Data storage and retrieval is necessary for any organization. A large amount of data leads to data storage, processing and retrieval of the required data. Security is also another big challenge to protect data from unauthorized users. Database security is to protect data from internal and external threats. A legitimate user who has the proper credentials to access the organization’s databases may, over time, send data outside the organizational network through a variety of channels, such as e-mail or crafted HTTP requests that encapsulate data. The database management system software helps monitor the access control mechanism and includes the inside threats using security configuration standards and protocols. We proposed a new security mechanism through encryption to enhance the security mechanism during the storing and retrieval process. This process will help to protect data from a legitimate users. The primary goal is to limit the authenticate users using the Diffusion based cryptography technique. The secondary goal is to encrypt the data while storing and retrieving the process. This can be achieved using the Diffie Hellman key exchange algorithm. The diffusion base encryption approach is the most popular cryptosystem based on the secrecy of the key rather than the secrecy of the algorithm. It is based on kerckoff’s principle. It is best suitable to secure large data storage and retrieval through an encryption mechanism. The proposed system mainly focused on storing data in the database and retrieving data from the database with an encrypted mechanism. The main focus is to secure data from the inside and outside attackers. The key element is to avoid the misuse of data from the database by an outsider.
