Abstract
System and method for performing a remote attestation for creation of a trusted execution environment (TEE) using a virtual secure enclave device running in a virtualized environment utilizes a trusted bootloader appliance in a TEE virtual computing instance, which is created in response to a request for a TEE from a software process running in the system. The trusted bootloader appliance manages the provisioning of a TEE in the TEE virtual computing instance for the software process. The remote attestation includes performing a first stage attestation on the trusted bootloader appliance by a hardware platform of the computer system and performing a second stage attestation on the provisioned TEE by the trusted bootloader appliance.
