Abstract
An apparatus to facilitate broadcast remote sealing for scalable trusted execution environment provisioning is disclosed. The apparatus includes an execution platform for secure execution of a workload of the tenant to: perform an attestation of the execution platform with a cloud service provider (CSP); receive a command from the CSP to create a group of trusted execution platforms; create the group comprising the execution platform; confirm an existence and a status of the group based on the attestation of the execution platform and based on a current group status of the group; report a trusted computing base (TCB) of the first execution platform to other member execution platforms of the group, wherein the other member execution platforms satisfy minimum TCB requirements of the group; and execute an encrypted workload of the tenant using a group private key, wherein the workload of the tenant is encrypted using a group public key.
