Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to ensure information security, prevent information leakage of each process node in the use of a document and conform to the localization trend of a secret-related user, an electronic document protection technology is designed, and automatic forced encryption is guaranteed to be carried out at the end of the document in the whole operation period process of the document.
In order to support the automatic forced encryption processing of editable electronic documents under the domestic operating system, the following problems need to be solved:
the method solves the problem of how to automatically and forcibly encrypt, and accurately identifies the closed document operation window of the user operating the Jinshan WPS software, the Yongzhong Office software and the text editor (the Pluma software under the winning bid kylin system and the Yin river kylin system and the gedit software under the Zhongkoidyu system) and forcibly and actively encrypts the document when the user closes the document operation window after the user operates the document Office software by using the Office software on the premise that the document Office software of the existing Jinshan WPS software, the Yongzhong Office software and the text editor software is not modified.
The method solves the fundamental problems that how to correspondingly adapt and support different Office software in a domestic operating system, the realization of each software has larger difference, for example, Jinshan WPS software is realized by adopting Qt development, Yongzhong Office software is realized by adopting java, a pluma editor and a gedit editor are developed by adopting gtk, and the identification of closing of the window of the Office document of each software and the identification of the opened document are problems.
The embodiment of the invention provides an electronic document encryption method for a domestic operating system, which comprises the following steps of:
110, for different types of character editing software under a domestic operating system, injecting the character editing software by adopting a hook technology;

The injection of the hook technology into the text editing software also binds the hook technology with the text editing software, namely the hook technology is bound with the operation of a document opened in the text editing software.
For Windows systems, the hook technology is based on an event-driven mechanism, and it is said that the whole system is implemented by message passing. hook is a special message handling mechanism that monitors various event messages in a system or process, intercepts messages destined for a target window, and handles them. Therefore, the hook can be customized in the system to monitor the occurrence of specific events in the system, and perform specific functions, such as screen word extraction, log monitoring, keyboard interception, mouse input and the like.
The hook is of various types, each hook can intercept corresponding messages, for example, a keyboard hook can intercept keyboard messages, a shell hook can intercept, start and close messages of an application program, and the like. Hooks can be divided into thread hooks, which can monitor event messages for a given thread, and system hooks, which monitor event messages for all threads in the system. Because system hooks affect all applications in the system, the hook functions must be placed in separate Dynamic Link Libraries (DLLs).
Therefore, hook is an interception mechanism of Windows messages, and can intercept messages of a single process (thread hook), messages of all processes (system hook), and perform customized processing on the intercepted messages. The Windows message carries information useful for some programs, such as Mouse type information, window handle information, Mouse position information and the like, and the screen word-taking function of the Jinshan word-taking device can be performed by intercepting the messages.
120, monitoring the operation of the windows corresponding to all the documents in the text editing software by combining one of an X11 graphical interface development technology, a gtk graphical interface development technology and a JNI technology according to the type of the text editing software;
different types of character editing software are developed by different development programs, namely C + + and java, and the underlying programs of different development software are different, so that one of an X11 graphical interface development technology, a gtk graphical interface development technology and a JNI technology is selected to monitor the operation of a window where a document is located.
The drawing of the windows of the software is based on the existing X11 graphical interface protocol and the gtk graphic library of the domestic operating system.
And 130, acquiring a target document of the closed window, and forcibly encrypting the target document.
The forced encryption method is based on a domestic operating system, adopts hook technology, and combines X11 graphical interface development technology, gtk graphical interface development technology, JNI technology and the like. And then, aiming at different office software and complex conditions thereof, the targeted processing is carried out, and the correct and error-free forced encryption is realized.
Meanwhile, the document operation of the office software is controlled by using a common method from the most basic. The document office is accompanied by the opening and closing of the document for reading and writing, and the opening and closing of the document are hooked by using a hook technology, so that the hook technology can monitor the whole life cycle of the office software operating document on the premise of not modifying the office software.
The hook technology can monitor the operations of opening, closing, reading, writing and the like of a document, and can monitor the operations of opening, closing and the like of a software interface window by combining the X11 graphical interface development technology and the event function of the hook X11.
The electronic document encryption method for the domestic operating system can be used for forcibly encrypting documents generated by office software on the domestic operating system, an operator does not need to do partial manual operation, misoperation is avoided, and office efficiency is improved; the method plays a promoting role in improving the risk resistance of enterprise infrastructure and information systems; the safety of key information infrastructure and important information systems is guaranteed, and the safety of business systems of enterprises and public institutions is improved comprehensively; the safety guarantee capability of key infrastructure and an important information system is further enhanced; good demonstration effect is brought to the interior of an enterprise, so that the competitiveness of the enterprise is improved; the demonstration function can be expanded to the whole IT industry, and huge social benefits are generated.
