Abstract
A virtualized system that is capable of executing a computation that has been identified as a repeatable computation and recording various representations of the state of the computing environment throughout the execution of the repeatable computation, where the state of the computing environment can be cryptographically signed and/or verified using a trusted platform module (TPM), or other cryptographic module. For example, a TPM embedded in the host computing device may generate a hash measurement that captures the state of the repeatable computation at the time of the computation. This measurement can be digitally signed using one or more cryptographic keys of the TPM and recorded for future use. The recorded state can subsequently be used to repeat the computation and/or determine whether the computation was repeated successfully according to certain defined criteria.
