Abstract
Techniques are described herein that are capable of provisioning a trusted execution environment (TEE) based on (e.g., based at least in part on) a chain of trust that includes a platform on which the TEE executes. Any suitable number of TEEs may be provisioned. For instance, a chain of trust may be established from each TEE to the platform on which an operating system that launched the TEE runs. Any two or more TEEs may be launched by operating system(s) running on the same platform or by different operating systems running on respective platforms. Once the chain of trust is established for a TEE, the TEE can be provisioned with information, including but not limited to policies, secret keys, secret data, and/or secret code. Accordingly, the TEE can be customized with the information without other parties, such as a cloud provider, being able to know or manipulate the information.
