Abstract

Interest in 5G communication security has been growing recently amid growing expectations for 5G technology with faster speed and stability than LTE. However, 5G has so far included disparate areas, so it has not yet fully supported the issues of security. This paper proposes a blockchain-based IoT management model in order to efficiently provide the authentication of users using IoT in 5G In order to efficiently fuse the authentication of IoT users with probabilistic theory and physical structure, the proposed model uses two random keys in reverse direction at different layers so that two-way authentication is achieved by the managers of layers and layers. The proposed model applied blockchain between grouped IoT devices by assigning weights to layer information of IoT information after certification of IoT users in 5G environment is stratified on a probabilistic basis. In particular, the proposed model has better functions than the existing blockchain because it divides the IoT network into layered, multi-layered networks.

최근 LTE보다 빠른 속도와 안정을 가진 5G 기술에 대한 기대감이 증가하고 있는 가운데 5G 통신 보안에 대한 관심이 증가하고 있다. 그러나, 5G는 현재까지 이질적인 영역이 서로 포함되어 있어서 보안 영역에 대한 문제들을 아직 완벽하게 지원하고 있지 않다. 본 논문은 5G 환경에서 IoT 장치의 인증을 블록체인에 적용한 확률 기반의 IoT 관리모델을 제안한다. 제안 모델은 IoT 장치의 인증을 확률적 이론과 물리적 구조를 효율적으로 융합하기 위해서 n 계층의 IoT 사용자를 n+1 계층과 n-1 계층의 관리자가 쌍방향 인증이 이루어지도록 2개의 랜덤키를 역으로 사용한다. 제안 모델은 5G 환경의 IoT 사용자에 대한 인증을 확률적 기반으로 IoT 정보를 계층화시킨 후 IoT 정보를 가중치에 적용하여 그룹핑된 IoT 정보를 블록체인으로 연결한다. 또한, 제안 모델은 5G 네트워크를 계층화된 다층 네트워크로 분할하기 때문에 기존 블록체인보다 향상된 기능을 가진다.
