TrustedDB: A Trusted Hardware based Database with Privacy and Data Confidentiality

Summary: TrustedDB: outsourced DB using tamper-proof hardware to enforce privacy in query processing. Keeps SQL expressiveness; even with hardware overhead, per-query cost is orders of magnitude lower than software-only approaches, validated on real hardware.
