signing to ensure that all client codes, including the updater itself, are signed, and unauthorized code cannot run during the update process.

[0031] Furthermore, during the execution of S1, S2 and S3, trusted verification of the installation environment and trusted installation isolation are performed, and trusted audit logs and real-time alarms are generated.

[0032] After the host computer client of the present invention is turned on, it obtains the latest version information file through the self-update detection thread, specifically: The host computer client software sends an update request to the server when it is started or regularly. The update request triggers the server to send the latest version information file to the host computer client, and the host computer client software receives the latest version information file sent by the server.

[0033] In some specific implementations, the version information of the present invention includes version number, release time and update content.

[0034] In some specific implementations, the identity authentication and source authentication of the present invention verifies the legitimacy of the software update package through digital signature and Public Key Infrastructure (PKI).

[0035] In some specific implementations, the present invention downloads the software update package of the new version of the software through the HTTPS protocol to ensure the security of data transmission.

[0036] The integrity verification described in the present invention specifically includes: performing digital signature verification and hash value verification.

[0037] After the software update package is downloaded, the present invention verifies the digital signature of the software update package, and the installation operation can be performed only after the verification is successful. The digital signature is generated by the server and added to the software update package. The digital signature of the software update package is an important means to ensure that the software update package maintains integrity and authenticity during transmission and installation. The digital signature can verify the source of the software update package and ensure that it is released by a trusted developer or organization; through the digital signature, it can be ensured that the software update package has not been tampered with or damaged during transmission.

[0038] In some specific implementations, after the software update package is downloaded, a hash value of the software update package is obtained, and the hash value is compared with a checksum value of the software update package to determine the integrity of the software update package. If the software update package is complete, it is installed, otherwise it is not installed.

[0039] Before releasing the software update package, the server will use a specific hash algorithm (such as Message-Digest Algorithm 5 (MD5), SHA-1, SHA-256, etc.) to perform hash calculation on the content of the software update package to generate a checksum of fixed length. This checksum will be recorded in the release information for users to verify when downloading.

[0040] After the user downloads the software update package, the same hash algorithm is used to perform hash calculation on the downloaded software update package to obtain a new checksum. This newly generated checksum is compared with the checksum provided by the server. If the two are consistent, it means that the software update package is complete and has not been tampered with; if they are inconsistent, it means that there may be a problem and it is necessary to re-download or contact the server for confirmation.

[0041] Example 1 like Figure 2 As shown, the present invention is based on the Qt framework of the host computer client software self-update management method, the method comprises the following steps: (1) The server releases the software update package The server administrator packages the compiled new version of the software into a software update package and uploads it to the designated directory of the server; the server generates a version information file of the new version of the software, including the version number, release time, update content, and provides a download link.

[0042] (2) PC client software detection and update The upper computer client software sends an update request to the server when it is started or regularly. The update request triggers the server to send the latest version information file to the upper computer client, and the upper computer client software receives the latest version information file sent by the server.

[0043] The upper computer client compares the version number in the received version information file with the version number of the local old version software to determine whether an update is needed; if the two version numbers are the same, no update is required; if the two version numbers are different, an update is required.

[0044] (3) The host client downloads the software update package If the judgment result is that an update is required, the host client automatically downloads the software update package from the server to the local temporary directory according to the download link provided by the server. To ensure that the software update package is not tampered with during transmission, the software update package is downloaded through the HTTPS protocol to ensure the security of data transmission.

[0045] During the download process, the host client will display the download progress and status so that users can understand the download progress.

[0046] (4) Install the software update package on the host client It should be noted that the downloaded software update package needs to be verified for source, integrity, and version compatibility.

[0047] The specific process is: 1) Source verification: Verify the digital signature of the software update package. Subsequent operations can only be performed after successful verification to ensure that the software update package comes from a trusted source.

[0048] 2) Integrity verification of software update packages: Use hash functions to verify software update packages to ensure that the downloaded software update packages have not been tampered with. Trusted computing platforms (such as TPMs) can store public keys to verify the integrity of software update packages before installing them.

[0049] During the specific operation, a hash algorithm (such as md5 or sha256) is used to calculate the hash value, and the calculated hash value is compared with the check value provided by the server. If the two are consistent, the software update package is complete and the next step is performed; otherwise, the software update package is incomplete and the next step is not performed. The integrity of the software update package is ensured by verifying the check value.

[0050] 3) Version control and verification: Before installing a software update package, the system can check the compatibility between the local old version of the software and the new version of the software to be installed through a trusted computing mechanism. This can prevent incompatible or potentially harmful updates from being applied.

[0051] After the software update package is verified, the host computer client automatically executes the installation script to decompress and install the software update package (decompress the software update package to obtain the files of the new version of the software and replace the original files of the old version of the software).

[0052] The atomicity of the software update package installation process must be guaranteed, either all of it is executed or not at all, with no intermediate state. A separate script or tool is used to ensure atomicity, and a detailed design of multi-layer protection is carried out.

[0053] During the installation of the software update package, the host computer client will back up the files of the old version of the software so that a rollback operation can be performed when the software update package fails to be installed, that is, it can be restored by restoring the backup. The present invention designs an effective rollback mechanism to deal with update failures or incompatibility. Trusted computing can ensure data integrity and system stability during the rollback process.

[0054] After the software update package is installed, the upper computer client software sends an update request again and receives the latest version information file sent by the server; the version number in the received version information file is compared with the version number of the local old version software. If the two version numbers are the same, the update is successful. If the two version numbers are different, the update is unsuccessful and needs to be updated again.

[0055] After the software update package is installed, if the new version of the software requires migrating user data, the installer will prompt the user to migrate the data.

[0056] (5) The host computer client is updated After the software update package is installed, the host client automatically restarts and loads the new version of the software to complete the self-update process.

[0057] After the host computer client is restarted, it will perform simple initialization operations to ensure that the new version of the software can run normally.

[0058] At each stage of the above-mentioned update process of the present invention, trusted verification of the installation environment and trusted installation isolation are performed, and a trusted audit log is generated. The specific operations include: 1) Secure Boot and Chain of Trust: At each stage of the update process, Secure Boot and Chain of Trust mechanisms are used to ensure that each step is performed in a trusted environment. This means that the decompression and installation of the software update package must be completed in a verified and trusted environment.

[0059] 2) Dynamic trust evaluation: During the update process, the trust status of the current operating environment can be dynamically evaluated to ensure that no update operations are performed in an unsafe environment; file trust static evaluation, the evaluation data source is reliable, which can be achieved by real-time monitoring of the system status and configuration.

[0060] 3) Audit and recording mechanism: Record and audit all operations during the update process to ensure that the source, version, and execution status of each update can be traced. This is very important for subsequent security analysis and troubleshooting.

[0061] Example 2 When performing software updates in a production environment, the specific process is as follows: (1) Backup Before updating, use a script or tool to back up the files of the old version of the software so that you can restore the original functionality of the program in case the update fails.

[0062] (2) Preparation Before updating, ensure the correctness of the environment, such as checking the system version, disk space, etc.

[0063] (3) Download the software update package The upper computer client software periodically sends an update request to the server, and the update request triggers the server to send the latest version information file to the upper computer client, and the upper computer client software receives the latest version information file sent by the server.

[0064] The upper computer client compares the version number in the received version information file with the version number of the local old version software to determine whether an update is needed; if the two version numbers are the same, no update is required; if the two version numbers are different, an update is required.

[0065] If the result of the judgment is that an update is required, the host computer client automatically downloads the software update package from the server to the local temporary directory according to the download link provided by the server.

[0066] (4) Check for software update packages The digital signature of the software update package is verified. The installation operation can be performed only after successful verification to ensure that the software update package comes from a trusted source. The downloaded software update package uses a hash algorithm (such as md5 or sha256) to calculate the hash value, and the calculated hash value is compared with the checksum provided by the server. If the two are consistent, the software update package is complete and the next step of installation is performed; otherwise, the software update package is incomplete and the next step of installation is not performed.

[0067] At the same time, version compatibility verification is also performed to check the compatibility between the local old version software and the new version software to be installed.

[0068] (5) Stop the program Stop the program that is running the old version of the software to prepare for the update. That is, before updating the program, stop the program first to ensure that the update process will not be interrupted.

[0069] (6) Replace files Replace the original files of the old version of the software to install the software update package.

[0070] (7) Start the program Launch the new version of the software to verify that it works properly.

[0071] (8) Inspection procedures After the update, check the integrity and functionality of the program to ensure that the update was successful. Specifically, use a script or tool to check the correctness of the program of the new version of the software to ensure that it has been successfully updated.

[0072] (9) Restore backup If the update fails, restore the backed-up files of the original old version of the software to restore the original functions of the program, effectively solving the problem of restoring program functions after an update failure due to unexpected circumstances when updating the program in a production environment.

[0073] The self-update management method of the present invention has significant advantages in terms of user experience. First, users do not need to manually download and install software update packages, which reduces the user's operation steps and waiting time. Second, during the automatic update process, the client will display the update progress and status in real time, allowing users to clearly understand the update process (silent installation can also be selected). In addition, after the installation is completed, the new version of the software is automatically restarted and loaded, without the user having to perform additional operations, further improving the user experience.
