Abstract
A method and apparatus is described herein for emulating a physical trusted platform module (TPM) in a virtual monitor, such as a system management mode (SMM) or a system management interrupt (SMI) transfer monitor (STM). By allowing SMIs during a secure launch, SMM is allowed into the secure launch trust perimeter and a virtual monitor may emulate the structures, behaviors, and protected storage of a physical TMP, such as the storage of cryptographic keys, secure verification, attestation, and other TPM functions.
