Description
Technical field
The present invention relates to field of computer technology, refer to a kind of method and apparatus that solves multi graphic identification and verifying dynamic link library collision especially.
Background technology
The serial operating system of window (Windows), as Windows NT, Windows 2000, Windows XP and Windows 2003 etc., a graphical identification and a checking (GINA who is called msgina.dll is provided, Graphical Identification and Authentication) dynamic link library (DLL, Dynamic Link library) file.This GINA dynamic link library that is called msgina.dll provides interactively system login interface for the user.Can move a system program that is named as window login (Winlogon) during the Windows os starting, this system program can load GINA DLL and call wherein related function, finishes interactively system login operation.Fig. 1 is the interactive system login interface figure that GINA DLL that existing Windows2000 operating system carries provides.
Prior art also allows software developer's set of rule according to the rules to realize the GINA DLL that oneself customizes except the GINA DLL that the above-mentioned msgina.dll of being called is provided.A lot of application scenarioss all need to adopt the GINA DLL of customization, as following two application scenarioss:
Application scenarios one: single-sign-on is used
When logining Windows operating system, the user of an enterprise need correct input username and password to enter Windows operating system by login.If this enterprise has used certain network insertion software, the authentication that promptly needs the user to finish network insertion could allow accesses network, and the user need import information such as username and password once more.If the use of twice input is same set of user name encrypted message, then the enterprise customer can propose the demand of single-sign-on naturally, can login behind user name encrypted message of input when promptly logining Windows and enter Windows operating system, again can access network.Network insertion software provides developer's customization GINA DLL storehouse can satisfy this demand, customization GINA DLL gets access to the information such as user name password of user's input when promptly logining Windows, do the operation of network access authentication earlier with these information, do the operation of login Windows subsequently again.
Application scenarios two: USB smart card and Windows login are integrated and are used
This application need user installs USB smart card and relevant driver on computers, there is PIN (PIN in the smart card, Personal Identification Number), the user will login Windows, except correct input username and password information, also must correct input PIN code.Only need pull out smart card when the user will leave temporarily, computing machine automatically locks; Have only and insert smart card once more and import correct PIN code and could enter system once more and continue to use.This application need customize GINA DLL equally and realize.
Although prior art provides GINA DLL customizing mechanism for the software developer, there is a limitation in this mechanism, and making to have the GINA DLL of a manufacturer to be loaded by system program winlogon.A manufacturer will make the GINA DLL that oneself customizes work, the GINA DLL title that oneself customizes need be recorded the assigned address of registration table, this assigned address is: HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion " GINA DLL " attribute under the Winlogon, for example, the ABC_GinaHoo k.dll of customization is saved in the assigned address of registration table, be HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion the value of " GINA DLL " attribute of dividing into of Winlogon be set to ABC_GinaHook.dll.
When the GINA DLL of two manufacturer's customizations wished to come into force on same computing machine, problem had just come out: the GINA DLL that install the back comes into force and can cause the GINA DLL that installs earlier to lose efficacy.The conflict of Here it is a plurality of GINA DLL.But how prior art does not solve the scheme of a plurality of GINADLL conflicts.
Summary of the invention

Embodiment
Core concept of the present invention is: when the Windows os starting, leading GINA DLL is loaded and operation by the Winlogon system program, and each subordinate GINA DLL is by leading GINA DLL or the subordinate GINA DLL loading and the operation of its upper level, a plurality of like this GINA DLL just can collaborative work, and not producing conflict, concrete scheme is as shown in Figure 2.
Fig. 2 is the process flow diagram of the method for a kind of many GINA of solution DLL conflict of the embodiment of the invention.As shown in Figure 2, this method may further comprise the steps:
GINA chained list in the said process generates when leading GINA DLL and individual subordinate GINA DLL are installed, preserve the chain relationship information between leading GINA DLL and each the subordinate GINA DLL in the GINA chained list, according to such scheme as seen, this chain relationship information comprises at least: the title of leading GINA DLL, the title of each subordinate GINA DLL, the external interface parameter sets of each subordinate GINA DLL, the external interface title of each subordinate GINA DLL, and the chain type relationship between superior and subordinate between each GINA DLL.
For making purpose of the present invention, technical scheme and advantage clearer, below enumerate embodiment, the present invention is described in more detail.
According to the solution of the present invention, the GINA DLL of a customization may be leading GINA DLL in actual applications, also may be subordinate GINA DLL, needs when mounted, defines as the case may be.
1, when name of installation is called the GINA DLL of A_GINA.dll, at first judge and whether had leading GINA DLL under the current operating system, if there is no, then the title " A_GINA.dll " of preserving this GINA DLL that will install under the registration table assigned address (be about to HKEY_LOCAL_MACHINE SOFTWARE Microsoft WindowsNT CurrentVersion GINA DLL property value under the Winlogon be set to A_GINA.dll), and in the GINA chained list, fill in the input parameter set that A_GINA.dll can provide, represent with attribute " Capability_A " in the present embodiment, also in the GINA chained list, fill in external interface title " Interface_A " and the external interface parameter sets " ParamSet_A " of A_GINA.dll simultaneously, with A_GINA.dll itself be saved in default directory (as C: WINDOWS system32) under.So far A_GINA.dll installs, and A_GINA.dll has been installed into leading GINA DLL.
Fig. 3 is the synoptic diagram behind the installation A_GINA.dll in the embodiment of the invention.As shown in Figure 3, after the Windows system restart, Winlogon is known A_GINA.dll according to the title of the leading GINADLL that the registration table assigned address is preserved down, load A_GINA.dll down from default directory (C: WINDOWS system32), (for example call specified interface that among the A_GINA.dll one meets the GINA code requirement, this specified interface can be the interface function that name is called WlxLoggedOutSASDlgProc), this specified interface obtains the external interface parameter sets " ParamSet_A " of A_GINA.dll by existing mode, with the external interface " Interface_A " of the parameter call A_GINA.dll in " ParamSet_A ".Arrow is represented to load and call in Fig. 3.Wherein, Winlogon is according to the title of the GINA DLL that preserves under the registration table assigned address, load this GINA DLL, call the specified interface function among this GINA DLL then, the process that the external interface parameter set that obtains this GINA DLL by this specified interface function merges the external interface call this GINA DLL is a prior art.
In the present embodiment, " Capability_A " attribute of filling in A_GINA.dll in the GINA chained list is the usefulness that defines leading and subordinate GINA DLL during for a plurality of GINA DLL of subsequent installation.Use 32 integer representation " Capability " attribute in the present embodiment, big-endian be called the 1st, the 2nd ..., the 32nd, each corresponding input parameter, this position is 1 to express support for, and is 0 to represent not support.Stipulate that the 1st to the 4th is represented parameter " user name ", " password ", " login position " and " login window handle " respectively.If then Capability_A=0x0000000F just represents that A_GINA.dll supports " user name ", " password ", " login position " and " login window handle " four parameters are provided, and only supports this four parameters.
The GINA chained list can be realized with multiple expression way, provides the GINA chained list of realizing with the file of ini form here, and after A_GINA.dll installed, the form of GINA chained list was as follows:
[First?GINA?DLL]
GINA?DLL＝A_GINA.dll
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Wherein, " First GINA DLL " expression is leading GINA DLL.
2, when name of installation is called the GINA DLL of B_GINA.dll, A_GINA.dll as leading GINA DLL has been arranged under the current system, there are following three kinds of situations in input parameter set and external interface parameter sets that then more current B_GINA.dll that will install and mounted A_GINA.dll can support:
If (2-1) the input parameter set " Capability_B " that can support of B_GINA.dll can comprise A_GINA.dll external interface parameter sets " ParamSet_A ", with B_GINA.dll itself be saved in default directory (as C: WINDOWS system32) under, and B_GINA.dll is set to leading GINA DLL, A_GINA.dll is set to the subordinate GINA DLL of B_GINA.dll, the GINA DLL attribute that is specially under the registration table assigned address is set to GINA DLL=B_GINA.dll, and the content alteration of GINA chained list is:
[First?GINA?DLL]
GINA?DLL＝B_GINA.dll
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
Next＝A_GINA.dll
[A_GINA.dll]
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Wherein, attribute " Next=A_GINA.dll " expression A_GINA.dll is the subordinate GINA DLL of B_GINA.dll.
Need to prove that set A comprises set B in embodiments of the present invention, be meant that all elements can both find in the set B in set A.
Fig. 4 is the synoptic diagram after under the situation shown in (2-1) B_GINA.dll being installed.As shown in Figure 4, after the Windows system restart, Winlogon is known B_GINA.dll according to the title of the leading GINA DLL that the registration table assigned address is preserved down, load B_GINA.dll down from default directory (C: WINDOWS system32), call a specified interface that meets the GINA code requirement among the B_GINA.dll, this specified interface obtains the external interface parameter sets " ParamSet_B " of B_GINA.dll by existing mode, with the external interface " Interface_B " of the parameter call B_GINA.dll in " ParamSet_B ".The external interface of B_GINA.dll " Interface_B " is realized the service logic of this B_GINA.dll self, and be A_GINA.dll according to the next stage subordinate that " Next " attribute of the B_GINA.dll in the GINA chained list finds B_GINA.dll, from this GINA chained list, obtain the external interface parameter " ParanSet_A " of A_GINA.dll, from default directory (as C: WINDOWS system32) load down A_GINA.dll, with parameter call " Interface_A " in " ParanSet_A "; " Interface_A " realizes the service logic of this A_GINA.dll self.
If (2-2) the input parameter set " Capability_A " that can support of A_GINA.dll can comprise B_GINA.dll external interface parameter sets " ParamSet_B ", with B_GINA.dll itself be saved in default directory (as C: WINDOWS system32) under, and B_GINA.dll is set to the subordinate GINA DLL of A_GINA.dll, and the content alteration that is specially the GINA chained list is:
[First?GINA?DLL]
GINA?DLL＝A_GINA.dll
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Next＝B_GINA.dll
[B_GINA.dll]
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
Fig. 5 is the synoptic diagram after under the situation shown in (2-2) B_GINA.dll being installed.Similar described in the process of A_GINA.dll in Fig. 5 after the Windows system restart and B_GINA.dll collaborative work and Fig. 4, just A_GINA.dll and B_GINA.dll exchanged the role and with, no longer repeat here.
If (2-3) the input parameter set " Capability_B " that can support of B_GINA.dll can not comprise A_GINA.dll external interface parameter sets " ParamSet_A ", and the input parameter that A_GINA.dll can support set " Capability_A " can not comprise A_GINA.dll external interface parameter sets " ParamSet_B ", the then different collaborative works of these two GINA DLL, can only abandon the installation of B_GINA.dll, B_GINA.dll perhaps is installed by force, and at this moment A_GINA.dll lost efficacy.If B_GINA.dll is installed by force, then the GINA chain changes to following form:
[First?GINA?DLL]
GINA?DLL＝B_GINA.dll
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
Fig. 6 is the synoptic diagram after by force B_GINA.dll being installed under the situation shown in (2-3).
If there has been plural GINA DLL under the 3 current systems, when promptly having had a leading GINA DLL and more than one subordinate GINA DLL, if a new GINADLL is installed, then need to begin to compare step by step from leading GINA DLL, finally find a position of inserting new GINADLL, this position may be begin chain (being that new GINA DLL is as leading GINA DLL), also may be last-of-chain, also may be certain position in the middle of the GINA DLL chain.
Here supposing the system has been installed A_GINA.dll and B_GINA.dll, and installation situation as shown in Figure 5, the current new C_GINA.dll of installation that needs, then begin the input parameter that the more current successively C_GINA.dll that will install and mounted each GINA DLL can support and gather and the external interface parameter sets, have following four kinds of situations from leading GINA DLL:
If (3-1) the input parameter set " Capability_C " that can support of C_GINA.dll can comprise A_GINA.dll (leading GINA DLL) external interface parameter sets " ParamSet_A ", with C_GINA.dll itself be saved in default directory (as C: WINDOWS system32) under, and C_GINA.dll is set to leading GINA DLL, A_GINA.dll is set to the subordinate GINA DLL of C_GINA.dll, the value that is specially the GINA DLL attribute under the registration table assigned address is set to C_GINA.dll, and the content alteration of GINA chained list is:
[F?irst?GINA?DLL]
GINA?DLL＝C_GINA.dll
Capability＝<Capability_C>
Interface＝<Interface_C>
ParamSet＝<ParamSet_C>
Next＝A_GINA.dll
[A_GINA.dll]
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Next＝B_GINA.dll
[B_GINA.dll]
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
Fig. 7 is the synoptic diagram after under the situation shown in (3-1) C_GINA.dll being installed.As shown in Figure 7, when window Windows os starting, the Winlogon system program loads A_GINA.dll according to the title C_GINA.dll of the leading GINA DLL that the registration table assigned address is preserved down down from default directory, call a specified interface that meets the GINA code requirement among the A_GINA.dll, this specified interface obtains the external interface parameter " ParamSet_C " of C_GINA.dll, and with the external interface " Interface_C " of the parameter call C_GINA.dll in " ParamSet_C "; " Interface_C " realizes the service logic of C_GINA.dll self, and find the position of C_GINA.dll correspondence according to the GINA chained list, there is the A_GINA.dll of next stage to exist according to the Next Attribute Discovery, then from the GINA chained list, obtain the external interface parameter " ParamSet_A " of A_GINA.dll, load A_GINA.dll, with the external interface " Interface_A " of the parameter call A_GINA.dll in " ParamSet_A "; Afterwards, for each subordinate GINA DLL, when the external interface of this subordinate GINA DLL is called by upper level GINA DLL, the external interface of this subordinate GINA DLL is realized beyond the service logic of this subordinate GINA DLL self, judges according to the GINA chained list whether this subordinate GINADLL exists next stage GINA DLL; If exist, then from the GINA chained list, obtain the external interface parameter of this next stage subordinate GINA DLL, load this next stage subordinate GINA DLL, with this external interface of next stage subordinate GINA DLL again of the external interface parameter call of described next stage subordinate GINA DLL; If there is no, process ends then.
As seen, in embodiments of the present invention, the external interface of a GINA DLL need be realized two parts logic function: first is a service logic of finishing this GINA DLL, is prior art as for the service logic that how to realize this GINA DLL; Second portion is the collaborative work of finishing many GINA DLL, promptly is specially to judge it is the GINA DLL that has next stage, if exist then load and move the GINA DLL of this next stage.
If (3-2) the input parameter set " Capability_A " that can support of A_GINA.dll can comprise C_GINA.dll external interface parameter sets " ParamSet_C ", and the input parameter that C_GINA.dll can support set " Capability_C " can comprise B_GINA.dll external interface parameter sets " ParamSet_B ", with C_GINA.dll itself be saved in default directory (as C: WINDOWS system32) under, and C_GINA.dll is inserted between A_GINA.dll and the B_GINA.dll, the content alteration that is specially the GINA chained list is:
[First?GINA?DLL]

Fig. 9 is the synoptic diagram after under the situation shown in (3-3) C_GINA.dll being installed.
If (3-4) above-mentioned three kinds of situations are not, then C_GINA.dll can not with already present A_GINA.dll and B_GINA.dll collaborative work, abandon the installation of C_GINA.dll this moment, and C_GINA.dll perhaps is installed by force, and then A_GINA.dll and B_GINA.dll lost efficacy.
In the process of each GINA DLL of above-mentioned installation, all GINA DLL has been saved in default directory (as C: WINDOWS system32) under, like this when loading GINA DLL, all obtain the GINA DLL that will load under the described default directory and load.
In another embodiment of the present invention, can also be in the process that each GINA DLL is installed, all each GINA DLL has been saved under the different catalogues, at this moment, the directory information that need be in the GINA chained list corresponding with the title of each GINA DLL this GINA DLL of preservation is saved.When loading certain GINA DLL, just can obtain the directory information that the GINA DLL that will load is saved, and then obtain and to load GINA DLL and load from the GINA chained list.
For example, with situation shown in Figure 5 is example, suppose A_GINA.dll as leading GINA DLL be saved to default directory (as C: WINDOWS system32) under, but as the B_GINA.dll of subordinate be saved to another catalogue (as C: WINDOWS GINA DLL) under, then can increase " Location " attribute and represent the catalogue that corresponding IGNA DLL is saved in the GINA chained list, the concrete form of GINA chained list can be as follows:
[First?GINA?DLL]
GINA?DLL＝A_GINA.dll
Location＝C：\WINDOWS\system32
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Next＝B_GINA.dll
[B_GINA.dll]
Location＝C：\WINDOWS\GINA?DLL
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
Describe the process that how to realize installation and the collaborative work of many GINA DLL among the present invention among the embodiment of front, next provided the mode of a GINA DLL of unloading from system.
When a GINA DLL no longer is used and need unloads, to guarantee not influence the collaborative work of other existing GINA DLL from system, for this reason, provide the contraction method of following GINADLL chain in embodiments of the present invention:
If (1-a) the current GINA DLL that will unload exists upper level GINA DLL and next stage GINA DLL simultaneously, then allow the upper level GINADLL of the current GINA DLL that will unload directly point to the next stage GINA DLL of the current GINA DLL that will unload at the GINA chained list.
For example, in GINA DLL chain shown in Figure 7, if unloading A_GINA.dll, then in the GINA chained list, the value of the attribute " Next " of C_GINA.dll (upper level of A_GINA.dll) is revised as B_GINA.dll (next stage of A_GINA.dll).
If (1-b) there is upper level GINA DLL in the current GINA DLL that will unload, but do not have next stage GINA DLL, then the upper level GINA DLL with the current GINA DLL that will unload is changed to last-of-chain.
For example, in GINA DLL chain shown in Figure 7, if unloading B_GINA.dll then deletes the attribute " Next " of A_GINA.dll (upper level of B_GINA.dll) in the GINA chained list.
If (1-c) there is next stage GINA DLL in the current GINA DLL that will unload, but do not have upper level GINA DLL, then the next stage GINA DLL with the current GINA DLL that will unload is changed to leading GINA DLL.
For example, in GINA DLL chain shown in Figure 7, if unloading C_GINA.dll, then the GINA DLL the registration table assigned address under is set to GINA DLL=A_GINA.dll (next stage of C_GINA.dll), and in the GINA chained list A_GINA.dll is designated and dominates GINADLL.
(2) full detail of the GINA DLL that deletion is described to be unloaded from the GINA chained list is about to whole clauses and subclauses deletion from the GINA chained list of GINA DLL to be unloaded.
For example, in GINA DLL chain shown in Figure 7, when not unloading A_GINA.dll, the content of GINA chained list is:
[First?GINA?DLL]
GINA?DLL＝C_GINA.dll
Capability＝<Capability_C>
Interface＝<Interface_C>
ParamSet＝<ParamSet_C>
Next＝A_GINA.dll
[A_GINA.dll]
Capability＝<Capability_A>
Interface＝<Interface_A>
ParamSet＝<ParamSet_A>
Next＝B_GINA.dll
[B_GINA.dll]
Capability＝<Capability_B>
Interface＝<Interface_B>
ParamSet＝<ParamSet_B>
After A_GINA.dll was unloaded, the content of GINA chained list was:
[First?GINA?DLL]
GINA?DLL＝C_GINA.dll
Capability＝<Capability_C>
Interface＝<Interface_C>
ParamSet＝<ParamSet_C>
Next＝C_GINA.dll
[B_GINA.dll]
C?apability＝<Capability_B>
