A hacker group in Seattle (GHI) years ago attempted to build secure systems on top of compromised hardware. Although different levels of security could be achieved, the overall outcome was No. You cannot build a fully secured system on top of compromised hardware.
A VPS for this exercise counts as ‘compromised’ hardware.
Intel is pushing there “encrypted enclave” which supposedly protects the host from being able to read or write guest memory. However, I have serious doubt as it is a black box system. It also is very problematic when a security issue (or backdoor) is found as your data is basically exposed
Ultimately you are right about this which is sad. I wonder if at some point there could be a zero knowledge cache for https. Maybe double encrypt it and have the client decrypt it fully.
