Abstract

Recently, the Internet of Things (IoT), which has been applied to various industrial fields, is constantly evolving in the process of automation and digitization. However, in the network where IoT devices are built, research on IoT critical information-related data sharing, personal information protection, and data integrity among intermediate nodes is still being actively studied. In this study, we propose a blockchain-based IoT critical information management technique that is easy to implement without burdening the intermediate node in the network environment where IoT is built. The proposed technique allocates a random value of a random size to the IoT critical information arriving at the intermediate node and manages it to become a decentralized P2P blockchain. In addition, the proposed technique makes it easier to manage IoT critical data by creating licenses such as time limit and device limitation according to the weight condition of IoT critical information. Performance evaluation and proposed techniques have improved delay time and processing time by 7.6% and 10.1% on average compared to existing techniques.

최근 다양한 산업 분야에 적용되고 있는 사물인터넷(IoT)은 자동화와 디지털화하는 과정에서 끊임없이 진화하고 있다. 그러나, IoT 장치가 구축된 네트워크에서는 중간 노드 간의 IoT 중요 정보 관련 데이터의 공유, 개인정보보호 및 데이터 무결성 등의 연구가 아직도 활발하게 연구되고 있다. 본 연구에서는 IoT가 구축된 네트워크 환경에서 중간 노드에 부담을 주지 않으면서 구현이 쉬운 블록체인 기반의 IoT 중요 정보 관리 기법을 제안한다. 제안 기법은 중간 노드에 도착한 IoT 중요 정보에 대해서 임의 크기의 무작위 값을 할당하여 탈중앙화된 P2P 블록체인이 되도록 관리한다. 또한, 제안 기법은 IoT 중요 정보의 가중치 조건에 따라 시간제한, 장치 제한 등의 라이선스를 만들어 IoT 중요 데이터 관리가 수월하여지도록 한다. 성능평가, 제안 기법은 지연시간 및 처리시간이 기존 기법보다 평균 7.6%, 10.1%가 향상되었다.
