背景技术 Background technique

当今世界已迈入一个信息蓬勃发展的新纪元,各种由计算器所衍生的信息产品,其快速的发展脚步,不仅缩短了人与人之间在时间上与空间上的距离,且与我们的生活息息相关而不可分离,而随着当前各类信息产品不断地推陈出新,其相关的电源控制技术与省电方法也是不断的研发精进,不可讳言地,未来的计算机设备能否提供人们更方便、更有效、更省电的全方位服务,俨然已成为评价各国信息科技是否领先他国的重要指标之一。 The world has entered a new era of information is booming, all kinds of calculators derived information products, its rapid pace of development, not only shortened the distance between people and the space on time and with our lives and not separable, and with the current information of all kinds continue to introduce new products, its associated power control technology and power saving method is constantly developing sophisticated, it must be said, the future of computer equipment can provide people more convenient and more effective, more energy-efficient full-service, has become an evaluation of whether one of the leading countries in information technology an important indicator of his country.

举例而言,微软公司所推出的Windows XP操作系统,即支持计算机业界的高级配置与电源接口(简称:Advanced Configuration and Power Interface, ACPI)的电源管理技术,允许该操作系统控制计算机和周边装置的电源,而该操作系统中的电源管理功能包含了r休眠模式」和「待命模式J,以下则对r休眠模式」和r待命模式J分别说明两者的动作流程及差异: For example, Microsoft has launched a Windows XP operating system, which is to support the Advanced Configuration and Power Interface computer industry (abbreviation: Advanced Configuration and Power Interface, ACPI) power management technology that allows the operating system to control the computer and peripheral devices power, and the operating system power management features include a sleep mode r "and" standby mode J, the following is a sleep mode to r 'and r J standby mode operation of the process and the differences between the two are:

(A)休目M莫式(Hibernation Model):该操作系统是将一计算机已开启的文件和档案、随M储器及中央处理器的工作状态以压缩影像文件的形式储存到该计算机的一硬盘中,再将该计算机完全关机,当该计算机的电源再被启动时,该搡作系统就会解压缩该压缩影像文件,以恢复原先已开启的丈件和应用禾呈序,让该计算才/li可以i^先前的工作状态中; (A) off the mesh M Morse (Hibernation Model): This is a computer operating system files and files have been opened, with the reservoir and the working state M a central processor in a compressed form to an image file stored in the computer hard disk, and then the computer is completely shut down, when the power of the computer is started again, the system will push for decompressing the compressed image file to restore the original piece is on the husband and application Wo was order, so that the calculation before / li i ^ may be a previous operating state;

(B)待命模式(Standby Model):该操作系统会切断该计算机对周边装置、屏幕、硬盘等硬件组件的供电,以降低该计算机耗电量,但会维持随才踏取存储器(RAM)中的电源供应,这样被开启的文件和应用程序的工作状态^^呆存于该随机存IM^储器之中,由于,该操作系统并不需压缩影像文 (B) standby mode (Standby Model): The operating system will cut off power to the peripheral device to the computer, screen, hard disk and other hardware components of the computer to reduce power consumption, but it will remain with the pedaling access memory (RAM), power supply, the operating state thus opened files and applications stored in the ^^ stay in the random access IM ^ reservoir, because the operating system does not need compressed video packets

中,故,待命^^莫式可比休目R^莫式更快速地恢复到先前的工作状态。 In it, than the stand-off mesh Mohs' ^^ R ^ Mohs more quickly restored to its previous operating state.

另外,若该操作系统被使用者设置一系统密码,则从「休眠模式」和「待命模式J欲恢复到先前的工作状态,则需先输入正确的系统密码,该操作系统才会恢复到先前的工作状态。而计算机的基本输A/输出系统(BIOS),是该计算机被启动时,该计算机的中央处理单元(CPU)利用它来开启计算机的系统,它同时管理计算机操作系统和外围装置,如:硬盘、视频接收器、 键盘、鼠标和打印才几.,.等之间的数据流,因此,若该基本输入/输出系统被任意地修改,将可能导致无法正常开;fe/L,故,为避免防止他人随意修改BIOS 设置,以保证计算机的正常运行,BIOS并提供密码设置功能,该密码设置功能大致分为开机密码(Power On Password)、超级用户密码(Super Visor Password)和硬盘密码(Hard Disk Password)等。 In addition, if the operating system is set up a system password users, from the "sleep mode" and "standby mode J to be restored to its previous working state, you need to first enter the correct password system, the operating system will be restored to its previous operating state while the basic computer input a / output system (the BIOS), when the computer is started, the central processing unit of the computer (CPU) to use it to turn the system on a computer, which manage a computer operating system and peripheral devices , such as: a hard disk, a video receiver, a keyboard, a mouse, and print only a few, like the flow of data between, and therefore, if the basic input / output system be optionally modified, may result in not properly open; fe / L therefore, in order to avoid to prevent others to freely modify the BIOS settings to ensure the normal operation of the computer, BIOS setup functions and provide the password, the password setting function is broadly divided into power-on password (Power On password), the superuser password (super Visor password) and hard disk password (hard Disk password) and so on.

此外,当该BIOS被设置硬盘密码后,该硬盘每次重新给电后,都必须 In addition, after the BIOS hard drive password is set, the hard disk again after each feeding, must

:命 :Life

模式」时,该计算机对周边装置、屏幕、硬盘等硬件组件的供电将会被切断, When mode ", the computer will be cut off power supply to peripheral devices, screens, hard drives and other hardware components,

因此,该计算机在r待命模式J下欲恢复到先前的工作状态,该计算机会要求再输入硬盘密码,故,有些计算机为避免在r待命模式」欲恢复到先前的工作状态,该计算机会要求输入系统密码及硬盘密码等程序,造成使用者的困扰,会在该计算机第一次开机时,将该硬盘密码储存在该计算机所设的一互才卜金属氧4b物半导体(Complementary Metal-Oxide Semiconductor,简称: CMOS)内,而若该计算机在r待命模式」下欲恢复到先前的工作状态,该 Therefore, the computer in the r standby mode J to be restored to its previous working state, the computer will be asked to re-enter the hard disk password, so that some computers to avoid r standby mode "To revert to a previous working state, the computer will ask enter the system password and hard disk password and other procedures, causing distress to the user, when the computer will boot first time, the password is stored in the hard disk provided in a computer only cross Bu 4b metal oxide semiconductor (Complementary metal-oxide Semiconductor, short: CMOS) inside, and if the computer is in standby mode r "to be restored to its previous working state, the

重新把密码输入到硬盘中,才可继续使用硬盘,且如前述该计算机在「待命计算机可自动从所述互补金属氧化物半导体取出所迷硬盘密码,并填入所迷硬盘中,让使用者不用再输入所述硬盘密码,但该计算机可能在使用的过程中,更改该硬盘密码,因此,该计算机在每次开机时,都必需再重新将该硬盘密码写入该互补金属氧化物半导体中。 Re-enter the password to the hard disk, to continue using the hard disk, and as the computer can automatically remove the hard metal oxide semiconductor password from the fans complementary to "standby computer, a hard disk and fill the fans, so that the user do not have to enter a password to the hard disk, but the computer may be used in the process, change the hard disk password, therefore, the computer at each boot, the hard disk are necessary to re-write the password complementary metal oxide semiconductor .

但是,该互蜂险属氧化物半导体的储存容量及读写次数有限,若该计算机在每次开机时,都必需再重新将硬盘密码写入该互补金属氣化物半导体中,则该互4峻属氧化物半导体被读写的次数将会快速地衰减,不符合互补金属氧化物半导体的使用效益,此外,该互补金属氧化物半导体的存取方式, 几乎为一般计算机使用者所熟悉,甚至是网络上也公开了许多该互补金属氧化物半导体的存取方式的文献,因此,该互补金属氧化物半导体所存放的数据是很容易被外人所窃取,进而破解取得所述硬盘密码,故,如何在不需将所述硬盘密码存放在该互补金属氧化物半导体中,减少该互补金属氧化物半导体被读取的次数,且避免该硬盘密码被窃取,相信是业者及使用者所乐见的。 However, this is a limited risk of mutual bee storage capacity and the oxide semiconductor read and write times, if the computer at each boot, the hard disk are necessary to re-write the password semiconductor, the mutual complement of the metal vapor Jun 4 read the number of oxide-semiconductor will be quickly attenuated, does not meet the efficiency in the use of complementary metal oxide semiconductor, in addition, the complementary metal oxide semiconductor access mode, almost general computer users are familiar with, or even discloses many network access mode of the complementary metal oxide semiconductor literature, therefore, the complementary data stored in metal oxide semiconductor is easily stolen by an outsider, thereby obtaining the hard disk password cracking, therefore, how in the hard disk password need not be stored in the complementary metal oxide semiconductor, which reduce the number of complementary metal oxide semiconductor is read, and avoid the hard disk password is stolen, believed to be the industry and users would like to see.
