English Abstract

The research is simply a security generator method for Building Data Base.

The system designed h a security interface system between user and a Data Base : The system consists of the following major parts A- Specification Part : Which is a method to describe either data base or relation? base which we need a security to protect them, and to determine the type of relation among data.

B- Cipher Part : In this part, we can use many ideas applied in cryptography method, which are called public key or hit-manipulation ciphers (BMC).

This part consists of two major types 1- ACS : Cipher the data base or the base of certain data relation automatically by depending on a list represents comparison between the concluded solutions and selecting the -best ones according to complexity degree, key easiness, secret grade, correspondence speed: storage availability, error probability, data pressure, and changeability.

2- OCS : This part is recognized by its ability of selective ciphering to be more suitable for application.

This type of ciphering provides the ability of interaction between the expert user and present solutions depending on his experience without system interruption.

Selective ciphering is divided into three levels according to the ability of dealing with the present ciphering ways for mote security.

C- Decipher Part : Which is the process of transforming cipher text into plaintext.
