Configuration information relevant with user configuration surroundings in the operating system is always stored with certain mode, like configuration file.Be the example explanation below with Windows.
Windows operating system environment for use variable and registration table come leading subscriber environment configurations information.
(1) environmental variance
Environmental variance is the character string that comprises about the environmental information of system and current login user.Some software programs use this information to confirm to place wherein file (like temporary file).
In installation process, Windows setup is with the allocating default system variable, like the path of Windows file.The so-called system environment variable of this type of environmental variance.
The user environment variable can be added, revises or deleted to Any user.These variablees are set up by Windows setup, some program and user.These environmental variances are commonly referred to as the user environment variable.
Technology of the present invention is mainly revised the user environment variable.For example, the memory location of user " my document ", the temporary file of Internet Explorer adds the memory location, or the like.
Because environmental variance is heritable, each process has the different environment variant duplication.Like this, only need when technological initialization, to set environmental variance, just all duplicate these environmental variance copies by the program that this technology starts.
(2) registration table
Registration table is a huge relevant database that is used for the various configuration informations of centralized and unified management system of windows operating system, and it is the basis and the core of windows operating system.Environmental variance also is kept in the registration table.
Write down the information of system's various aspects in the registration table; The interrelated data that roughly comprise the various software programs of user installation to the computing machine; The hardware configuration information (comprise behind the computer starting equipment such as the flash disk and the existing various apparatus configurations information etc. of plug and play) automatically that also comprises computing machine; Also depositing the installation of controlling windows os starting, hardware drive program and the configuration parameter that starts the various application programs of windows in addition in the registration table, these data play the core control action in whole windows operating system.
Technology of the present invention is mainly paid close attention to the registry information relevant with the user individual configuration surroundings.The preservation position of user Outlook Express inbox for example, homepage of InternetExplorer or the like.
Comprehensively to the analysis of environmental variance and registration table, it is fully feasible peeling off the user individual relevant configuration information.
3, the transparent technique for packing of system call
The essence of system call technique for packing is exactly between system call that the user uses and the actual function that realizes, to insert code, so that intercept and capture the information such as call parameters of user program.
In Windows, technology of the present invention is is mainly intercepted and captured among the Windows API the API of registry operations, and this can pass through the Detours tool implementation.Thereby the Detours developing instrument that Microsoft provides can be through being overwritten in the code interception win32 function in the internal memory for objective function.The Detours software package can also be injected into dll and data slot (being referred to as useful load) arbitrarily arbitrarily in the middle of the win32 binary file.
Behind the registration table api function through the routine call of detours plug-in mounting, can through the parameter of api function come the operand of discriminant function be we the operand that will pay close attention to.If, then operation is redirected to privately owned registration table through privately owned registration table api function, otherwise, then return and let the windows registry handling function continue carry out.
4, the reference implementation of system
Technology of the present invention realizes in Windows XP system, its concrete composition as follows:
Windows?XP?SP2；
USB 2.0 portable hard drives;
The present invention's technology start-up routine and plug-in mounting DLL;
The configuration file of user individual environment
(1) sets
During technical application program initialization of the present invention, the user environment variable is set through calling Windows API.Because the inherited characteristics of environmental variance just need not reset environmental variance by this technology application program started.
The user environment variable that is provided with during the initialization of the present invention's technology comprises: ALLUSERPROFILE, APPDATA, CommonPogramFiles, HOMEDRIVE, HOMEPATH, TEMP, TMP, USERPROFILE or the like.
(2) extraction is disposed relevant registry information with the user
The registry entry (be privately owned registration table) relevant with the personalized configuration surroundings of Windows user is more; Mainly comprise SOFTWARE USER SHELLFOLDERS, SOFTWARE USER SHELLFOLDERS or the like.The main registry entry that extracts under HKEY_LOCAL_AMCHINE and the HKEY_CURRENT_USER of the present invention's technology; Relevant registry entry under other root key with the user individual configuration surroundings; All be to be combined according to ad hoc rules by the registry entry under these two root keys, concrete rule is please developed document referring to MSDN.
Technology of the present invention is saved in the registration table content that extracts below user.r and the system.r, representes the registry entry under HKEY_CURRENT_USER and the HKEY_LOCAL_MACHINE respectively.
(3) parcel registry operations
The registration table API of the main parcel of the present invention's technology comprises: RegCreateKeyEx, RegOpenKeyEx, RegCloseKey; RegDeleteKey, RegSetValueEx, RegQueryValueEx; RegEnumKeyEx, RegEnumValue, RegDeleteValue; RegQueryInfoKeyEx, RegOpenCurrentUser, RegOpenUserClass.
The overall procedure of parcel is following:
Step1: initialization mainly comprises the initial configuration file.
Step2: intercept and capture relevant Registry API Calls, and judge as follows:
If read operation if operand also has, is then read content recorded in the privately owned registration table in privately owned registration table; If write operation (comprise modification, deletion increases) then is redirected to privately owned registration table, the registration table content on this machine is not changed.
Behind the parcel function (wide byte function (the function name end is W) has only been described here as follows; Narrow byte function (the function end is A) carries out calling wide byte function after the A/W conversion to parameter again); Wherein the function of Real_ beginning shows Windows Registry API, the privately owned Registry API of function representation of My beginning.Mine_RegCreateKeyExW(HKEY?a0，LPCWSTR?a1，DWORD?a2，LPWSTR?a3，DWORD?a4，REGSAM?a5，LPSECURITY_ATTRIBUTES?a6，PHKEY?a7，LPDWORD?a8))
