Abstract
본 논문에서는 IoT 환경을 위한 안전한 이동성 관리 기법에 대해서 제안한다. IoT 노드는 저전력 컴퓨터이기 때문에, 오버헤드가 큰 작업들을 대신 수행하는 프록시 노드를 두어 대신 처리하도록 하였다. 기존 MQTT에서 reserved 상태인 필드를 이용해 메시지 타입을 확장하였고 새로운 시퀀스를 제안하였다. 실제 시스템을 구축했고 이를 통해 실험을 진행하였다. encryption에 따른 latency 성능 분석은 보안과 성능 두 가지 측면에 있어서 AES-128일 때 가장 효율적이라는 결과를 도출했으며, loss rate에 따른 latency 성능 분석에서는 Loss Rate 0.14이상부터는 상승폭이 커져 비효율적임을 밝혀냈다.; In this paper, we propose a secure mobility management technique in IoT environment. Since the IoT node is a low-power computer, we propose a system in which the proxy node replaces these processes to reduce the overhead even at low power. In the existing MQTT, we defined the message type considering the mobility by using the reserved field and actually developed and experimented. The latency comparison was performed according to the crypt-method used in this technique, and a delay time of 824 msec was obtained when using AES-128 as the most optimal result. In the analysis of the latency according to loss rate, it is found that if loss rate is higher than 0.14, it is inefficient.
