Abstract
During booting of a computing device, multiple security boundaries are generated. A security boundary refers to a manner of operation of a computing device or a portion of the computing device, with a program executing in one security boundary being prohibited from accessing data and programs in another security boundary. As part of booting the computing device measurements of (e.g., hash values or other identifications of) various modules loaded and executed as part of booting the computing device are maintained by a boot measurement system of the computing device. Additionally, as part of booting the computing device, public/private key pairs of one of the security boundaries is generated or otherwise obtained. Private keys of the public/private key pairs are provided to the one security boundary, and the public keys of the public/private key pairs are provided to the boot measurement system.
