Abstract
Responsive to a request for an encrypted confidential virtual machine (CVM) disk image, an unencrypted CVM disk image, an image signature, and a public key associated with the image signature is obtained. The CVM disk image is encrypted to produce an encrypted CVM disk image. Full disk encryption (FDE) is applied against the encrypted CVM disk image to obtain an FDE header. A concatenation of the image signature, the public key associated with the image signature, and the FDE header is signed to obtain an image encryption service (IES) signature. The IES signature and associated certificate chain are written to the extensible firmware interface system partition (ESP) of the encrypted CVM disk image.
