초록

차세대 전술통신체계인 TICN은 대용량, 고속 및 원거리 우선 통신을 위해 설계되었다. 특히 전장에서의 이동성 보정을 위해 무선 통신이 가능한 애드혹 네트워크 기술 적용을 고려하고 있다. 애드혹 네트워크에서 기밀성, 무결성 및 인증을 보장하기 위한 키 관리 기법은 매우 중요하다. 본 논문에서는 TICN과 같은 전술 애드혹 네트워크의 계층적 특성을 고려한 새로운 하이브리드 키 관리 기법을 제안한다. 즉, 충분한 에너지와 계산능력을 갖춘 상위계층 노드에서는 PKI 기반의 키 관리 기법을 적용하고, 반면 상대적으로 제한된 에너지를 가지는 하위계층에서는 에너지 효율성을 보장하기 위해 위치기반의 인증을 통한 새로운 키 관리 기법을 제안한다.

A next generation military communication system called Tactical Information Communication Network(TICN) is designed to advance into large capacity, high speed, and long distance wireless relay transmission. To support mobility in battlefield, the application of Ad-hoc networking technology to its wireless communication is being considered. In Ad-hoc network, the key management technique is very important to ensure the confidentiality, integrity, and authentication. In this paper, we propose a new hybrid key management scheme considering the hierarchical characteristics of the tactical ad-hoc such as TICN. For upper layer with sufficient energy and computation capability, we apply PKI based key management scheme. For lower layer with restricted resources, we propose a new key management scheme using the location-based authentication to ensure the energy efficiency.
