Encryption of Blob Field Content Using AES Algorithm on CBT (Computer Based Testing) System

Juli Rejito, Deni Setiana, Rudi Rosadi

Implementation of information technology especially in CBT (Computer-Based Test) is starting to use. Confidentiality matter stored in the database becomes the main thing that must be considered because the questions used in the test should not publish both from test participants (clients) as well as from a database manager (administrator). In this paper will be presented one alternative security solutions matter stored in blob field database that contains the encoded image, so the original content that matter will only be read when using the actual application. Technical encryption used to take advantage of symmetric encryption that is raised in the application form entry question bank as tools incorporate a matter also functions for encryption of content matter, on the other hand, the used of applications CBT used by the user to work also functions as the decrypted content question. Proof of the encryption result is shown with direct access to blob field matter content stored in the database using database access interface.
