Abstract

The present invention teaches a variety of methods for building and searching (102) secure, indexed database tables. Sensitive portio of the database tables and database indexes are encrypted (108), ordered (110) and searched according to Boolean functions arranges work with encrypted data. Also disclosed is a database management system that allows authorized users to build and search encrypted tables.
