Abstract
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.
