TrustedDB is an outsourced database prototype that allows clients to execute SQL queries
with privacy and under regulatory compliance constraints without having to trust the service
provider. TrustedDB achieves this by leveraging server-hosted tamper-proof trusted
hardware in critical query processing stages. TrustedDB does not limit the query
expressiveness of supported queries. And, despite the cost overhead and performance
limitations of trusted hardware, the costs per query are orders of magnitude lower than any …

Traditionally, as shortly as confidentiality becomes a priority, data are encrypted before
outsourcing to a service supplier. Any software-based cryptographic constructs then
deployed, for server-side question process on the encrypted information, inherently limit
question quality. Here, Trusted DB has been introduced, an outsourced database prototype
that allows client to execute SQL queries with privacy and beneath restrictive compliance
constraints by leverage server-hosted, tamper-proof trusted hardware in important question …
