Designing a database encryption technique for database security solution with cache

A database is a vast collection of data which helps us to collect, retrieve, organize and manage the data in an efficient and effective manner. Databases are critical assets. They store client details, financial information, personal files, company secrets and other data necessary for business. Today people are depending more on the corporate data for decision making, management of customer service and supply chain management etc. Any loss, corrupted data or unavailability of data may seriously affect its performance. The database security should provide protected access to the contents of a database and should preserve the integrity, availability, consistency, and quality of the data This paper describes the architecture based on placing the Elliptical curve cryptography module inside database management software (DBMS), just above the database cache. Using this method only selected part of the database can be encrypted instead of the whole database. This architecture allows us to achieve very strong data security using ECC and increase performance using cache.
