초록

무선 네트워킹과 소형화 기술의 발전은 고정된 기반시설이 없는 열악한 환경에서도 초소형의 센서 노드들을 무작위 배치하여 애드혹 네트워킹을 통해 순간적으로 네트워크 인프라를 구축하고 긴밀한 협동 작업을 통해 복잡한 환경감지를 가능하게 하는 센서 네트워크의 개발을 이루어냈다. 각 센서 노드들은 매우 제한적인 능력을 가지고 있지만 이들의 협동작업은 마치 미세한 신경세포 조직이 상호작용하여 동물의 신체활동을 가능하게 하듯이 기존의 네트워킹이나 컴퓨팅에서는 불가능했던 많은 응용들을 가능하게 하여 우리의 생활환경을 스마트한, 지능적인 환경으로 만들어 줄 수 있다. 본 고에서는 이러한 센서 네트워크의 기존 네트워크와의 차별화되는 특징 및 응용에 따른 다양한 보안이슈와 최신 보안기술 연구동향들을 살펴보기로 한다.
