Abstract
A system for confirming a computing environment includes a remote computing device connected by a communication network to a computing device. The remote computing device generates a nonce, or number used once, and executes an attestation function to determine an attestation measurement value based on the contents of the memory of the remote computing device. The nonce is transmitted by the network to the computing device, which uses the nonce to execute the attestation function based on the contents of the memory of the computing device and determine an attestation measurement value. This attestation measurement value is transmitted to the remote computing device. If the attestation measurement values match, the computing device is designated as trusted. If the attestation measurement values mismatch, the computing device is designated as untrusted.
