    • A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.
    • 这里描述了用于安全地引导电子设备中的软件组件以建立操作环境的方法和装置。 根据本发明的一个方面,软件组件将按顺序执行,以便建立设备的操作环境。 对于每个软件组件,执行安全代码以使用嵌入在设备的安全ROM(只读存储器)中的一个或多个密钥来验证和验证与每个软件组件相关联的可执行代码图像,以及一个或多个硬件配置设置 装置。 每个软件组件的安全代码包括用于认证和验证与每个软件组件相关联的可执行代码映像的通用功能。 响应于成功地认证和验证可执行代码图像,然后在设备的主存储器中执行可执行代码图像以启动相关联的软件组件。
