Cryptography and Relational Database Management Systems

Security is becoming one of the most urgent challenges in database research and industry, and the challenge is intensifying due to the enormous popularity of e-business. In this paper we study database security from a cryptographic point of view. We show how to integrate modern cryptography technology into a relational database management system to solve some major security problems. Our study shows that cryptographic support is an indispensable ingredient for a modern RDBMS to provide a secure environment for storing and processing huge amount of business data.
