... PIM-Enclave design retrofits the generalized baseline PIM design to support confidential computing. Figure 2 shows the overall design of PIM-Enclave with the proposed modifications. Key storage containing the root endorsement key (EK) and ROM are added to service attestation and loading requests from the host enclave. ...
