EVALUATING ENCRYPTION TECHNIQUES FOR C4I SYSTEM

Abstract

C4I system (Command, Control, Communication, Computer and Intelligence) represents a real instance of complex System of Systems (SoS) application that make intensive use of IT and communications. This makes C4I systems more attractive to malicious attacks. Therefore there is a pressing need to integrate a sophisticated encryption technique into the C4I system to secure the exchange of sensitive data between the C4I system and its environment. The purpose of this paper is to evaluate three popular encryption techniques and select the one judged the best for providing optimal secure data and image exchange between a C4I system and its environment. The evaluation has been conducted based on a number of critical information security related criteria using a MCDM (Multi Criteria Decision Making) method.
