Abstract
Methods, systems, and devices are described herein for delivering protected data to a nested trusted execution environment (TrEE) associated with an untrusted requestor. The nested TrEE may include a trustlet running on top of secure kernel. In one aspect, a targeting protocol head, or other intermediary between a requestor and a key management system or other store of protected data, may receive a request for protected data from a potentially untrusted requestor, an attestation statement of the secure kernel, and a key certification statement. The key certification statement may bind a trustlet public encryption key and a trustlet ID. The targeting protocol head may retrieve the protected data, and encrypt the protected data with the trustlet public encryption key. The targeting protocol head may then send the encrypted protected data to the requestor.
