Abstract: A secure terminal configured to support a trusted execution environment that utilizes policy enforcement to filter and authorize transmissions received from a host device and destined for a remote device. Upon receiving a transmission from the host device, the secure terminal verifies that the instruction, message, or request contained within the transmission satisfy parameters set by a policy. If the transmission satisfies the parameters, then the secure terminal signs the transmission with a key unique to the trusted platform module associated with the secure terminal and forwards the signed transmission to the remote device. If the transmission fails one or more parameters within the policy, a message that details the instruction or operation contained within the transmission is exposed to a user at an output device, in which the user can authorize or reject the transmission using an input device.
