Executive Summary

In this paper, the authors have developed a new orthogonal cryptographic system for database security that has used both cellular automata and Hash algorithm. Their algorithm consists of two different parts; encryption/decryption of database tables as well as the generation of the authentication Tag for the activation of the attack alarm for the database tables while it is unlocked and in protected mode but it has been accessed by the illegal users. Their proposed orthogonal cryptosystem is considered to be symmetric algorithm and uses a common key for both encryption and decryption processes as oppose to the asymmetric one that requires two keys, private and public keys.
