Abstract

Systems and methods for provisioning a sovereign cloud root certificate, retrieve, during a boot process of a sovereign cloud, a root certificate from a first source; measure a cryptographic measurement of the root certificate in a Trusted Platform Module (TPM) of the sovereign cloud, which is stored in a Platform Configuration Register (PCR) of the TPM; generate a Certificate Signing Request (CSR) including the TPM-stored measurement for a leaf certificate based on the PCR; transmit the CSR to a certificate authority for verification; wherein the CSR is forwarded to a Hardware Attestation Service (HAS) for attestation; receiving an attestation result at the certificate authority, the attestation result indicating whether the CSR is valid; and based on the attestation result, receive by the sovereign cloud, the leaf certificate when the attestation result is positive, or a rejection of the CSR when a discrepancy is detected.
