Abstract
A device is configured with a trusted platform module (TPM) executing in a trusted execution environment (TEE). Software/firmware updates, user data, applications, etc. are pushed to the device as a payload. The payloads contain a sealed container (e.g., the software/firmware update, user data, applications, etc.), one or more policies, and one or more provisioning code segments corresponding to the one or more policies. The policies are checked by the TPM of the device. If the measurement of the one or more provisioning code segments satisfy the one or more policies, then the sealed container is unsealed by the TPM and released to the device.
