A method, apparatus, system and computer program product are provided for booting up a system using a secure boot framework. In particular, a secure boot mechanism (i.e., a mechanism that enforces that only authenticated programs and/or events are executed on a particular platform) is provided that has an unlimited number of authorized boot configurations, while requiring only a minimal amount of secure/confidential storage. The secure boot mechanism further provides for the separation of run-time and management functionality, which allows other authorization mechanisms to be plugged-in later on. In addition, the authorized secure boot configurations (i.e., the definition of the secure boot state) can be kept in insecure storage, such as a system disk (e.g., flash memory). Finally, the disclosed secure boot mechanism is further beneficial because it builds upon existing TCG techniques, causing it to require minimal implementation where TCG techniques are implemented. |
