Trusted Execution Environment for Testing

[bjoberg]

Overview

Is it possible to create trusted execution environments (TEE) for testing? I understand that the actual TEE infrastructure can be created by anyone at anytime (e.g. AWS Nitro Enclave); however, it is unclear to me how I can access the decrypted version of the test reports. My organization is not yet ready to fully register with the Privacy Sandbox team, but we still want to create a POC for the functionality associated with: 1) Real-time reporting and 2) Extended Private Aggregation Reporting in FLEDGE

Referencing this document, I would like to test:

To access decrypted versions of the reports, the adtech-operated aggregation service runs an approved version of the aggregation logic in a Trusted Execution Environment (TEE). Decryption keys will only be released to TEEs running an approved version of the aggregation logic.
