무인기 기반의 IoT 네트워크에서 효율적인 데이터 수집 및 분배를 위해서는 클러스터 구조의 활용이 필요하며, 이 구조 하에서 데이터 수집을 안전하게 하기 위해서는 클러스터 헤드(Cluster Head: CH)들의 선출을 안전하게 수행하는 것이 필수적이다. 본 고에서는 먼저 무인기 기반의 IoT 네트워크에서 안전한 데이터 수집을 위한 CH 선출 보안 기술의 요구 특성을 소개한다. 다음으로, 기존의 CH 선출 보안 기술들의 동작에 대해 설명하고, 그들의 보안성을 앞서 소개한 요구 특성에 기반하여 비교한다. 마지막으로, 소개된 CH 선출 보안 기술들의 활용 방안을 제시한다.
