To avoid insider attacks one cannot rely on access control to protect a database scheme. Encrypting the database is a better option. This paper describes a working prototype of an encrypted database system that allows remote querying over the encrypted data. Experiments with the system show the practical impact of our encoding scheme on storage space and CPU time. Two algorithms, each with two different matching rules, are compared to each other.
