Using Record Level Encryption for Securing Information in Classified Information Systems

Information technology (IT) systems have great potential to improve the efficiency and methods of operation in each government organization, providing added convenience and flexibility. Currently, most of government law enforcement agencies have digitized their methods of work by advancing their user services. With this new approach, have come new threats, therefore, it is necessary to develop and implement standard policies to enhance information security and privacy on all classified information systems. In this paper a novel solution is presented for protection of information up to the record level encryption by applying the Advanced Encryption Standard (AES) algorithm using derived symmetric master key. The master key is unique per each record and is calculated in the client application. The uniqueness of the derived master key is assured by applying the exclusive or operation of the key of each record and the unique key of the client. Furthermore, this paper includes a critical approach on existing cryptographic methods and proposes additional methods to protect information, such us authentication, access control, and audit.
