Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
The present invention can be applied to the authenticating user identification and the data protection of any individual private software.Present embodiment is an example with dynamic password software, further specifies content of the present invention and embodiment.
Dynamic password software is the development along with Internet service; for satisfying a kind of cryptoguard mode that more and more urgent hope better protection user account number and password occur that is used for; on basis in conjunction with the traditional static cryptographic technique, a kind of dynamic password technology that development forms.Use dynamic password software, when the user logins Internet service, need to use the dynamic password computed in software go out the disposal password of a dynamic change at every turn, and together be input to the service server end with static password and verify.And a cover dynamic password software can be managed a plurality of account numbers, but the use of software is individual private.
As shown in Figure 1, software is behind each the startup, the USB bound flag is read in the capital earlier, judges whether to have finished the USB binding then: if finish, then software can scan the whole USB device that have been connected to computing machine, and judge whether the USB bound device exists, if do not detect, then point out the user to insert the USB bound device, and continue scanning, if successfully detected, then enter software master interface; If do not finish the USB binding as yet, then software can real time scan be connected to whole USB device of computing machine and have generated the list of devices of a real-time update, and the user need to select the equipment of binding from tabulation then, and is last, write the USB bound flag, enter software master interface.
As shown in Figure 2, the user is when using business, and things are as usual, and selecting oneself needs the account number of use, and click generates password and gets final product.During running software, even software is in waiting status, for example minimized in Windows system the inside, the whole USB device that are connected to computing machine also can timing (for example per second) be scanned in the backstage, and judge whether the USB bound device is pulled out, if do not have, then continue timing scan, be pulled out if detect the USB bound device, locked software and point out the user to insert the USB bound device immediately then, software can real time scan be connected to whole USB device of computing machine then, and judge whether the USB bound device exists, if detect correct USB bound device, then unlock and recover normal condition, continue timing scan then; If do not detect, whether then check and overtime (for example 60 seconds), then continue real time scan, otherwise software to withdraw from automatically if not overtime.
As shown in Figure 3, dynamic password software can be used some users' significant data when calculating dynamic password, and these data are to encrypt storage.Need to read out the hardware information (for example manufacturer, product type and sequence number etc.) of USB bound device in the process of encryption and decryption, that is to say, the hardware information of USB bound device is the part of key, the necessary condition that to have this USB bound device be the calling party data.When storaging user data, software at first reads the hardware information of USB bound device, handles and obtain key then, uses this secret key encryption user data, obtains encrypt data and storage at last.When being written into user data, also at first need to read the hardware information of USB bound device, handle and obtain key then, use this secret key decryption user data, obtain clear data at last and be written into.If data are by bootlegging owing to lack the hardware information of USB bound device, other people be can't calling party significant data.
The present invention is that the USB device with individual subscriber private software and user's appointment associates, and preferably resolves the problem of authenticating user identification and data protection.Improved the security of software.All within above-mentioned spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
