摘要:
A system comprises a basic-input-output-system (“BIOS”), a disk drive, and a security system configured to prevent unauthenticated access to the disk drive. For each of at least two users out of a plurality of users, the BIOS authenticates the user based on the user's token. The BIOS also accesses secured data based on the authentication, and provides the secured data to the security system without input from the user.
摘要:
A computer-readable storage medium containing software that, when executed by a processor, causes the processor to implement a basic input/output system (BIOS). The BIOS comprises instructions that implement a BIOS core, instructions that implement a user authentication and enforcement engine (AEE), and instructions that implement an extensible interface to a preboot authentication module.
摘要:
Unlocking a storage device including identifying a platform configuration register value in response to a computing machine powering on, configuring a security component to seal an authorization based on the platform configuration register value and storing a sealed authorization onto non-volatile memory, and unlocking the storage device in response to the computing machine resuming from a sleep state and unsealing the sealed authorization with the security component from the non-volatile memory.
摘要:
A portable device comprise non-volatile storage. The non-volatile storage comprises a basic input/output system (BIOS) setting. The BIOS setting is applied from the portable device onto a system to which the portable device can be coupled.
摘要:
A computer system is provided that comprises a processor and a Basic Input/Output System (BIOS) accessible to the processor. During a boot process, the BIOS determines an integrity measurement for the computer system and modifies the integrity measurement based on a user authentication.
摘要:
A computer system includes an authentication service running in a virtual machine. The authentication service uses the hardware components of the computer system in performing a user authentication process and responds to a remote call from another virtual machine by performing the user authentication process and returning a result.

摘要:
A system comprises a first operating environment and a second operating environment. The first and second operating environments exchange information in encrypted form using a shared encryption key (K3). The first and second operating environments cooperate to change said encryption key K3 using another shared encryption key (K4). The encryption key K4 is changed upon the encryption key K3 being changed.
