Abstract

Future aspects of the has turned into a network centric warfare(NCW). Organically combined wired and wireless networks in a variety of cross-of-the-art combat power factor utilization of information and communication technology is a key element of NCW implementation. At used various information in the NCW must be the confidentiality and integrity excellent then quick situation assessment through reliability the real-time processing, which is the core of winning the war. In this paper, NCW is one of the key technologies of the implementation of 128-bit output stream cipher algorithm is proposed. AES-based stream cipher developed by applying modified OFB mode the confidentiality and integrity as well as hardware implementation to the security and real-time processing is superior.

미래전의 양상은 네트워크중심전(NCW: Network Centric Warfare)으로 바뀌고 있으며, 다양한 전력 요소가 유무선 네트워크와 상호 유기적인 연결을 통한 첨단 정보통신기술의 활용이 네트워크중심전의 구현에 핵심 요소라고 할 수 있다. 그리고 네트워크중심전에 사용되는 다양한 정보들은 기밀성과 무결성이 우수하면서 신뢰성 있는 실시간 처리만이 빠른 상황판단을 할 수 있고, 이는 전쟁 승리의 핵심이 된다. 본 논문에서는 네트워크중심전 구현에 핵심 기술 중 하나인 암호 알고리즘으로서 128비트 출력 스트림 암호를 개발했다. 개발한 스트림 암호는 AES를 기반으로 변형된 OFB모드를 적용하여 기밀성과 무결성 그리고 하드웨어로 구현하여 실시간처리와 안전성이 우수하다.
