Abstract
Methods and systems for increasing the security or trust associated with an untrusted device are provided. For example, a trusted hardware component may send a request to the untrusted device. The request may indicate one or more challenges to be performed by a secure application executing on the untrusted device. The trusted hardware component may determine an expected response to the one or more challenges. The expected response may be determined at the secure hardware component based on an expected configuration of the untrusted device. The trusted hardware component may receive a response to the request from the untrusted device. The trusted hardware component may determine a security status of the untrusted device based on the expected response and the received response.
