Abstract
Methods, apparatus, systems and machine-readable storage media to enable fast boot of secure and unsecure environments in a computing system are disclosed. Root of trust hardware is used to provide dynamic root of trust measurements of various virtual machines, operating systems, and application environments within the computing system. In an example, a trusted application for a trusted environment is initiated with a fast boot process, with use of a secure enclave accessed by an operating system and virtual machine. The root of trust hardware is used to perform dynamic integrity measurements of a second virtual machine and an untrusted application, to later initiate this untrusted application securely after verification of the integrity measurements. Further uses and coordination of dynamic root of trust measurements and application execution, booting, and security verification processes are also described.
