    • Secure variable/image storage and access schemes for storing data in non-volatile stores. Firmware-based interfaces are provided to support secure storage of data, such as asset management data and executable images, on platforms in a manner that prevents access to any entity other than the principle that originally stored the data. In one embodiment, an extension to the Extensible Firmware Interface (EFI) variable storage scheme is disclosed. In another embodiment, a management chip that is not present on the platform is emulated by firmware such that the management chip appears to be present to entities accessing a third-party storage area of a non-volatile store.
    • 用于将数据存储在非易失性存储中的安全变量/映像存储和访问方案。 提供了基于固件的接口,以支持在平台上以数据的安全存储(例如资产管理数据和可执行映像)的方式,以防止访问除最初存​​储数据的原理之外的任何实体。 在一个实施例中,公开了对可扩展固件接口(EFI)变量存储方案的扩展。 在另一实施例中,平台上不存在的管理芯片由固件进行仿真,使得管理芯片看起来存在于访问非易失性存储区的第三方存储区域的实体。
