Security Issues in Querying Encrypted Data
[chapter]
2005
Lecture Notes in Computer Science
There has been considerable interest in querying encrypted data, allowing a "secure database server" model where the server does not know data values. This paper shows how results from cryptography prove the impossibility of developing a server that meets cryptographicstyle definitions of security and is still efficient enough to be practical. The weaker definitions of security supported by previous secure database server proposals have the potential to reveal significant information. We
