Embodiment
Please refer to Fig. 1, Fig. 1 is the synoptic diagram of an interface management flow process 10 that is used for a computer system of the embodiment of the invention.But the external interface of interface management flow process 10 quick closedown computer systems (as USB, Bluetooth, e-SATA, PCI-E etc.), to strengthen information security, it includes following steps:
Step 100: beginning.
Step 102: receive a control signal, and produce an instruction, this control signal is used for closing an external interface of this computer system.
Step 104:,, close a controller corresponding to this external interface by a south bridge controller of this computer system according to this instruction.
Step 106:, notify an operating system of this computer system, to close function corresponding to a driver of this external interface according to this instruction.
Step 108: finish.
According to interface management flow process 10, the present invention is receiving when being used for closing a control signal of external interface, produces corresponding instruction, and closes corresponding controller by the south bridge controller earlier in view of the above, reinforms the function that operating system is closed driver.In other words, the present invention does not need to restart computing machine, can close external interface, therefore can promote the convenience when using.
It should be noted that the synoptic diagram that Figure 1 shows that interface management flow process 10, those of ordinary skills should do different variations in view of the above, and are not limited thereto.For instance, in interface management flow process 10, the producing method of control signal is not limited to ad hoc fashion, it can be to be produced by a hot key, or by the application program generation that is installed in the operating system, in addition, produced by remote controllers, and exported to computer system by network.In addition, when receiving control signal, the present invention also can require the user to input a password, and when correct, just produces instruction; Otherwise, then do not produce instruction.Moreover if external interface is worked, then when receiving control signal, the present invention also can require the user to import a confirmation, and when confirmation indication hard closing external interface, just produces instruction; Otherwise, then do not produce instruction.In this case, aforesaid operations can reduce an interface management flow process 20, as shown in Figure 2.
Interface management flow process 20 is derived for interface management flow process 10, and it comprises following steps:
Step 200: beginning.
Step 202: judge whether to start the interface management function.If carry out step 204; If not, carry out step 220.
Step 204: judge whether to receive a control signal, this control signal is used for closing an external interface of this computer system.If carry out step 206; If not, wait for this control signal.
Step 206: judge whether password-protected.If carry out step 208; If not, carry out step 210.
Step 208: judge whether password is correct.If carry out step 210; If not, carry out step 220.
Step 210: judge whether external interface works.If carry out step 212; If not, carry out step 214.
Step 212: whether the affirmation information of judging the user indicates the hard closing external interface.If carry out step 214; If not, carry out step 220.
Step 214: produce an instruction.
Step 216:,, close a controller corresponding to this external interface by a south bridge controller of this computer system according to this instruction.
Step 218:, notify an operating system of this computer system, to close function corresponding to a driver of this external interface according to this instruction.
Step 220: finish.
Therefore, by interface management flow process 20, behind interface management function on of the present invention, the present invention can carry out cryptographic core to and according to the affirmation information of forced shutdown, judge whether to produce corresponding instruction.Thus, can avoid user's error starting, and the work of protection external device.In addition, it should be noted that the present invention not only closes single external interface, also can be set at and close a plurality of external interfaces or all external interfaces simultaneously that its working method is all similar.
Therefore, by the present invention, the user can be fast and the external interface of the system that shuts down computer effectively, to strengthen information security.About implementation of the present invention, those of ordinary skills should realize interface management flow process 10 or 20 with application program, solid, hardware etc. according to above stated specification.
For instance, please refer to Fig. 3, Fig. 3 is the synoptic diagram of an interface management apparatus 30 of the embodiment of the invention.Interface management apparatus 30 includes instruction generation unit 300, one first control module 302 and one second control module 304, in order to realize interface management flow process 10 or 20.Instruction generation unit 300 includes a receiving element 306, an indicating member 308, a confirmation unit 310 and a generation unit 312.Receiving element 306 is used for receiving a control signal CTR; Indicating member 308 is used for requiring a password; Confirmation unit 310 is used for requiring a confirmation when external interface is worked; And generation unit 312 is used for content according to password checked result and confirmation, produces an instruction CMD.First control module 302 is used for by a south bridge controller 314, closing the controller corresponding to external interface according to instruction CMD.Second control module 304 is used for notifying an operating system 316, to close the function corresponding to a driver of external interface according to instruction CMD.Interface management apparatus 30 is in order to realize interface management flow process 10 or 20, and detailed operation situation or variation pattern can not given unnecessary details at this further with reference to above stated specification.
In known technology, in the time will closing external interface, user's start again earlier enters BIOS (if having password to need first key feeding cipher), closes the function of this interface again, stores related setting, starts shooting again at last and enters operating system.Under comparing, in the present invention, the user does not need to restart computing machine, can close external interface, therefore can promote the convenience when using.
In sum, the present invention does not need to restart computing machine, can close external interface, and therefore, the present invention also can promote the convenience when using except promoting the information security.
The above only is preferred embodiment of the present invention, and every claims scope is done according to the present invention equivalent variations and modification all should belong to covering scope of the present invention.
