Four tiers of privacy in cloud computing:
- Four tiers of privacy in cloud computing:
- 1) Cloud apps: couch surfing in someone else's apartment.
- The host can do whatever they want.
- 2) Cloud VMs: renting an apartment.
- The landlord can come in but only in an emergency.
- 3) Trusted Execution Environments: an embassy.
- Snooping would be an act of war.
- 4) ZK Proofs: a volcano lair on a remote island.
- Society would have to have broken down.
- Each tier gives you an order of magnitude better protection.
- The vast majority of the cloud is in tier 1 or 2 today
- Moving most computing to tier 3 would be a massive improvement.
- Tier 4 is overkill for most situations.
- Your family pictures will definitely be safe in the embassy.
