Embodiment
Below in conjunction with accompanying drawing, a kind of user ID authentication method of the present invention and device are carried out detailed explanation with specific embodiment.
For the convenience of explaining; The embodiment of the invention describes with the instance among Fig. 2; In Fig. 2, the digital signature that the user A in the Web Service authentication system uses the public key information of the user B that stores in its virtual PKI storehouse that trusted parties user B is sent is carried out authentication (certainly, in Web Service authentication system; The trusted parties user of user A can also have one or more except user B, for example can also comprise user C, user D or the like).The virtual PKI storehouse of user A generates through the public key information in the PKI source is loaded in the internal memory, and concrete visioning procedure is following:
Shown in Fig. 3 A, the constructive process in the virtual PKI storehouse that the embodiment of the invention provides comprises the steps:
When at first connecting between each trusted parties user and the user A, all can the PKI of oneself be sent to user A, user A automatically is stored to the PKI that receives in the PKI source.
Different with prior art; Public key information in the PKI source adopts the mode of separating with digital certificate to store; Can there be various ways in the PKI source; Include but not limited to database, file or the like, because the public key information storage form in the PKI source no longer is the static file form, but the form of the non-static files such as for example database that adopt; Public key information in the form of this non-static file can be easily, immediately make amendment, increase or delete, and is different fully with the update mode of static files such as existing digital certificate or certificate repository.The PKI source can be stored in this locality of user A, also can be stored on the network side third-party server of user A trust, and the present invention does not do any qualification to concrete memory location, PKI source.
For example when a certain trusted parties user's PKI took place to upgrade, this trusted parties user can send to user A with upgrading back PKI derivation, after user A receives the PKI after this user upgrades, uses this PKI to upgrade public key information corresponding in the PKI source.
For example when increasing new trusted parties user, user A can be added into the new trusted parties client public key that receives in the PKI source again; Perhaps
When the trusted parties user reduces, the public key information deletion that user A can be directly corresponding with this trusted parties user in the PKI source.
The Axis2 framework that the embodiment of the invention is increased income at Java (functions such as the issue of the mutual each side of Axis2 framework support Web Service message, parsing; For the image statement; Below be called Web Service and resolve release module) the basis on the realization function of its existing public key acquisition module is expanded, realized the constructive process in virtual PKI storehouse with the mode of software module.But the embodiment of the invention does not limit which kind of Software tool of concrete employing do not develop, the embodiment of the invention is merely a kind of preferable embodiment.Certainly, the mode that mode can also adopt software and hardware to combine is created in virtual PKI storehouse, and the embodiment of the invention is not done any qualification to this.
