Description

In our process we improve the confidentiality on database. We achieve the database security as well as data security. Data is encrypted before the process is started by service provider. Any software-based cryptographic constructs then deployed, for server-side query processing on the encrypted data, inherently limit query expressiveness. We implement the Trusted DB, an outsourced database prototype that allows clients to execute SQL queries with privacy and under regulatory compliance constraints by leveraging server-hosted, tamper-proof trusted hardware in critical query processing stages, thereby removing any limitations on the type of supported queries. We achieve this security based on minimum cost and high performances. Recent trend towards database outsourcing the information, as well as concerns and laws leading data confidentiality, have led to huge importance in enabling secure database services. Preceding approaches to enabling such a service have been based on data encryption, causing a large over-heading query processing. In TrustedDB is an outsourced database prototype that allows clients to execute SQL queries with confidentiality and under regulatory compliance constraints without having to trust the service provider. TrustedDB achieves this by leveraging server-hosted tamper-proof trusted hardware in dangerous query processing stages.
