Abstract
The present invention provides one kind of effective method of unlocking PC. The control program of USB system unit controller based on BIOS environment and the USB Key detection and identity verification program are written into Boot Rom in network card. After the PC is booted and when the system loads the control program of USB system unit controller and the USB Key detection and identity verification program from Boot Rom in network card and runs the programs, the system performs the detection and identity distinction on USB Key inserted in the USB interface to complete unlocking PC.
Description
Technical field
The method of the present invention about realizing that PC locks starts the back at PC specifically and load usb host controller control and USB Key detection and authentication program and operation from the Boot Rom of network interface card, thereby realizes the method for the start lock in the start-up course.
Background technology
Along with the raising of computer technology, personal computer (PC), particularly laptop computer applications is more prevalent.Many people can be some to the hard disk the inside of the very useful data storage of individual or company at computer.How to prevent that data important in the computer from illegally being stolen, prevent that the problem of any computer of opening oneself of disabled user and so on relevant PC safety is subjected to people's attention, particularly business people day by day.People wish and can protect the computer of oneself not encroached on by the handlebar electron key, so the notion of USBKey has just produced, need the problem of solution and how USB Key is carried out identification with regard to becoming PC start lock very much.After present PC start lock still just is confined to the starting up and enters Windows operating system, USB Key is carried out identification, if identification error then pin computer screen.A kind of like this method is also dangerous, and the disabled user can move below Windows by some little software, thereby cracks screen protection.In this sense, it only is to have realized the screen protection lock, and is not real start lock.
The stage that can effectively realize starting up lock function in the PC start-up course has three: 1. protect in BIOS ROM; 2. protect in the program in network interface card Boot Rom.Under the both of these case, PC is not load operation system also, so can't move all kinds of cracking.First kind of scheme needs the mainboard business men to add the code of USB Key authentication in bios program, needs the specific group of PC safety to remove to revise BIOS and the not conference of mainboard business men that program code is cherished word such as gold among the BIOS EPROM is one.And in network interface card Boot Rom, write start lock code, can extraordinary realization PC starting up lock function.
Summary of the invention
For above purpose, the invention provides a kind of method at network card bootstrap zone stage realization starting up lock function, this method comprises:
Based on usb host controller control under the BIOS environment and USB Key detects and authentication program writes among the Boot Rom of network interface card;
The PC starting up finishes after the BIOS detection, and PC is loaded into internal memory and operation to the Automatic Program that deposits network interface card Boot Rom in;
Program among the network interface card Boot Rom is taken over the usb host controller of BIOS control and is come, and USB Key is detected and authentication;
Description of drawings
In claims of present patent application, pointed out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, relevant structure that can better understand the present invention and implementation method with and purpose, feature and advantage.
When Fig. 1 has starting up lock function of the present invention, the start-up course of PC
The main program flow chart of Fig. 2 usb host controller
The interrupt routine process flow diagram of Fig. 3 usb host controller
Fig. 2, Fig. 3 are the usb host controller control program of the embodiment of the invention.Although the invention is not restricted in this respect, for the realization that cooperates Fig. 1 is died in this proposition.
Specific implementation method
In the following detailed description, having described specific details comprehensively understands the present invention so that provide.Yet the professional and technical personnel will appreciate that the present invention also can implement with other similar details.
To have the Boot Rom that writes network interface card based on the program of the control of the usb host controller under the BIOS environment and USB Key detection and authentication;
After the BIOS trace routine is finished in the PC startup, load the program and the operation of network interface card Boot Rom the inside automatically;
Take over usb host controller based on usb host controller control program under the BIOS environment;
By the usb host controller control program, detect USB Key and USB Key is used special-purpose usb data transfer instruction, carry out authentication;
If detect and authentication by then recover the control of bios program again to usb host controller, enter normal start-up course, if not by continue detection.
Though herein declarative description certain this feature of the present invention and a kind of implementation method, for the professional and technical personnel, many modifications, replacement, variation and equivalent substitution will appear.Therefore, protection scope of the present invention is as the criterion by the scope of appended claim.
Claims (3)
1. realize the method for starting up lock function at network card bootstrap zone for one kind, this method may further comprise the steps:
-the code that will have a USB Key authentication function deposits among the Boot Rom of network interface card;
After-PC starts, from the Boot Rom of network interface card, load the usb host controller of taking over BIOS control based on usb host controller control program under the BIOS environment;
-by the usb host controller control program, detect USB Key and USB Key is used special-purpose usb data transfer instruction, carry out authentication;
If-detect and authentication by then recover the control of bios program again to usb host controller, enter normal start-up course, if not by continue detection.
2. a kind of according to claim 1 method at master boot sector realization starting up lock function, it is characterized in that: the code that will have USBKey authentication function deposits among the Boot Rom of network interface card;
3. a kind of according to claim 1 method at master boot sector realization starting up lock function is characterized in that: after PC starts, load the usb host controller of taking over BIOS control based on usb host controller control program under the BIOS environment from the Boot Rom of network interface card.
