In the second embodiment, the processor 201 executes the application to ask the basic input/output system 203 whether to set the pairing password information. The basic input/output system 203 reads the memory device 202 to confirm whether or not the pairing password information is stored. If the basic input/output system 203 does not read the pairing password information, the response processor 201 computer system 20 is not password protected. At this time, the processor 201 executes the application to generate a set of random first pairing password information to encrypt the hard disk device 211, so that the hard disk device 211 can recognize the first pairing password information. At the same time, the processor 201 transmits the first pairing password information to the basic input/output system 203, so that the basic input/output system 203 stores the first pairing password information in the memory device 202 (that is, stored in the basic input and output). In system 203). The basic input output system 203 reports the processor 201 after it has been stored. Finally, after performing the above steps, the processor 201 asks the user whether to restart the electronic device 200 to validate the first pairing password information.

Next, the processor 201 detects that the electronic device 200 is connected to the base device 210, and detects that the hard disk device 211 is in a locked state. Finally, the processor 201 uses the first pairing password information to release the locked state of the hard disk device 211. Through the method described in the third embodiment, after the electronic device 200 enters the operating system, the unlocking operation of the hard disk device 211 can be actively performed and completed without notifying the user.

A fourth embodiment of the present invention illustrates how the electronic device 200 unlocks the hard disk device 211 of the base device 210 using the first pairing password information. In the fourth embodiment, the electronic device 200 is turned on and enters the operating system, and the electronic device 200 is not connected to the base device 210. At this time, the processor 201 actively queries the basic input/output system 203 for the first pairing password information. The basic input/output system 203 reads the first pairing password information and responds to the processor 201. Next, in the fourth embodiment, the user connects the hard disk device 211 to the electronic device 200 through the connection port 212. The basic input/output system 203 receives the connection signal of the base device 210 and notifies the processor 201. At this time, the processor 201 detects that the basic input/output system 203 has obtained that the electronic device 200 has been connected to the base device 210, and detects that the hard disk device 211 is in a locked state. Finally, the processor 201 uses the first pairing password information to release the locked state of the hard disk device 211. Through the method described in the fourth embodiment, after the electronic device 200 is connected to the base device 210, the unlocking operation of the hard disk device 211 can be actively performed and completed without notifying the user.

A fifth embodiment of the present invention illustrates how the electronic device 200 unlocks the hard disk device of the base device 210 using the first pairing password information. 211. In the fifth embodiment, the electronic device 200 has been connected to the port 212 of the base device 210 via the port 206, and the electronic device 200 has been activated and entered into the sleep/sleep mode of the operating system. Since the electronic device 200 is in the sleep/hibernation mode, the hard disk device 211 is in a locked state. Next, when the user operates the electronic device 200 to wake up the electronic device 200 from the sleep/sleep mode, the processor 201 actively executes the application to query the basic input/output system 203 for the first pairing password information. The basic input/output system 203 reads the first pairing password information and responds to the processor 201. Finally, the processor 201 uses the first pairing password information to release the locked state of the hard disk device 211. Through the method described in the fifth embodiment, after the electronic device 200 wakes up from the sleep/hibernation mode, the unlocking operation of the hard disk device 211 can be actively performed and completed without notifying the user.

A sixth embodiment of the present invention exemplifies how to cancel the pairing relationship between the electronic device 200 and the base device 210. In the sixth embodiment, the electronic device 200 has been connected to the port 212 of the base unit 210 via the port 206, and the user has activated the electronic device 200 and entered the operating system. Next, the user selects and executes an application among the operating systems to remove the pairing relationship between the electronic device 200 and the base device 210. In the sixth embodiment, the processor 201 executes the application to ask the basic input/output system 203 whether to set the pairing password information. The basic input/output system 203 reads the memory device 202 to confirm whether or not the pairing password information is stored. If the pairing password information is stored, the basic input/output system 203 returns the pairing password information to the processor 201. In response, the processor 201 informs the basic input/output system 203 to remove the pairing password information, and uses the pairing password information to release the encryption setting on the hard disk device 211. Finally, the basic input The output system 203 removes the pairing password information of the memory device 202 and responds to the processor 201 removal success.

A seventh embodiment of the present invention exemplifies how to cancel the pairing relationship between the electronic device 200 and the base device 210 using the basic input/output system 203. In the sixth embodiment, the electronic device 200 has been connected to the port 212 of the base device 210 via the port 206, and the user has activated the electronic device 200 but has not entered the operating system. At this time, the user operates the electronic device 200 to enter the basic input/output system 203 (for example, pressing the F2 button). In the basic input/output system 203, the user switches to the security setting page to display the password setting state. Next, the user starts the process of unlocking the encryption setting of the hard disk device 211 by selecting an item of the setup menu. In the seventh embodiment, a pair of password reversal programs are executed on the paired password information displayed by the basic input/output system 203 to obtain a set of Master Passwords. Finally, the pairing password information and the universal password are used to unlock the encryption setting on the hard disk device 211, and the pairing password information of the memory device 202 is cleared. In the sixth embodiment, the user does not need to execute the application program by entering the operating system to release the pairing relationship between the electronic device 200 and the base device 210. That is to say, through the method described in the seventh embodiment, the user can enter the operating system (for example, the operating system is faulty), switch to another operating system, or cannot use the fifth embodiment. In the case of the application, the pairing relationship between the electronic device 200 and the base device 210 is released.

Through the device pairing verification method described in the second to seventh embodiments, the pairing relationship between the electronic device 200 and the base device 210 can be increased without adding any hardware cost. Further, the second to fourth embodiments described above The device pairing verification method prevents the hard disk device 211 of the base device 210 from being arbitrarily accessed. Further, the unlocking actions described in the above third and fifth embodiments are all automated, and therefore, the hard disk device 211 is in a protected state in daily use. If the operating system or the hardware of the electronic device 200 is unfortunately damaged, there is still a chance to cancel the encryption setting on the hard disk device 211 by the method of the seventh embodiment to access the stored data in the hard disk device 211.

Since the port 206, the port 208, and the port 212 are connected to the USB interface, the electronic device 200 can support Selective Suspend power management to save power consumption of the USB device. When the electronic device 200 enters the operating system and executes the Selective Suspend power management program, the hard disk device 211 is again locked after entering a preset power management cycle. At this time, the user cannot access the hard disk device 211 and is inconvenient. In the Windows operating system, to solve the above problem, the USB controller must be commanded to stop executing the Selective Suspend power management program, which causes all USB devices to stop performing Selective Suspend power management. As a result, the electronic device 200 cannot simultaneously perform Selective Suspend power management and access to the hard disk device 211. As such, the access to the hard disk device 211 conflicts with the Selective Suspend power management.

In view of this, an eighth embodiment of the present invention exemplifies how the computer system 20 maintains the pairing relationship between the electronic device 200 and the base device 210 in the case of supporting Selective Suspend power management. In the eighth embodiment, during a power management cycle in which the electronic device 200 performs Selective Suspend power management, the processor 201 detects whether a human interface event has occurred in the computer system 20. For example, the processor 201 detects whether there is a keyboard from the base device 210. Input, or detect whether the user touches the screen of the electronic device 200 or the like. When the processor 201 detects that the human interface event occurs in the computer system 20, the processor 201 reads the pairing password information from the basic input/output system 203, and uses the pairing password information to release the locked state of the hard disk device 211. At this time, during the power management period, the hard disk device 211 is not in the locked state, so that the processor 201 does not need to continue the detection and unlocking action. In other words, if the processor 201 has released the locked state of the hard disk device 211, the processor 201 stops detecting the human interface event until the electronic device 200 enters the next power management cycle. The time of the above unlocking action must be less than a predetermined time (for example, 1.5 seconds). Thus, the computer system 20 can balance the "Selective Suspend state is terminated early" and "The hard disk device 211 is temporarily unable to respond". When the computer system 20 enters the next power management cycle, the electronic device 200 executes the Selective Suspend power management program to set the hard disk device 211 again in the locked state. With the method described in the eighth embodiment, the user can operate the computer system 20 to access the hard disk device 211 in the case where the electronic device 200 executes the Selective Suspend power management program.

A ninth embodiment of the present invention exemplifies how the electronic device 200 recognizes the hard disk device 211 to be locked. In the ninth embodiment, a bridge wafer is mounted in each of the bridge 205 and the bridge 207. In the ninth embodiment, the developer writes identification information (e.g., a specific string) into the firmware field of the bridge chip (not shown) on the bridge 205. The identification information is used to inform the processor 201 to identify the port 206 to be connected to the base unit 210. Therefore, after the computer system 20 is booted, the processor 201 transmits the identification information by identifying the complex bridge (for example, the bridge 205 and the bridge 207). The connection port (for example, the connection port 206) for connecting the base device 210 is known. In other words, the processor 201 recognizes whether the bridge has the identification information, and if so, the processor 201 performs an unlock/lock operation on the storage device (e.g., the hard disk device 211) connected to the bridge. Therefore, the identification method of the ninth embodiment described above can selectively protect the data security of the storage device corresponding to the specific bridge. In addition, the identification method of the ninth embodiment only needs to add identification information (for example, a specific string) to the bridge name or the specific firmware field without requiring a customized firmware, and no additional development cost. Through the identification method of the ninth embodiment, the processor 201 can automatically recognize the hard disk device 211 of the base device 210 in all the USB storage devices to perform the above-described second to eighth embodiments on the hard disk device 211. Device pairing verification method.

Figure 3 is a flow chart showing a method for pairing authentication of the device of the present invention in accordance with the ninth embodiment of the present invention. In step S301, the processor 201 actively queries the basic input/output system 203 of the electronic device 200 for the pairing password information. In step S302, the basic input output system 203 reads the pairing password information and responds to the processor 201. In step S303, the processor 201 sets the hard disk device 211 in a locked state when the electronic device 200 enters a power management cycle. In step S304, during the power management period, the processor 201 detects whether a human interface event occurs in the electronic device 200. If yes, the process proceeds to step S305. In step S305, the processor 201 uses the pairing password information to release the locked state of the hard disk device 211, and stops detecting the human interface event. In step S306, the processor 201 determines whether the electronic device 200 enters the next power management cycle. If yes, the process returns to step S302.

Figure 4 is an illustration of a tenth embodiment of the present invention A flowchart of a device pairing authentication method of the invention. In step S401, the processor 201 actively requests the basic input/output system 203 for the pairing password information. In step S402, the basic input/output system 203 reads the pairing password information and responds to the processor 201. In step S403, the processor 201 detects whether the electronic device 200 is connected to the base device 210 and whether the hard disk device 211 is in a locked state. If yes, the process proceeds to step S404. Finally, in step S404, the processor 201 detects that the electronic device 200 is connected to the base device 210, and detects that the hard disk device 211 is in a locked state. At this time, the processor 201 uses the pairing password information to release the hard device. The locked state of the dish device 211.
