摘要： A method for protecting a password of a computer having a non-volatile memory is disclosed. A password is stored in a non-volatile memory of a computer. The computer is then transitioned to a power saving state. In response to a detection of an unauthorized access to the non-volatile memory during the power saving state transition, a password input is requested from a user. The computer returns to a power-on state from the power saving state when there is a success in authentication of the input password.

摘要： An information processing apparatus includes a Basic Input Output System (BIOS) memory which stores a BIOS program, a management information memory which stores management information in which each BIOS function is associated with an expiration date of the BIOS function and a state of the BIOS function; and a processor. The processor executes a BIOS management process which, when a date acquired from a clock has passed the expiration date stored in the management information memory, disables the BIOS function corresponding to the expiration date and changes, to an invalid state, the state of the BIOS function corresponding to the disabled BIOS function in the management information.

摘要： A set of variables referred to by unified extensible firmware interface (UEFI) firmware is restored. The UEFI firmware stored in a read-only memory (ROM) is firstly executed after power-up. The UEFI firmware writes a variable set related to boot, into a variable area. As an operating system (OS) also writes a set of variables into the variable area, the boot-related variable set may be altered. The variable set is saved into a prescribed area, such as a universal serial bus (USB) memory key, when the computer boots normally. If alteration of the variable set in the reference area is detected during a boot of the computer, the variable set in the reference area is replaced with the saved variable set. The variable set alteration may be detected using a detection flag which is set immediately after a boot is started and reset immediately before an OS is loaded.
摘要翻译：由统一的可扩展固件接口（UEFI）固件引用的一组变量被恢复。存储在只读存储器（ROM）中的UEFI固件首先在加电后执行。 UEFI固件将与引导相关的变量集写入可变区。由于操作系统（OS）还将一组变量写入变量区域，因此引导相关变量集可能会被更改。当计算机正常启动时，变量集保存到规定的区域，如通用串行总线（USB）存储器密钥。如果在引导计算机期间检测到参考区域中设置的变量的变化，则将参考区域中设置的变量替换为保存的变量集。可以使用在启动开始之后立即设置的检测标志来检测变量集改变，并且立即在OS被加载之前重置。

摘要： A computer is made usable in a short time using a fingerprint authentication device. When a fingerprint authentication device performs authentication successfully, the fingerprint authentication device sends a startup signal to a power controller via a line. The power controller controls a DC/DC converter to supply power to devices. The fingerprint authentication device sets whether normal boot or fast boot that is completed in a shorter time than the normal boot is successful, in a register via a line. In the fast boot, initialization of a USB interface of a line and password input by a user are skipped, and a BIOS accesses a system by single sign-on using a password stored in a secure area.

摘要： A laptop computer includes a processor that executes an operating system, an embedded controller, in communication with the processor, that controls hardware elements within the laptop computer independently of the processor, and a wireless tag unit, embedded within the laptop computer, that is readable and writable with takeout detection information via wireless communication. The takeout detection information indicates that the laptop computer has been taken out from a use permissible location. The embedded controller is programmed to directly communicate with the wireless tag unit to determine whether the takeout detection information has been written on the wireless tag, and upon determining that the takeout detection information has been written on the wireless tag, assert a signal to the processor to restrict at least some functionalities of the processor.

摘要： For validating computing device firmware, systems, apparatus, and methods are disclosed. The apparatus includes a processor, and a memory that stores code executable by the processor, the code including code that acquires a firmware manifest for locally stored firmware, authenticates a digital signature of the firmware manifest, and validates contents of the locally stored firmware using the firmware manifest. The apparatus may also include code that generates a local firmware manifest from the firmware, wherein validating the contents of the firmware includes comparing the local firmware manifest to the firmware manifest. In certain embodiments, the apparatus may indicate, to a user, one of success and failure of the firmware validation. The firmware manifest may be a location-specific firmware manifest corresponding to a geographical location of the apparatus and/or computing device including the locally stored firmware.

摘要： A portable computer capable of protecting an encryption key that is sent out to a disk drive after a preboot process has ended is disclosed. The portable computer includes a disk drive for encrypting a volume as a whole, and for decoding data at the volume in response to a receipt of an encryption key from a system. The portable computer also includes a key transfer mechanism, a tamper detection mechanism and a protecting mechanism. In response to a boot process starting from a power-off state, the key transfer mechanism automatically sends the encryption key to the disk drive. The tamper detection mechanism detects a physical tampering of the disk drive. In response to a detection of a physical tampering by the tamper detection mechanism, the protecting mechanism prevents an operation of automatically sending the encryption key to the disk drive by the key transfer mechanism.
