    摘要： A system, method, and program product is provided that initializes a computer system using an initialization process that identifies secrets that were stored in memory and not scrubbed during a prior use of the computer system. During the initialization process, one or more secret indicators are retrieved that identify whether one or more secrets were scrubbed from the computer system's memory during a previous use of the computer system. If the secret indicators show that one or more secrets were not scrubbed from the memory during the prior use of the computer system, then the initialization process scrubs the memory. On the other hand, if the secret indicators show that each of the secrets was scrubbed from the memory during the prior use of the computer system, then the memory is not scrubbed during the initialization process.

    摘要翻译： 提供了一种系统，方法和程序产品，其使用识别存储在存储器中并且在先前使用计算机系统期间不被擦除的秘密的初始化过程来初始化计算机系统。 在初始化过程中，检索一个或多个秘密指示符，其识别在先前使用计算机系统期间是否从计算机系统的存储器擦除了一个或多个秘密。 如果秘密指示器显示在计算机系统的先前使用期间没有从存储器擦除一个或多个秘密，则初始化过程擦除存储器。 另一方面，如果秘密指示器显示在计算机系统的先前使用期间从存储器擦除了每个秘密，则在初始化过程期间不擦除存储器。

    摘要： An apparatus, system, and method are disclosed for authentication of a core root of trust measurement chain. The apparatus for authentication of a CRTM chain is provided with a plurality of modules configured to carry out the steps of retrieving a decryption key from a predetermined location on the device selected for authentication, decrypting an authentication signal using the decryption key, and communicating the decrypted authentication signal to a user. In the described embodiments, these modules include a retrieval module, a decryption module, and a communication module. Beneficially, such an apparatus, system, and method would reliably verify that a link in the CRTM chain has not been corrupted, modified, or infected with a computer virus. Specifically, such an apparatus, system, and method would enable verification that the hypervisor has not been corrupted, modified, or infected with a computer virus.

    摘要： An approach is provided that receives a user identifier from a user of the information handling system. The user identifier can include a username as well as a user authentication code, such as a password. Hardware settings that correspond to the user identifier are retrieved from a nonvolatile memory. Hardware devices, such as ports (e.g., USB controller), network interfaces, storage devices, and boot sequences, are configured using the retrieved hardware settings. After the hardware devices have been configured to correspond to the identified user, an operating system is booted.

    摘要： An apparatus, system, and method are disclosed for quiescing a boot environment. A reservation module reserves a portion of a first storage device. A store module stores an update boot image to the reserved portion. A detection module detects the update boot image stored on the first storage device when the computer boots and executes the update boot image in place of a standard boot image in response to detecting the update boot image. The update boot image places a computer in a known quiescent state.
