The invention relates to hardware cipher accessing method; especially a protection password that refers to a kind of hardware with a computing machine; before this computing machine is desired to enter into standby from mode of operation; be stored in the set random access memory of this computing machine; enter into standby again; and before this computing machine desired to return to mode of operation from standby, this computing machine can be obtained described hardware encryption from described random access memory, to reactivate this hardware.
Background technology
The world today has marched toward the new era that information is flourish, various information products of deriving by counter, it develops step fast, not only shortened interpersonal in time with the space on distance, and it is closely bound up and inseparable with our life, and along with current various information product is constantly weeded out the old and bring forth the new, power supply control technology that it is relevant and electricity saving method also are that constantly research and development progress greatly, can not dare not or would not speak up ground, can following computer equipment provide people more convenient, more effective, the more all-around service of power saving has just like become evaluation various countries Information technology and whether has taken the lead one of important indicator of other country.
For example, the Windows XP operating system that Microsoft released, promptly support the ACPI of computer circle (to be called for short: Advanced Configuration and Power Interface, ACPI) power management techniques, allow the power supply of this operating system control computer and peripheral device, and the power management function in this operating system has comprised " park mode " and " standby ", with next motion flow and the difference that " park mode " and " standby " is illustrated both respectively:
(A) park mode (Hibernation Model): this operating system is that the duty of file that a computing machine has been opened and archives, random access memory and central processing unit is stored in the hard disk of this computing machine with the form of compressing image file, again this computing machine is shut down fully, when the power supply of this computing machine is activated again, this operating system this compressing image file that will decompress, this computing machine can be entered in the previous duty for file and application program to recover originally to have opened;
(B) standby (Standby Model): this operating system can be cut off this computing machine to peripheral device, screen, the power supply of nextport hardware component NextPorts such as hard disk, to reduce this computing machine power consumption, but can keep the power supply supply in the random-access memory (ram), the file that is unlocked like this and the duty of application program can be stored among this random access memory, because, this operating system does not need the compressing image file, and the file that is unlocked and the duty of application program still are stored among this random access memory, so the comparable park mode of standby returns to previous duty more quickly.
In addition, if this operating system is provided with a system password by the user, then desire to return to previous duty from " park mode " and " standby ", then need the correct system password of input earlier, this operating system just can return to previous duty.And the basic input/output of computing machine (BIOS), be that this computing machine is when being activated, the CPU (central processing unit) of this computing machine (CPU) utilizes it to open system for computer, it is supervisory computer operating system and peripheral unit simultaneously, as: hard disk, video receiver, keyboard, mouse and printer ... the data stream between waiting, therefore, if this basic input/output is at random revised, may cause can't normal boot-strap, so, for avoiding preventing that other people hack BIOS is provided with, to guarantee the normal operation of computing machine, BIOS also provides the password setting function, and this password setting function roughly is divided into startup password (Power On Password), supervisor password (Super VisorPassword) and harddisk password (Hard Disk Password) etc.
In addition, after this BIOS is set up harddisk password, after this hard disk is given electricity at every turn again, all must be input to password in the hard disk again, just can continue to use hard disk, and this computing machine is when " standby " as described above, this computing machine is to peripheral device, screen, the power supply of nextport hardware component NextPorts such as hard disk will be cut off, therefore, this computing machine desires to return to previous duty under " standby ", this computing machine can require to import harddisk password again, so, some computing machine desires to return to previous duty for avoiding at " standby ", this computing machine can require input system password and harddisk password supervisor, cause user's puzzlement, can be when this computing machine be started shooting for the first time, this harddisk password is stored in the set complementary metal oxide semiconductor (CMOS) of this computing machine (Complementary Metal-Oxide Semiconductor, be called for short: CMOS), and if this computing machine desires to return to previous duty under " standby ", this computing machine can take out described harddisk password from described complementary metal oxide semiconductor (CMOS) automatically, and insert in the described hard disk, allow the user need not import described harddisk password again, but this computing machine may be in the process of using, change this harddisk password, therefore, this computing machine all must write this harddisk password in this complementary metal oxide semiconductor (CMOS) when each start more again.
But, the storage volume of this complementary metal oxide semiconductor (CMOS) and read-write number of times are limited, if this computing machine is when each start, all must harddisk password be write in this complementary metal oxide semiconductor (CMOS) again again, then the number of times read and write of this complementary metal oxide semiconductor (CMOS) will be decayed apace, do not meet the utilization benefit of complementary metal oxide semiconductor (CMOS), in addition, the access mode of this complementary metal oxide semiconductor (CMOS), being almost general computing machine user is familiar with, or even the document of the access mode of many these complementary metal oxide semiconductor (CMOS)s also disclosed on the network, therefore, the stored data of this complementary metal oxide semiconductor (CMOS) are to be easy to be stolen by the stranger, and then crack and obtain described harddisk password, so, how described harddisk password is left in this complementary metal oxide semiconductor (CMOS) not needing, reduce the number of times that this complementary metal oxide semiconductor (CMOS) is read, and avoid this harddisk password to be stolen, believe it is that dealer and user find pleasure in and see.
